This book was released on 2012-12-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shape detection techniques are an important aspect of computer vision and are used to transform raw image data into the symbolic representations needed for object recognition and location. However, the availability and application of research data relating to shape detection has traditionally been limited by a lack of computational and mathematical skill on the part of the intended end-user. As a result progress in areas such as the automation of visual inspection techniques, where shape detection couls play a pivotal role, has been relatively slow. In this volume, Violet Leavers, an established author and researcher in the field, examines the Hough Transform, a technique which is particularly relevant to industrial applications. By making computational recipes and advice available to the non-specialist, the book aims to popularize the technique, and to provide a bridge between low level computer vision tasks and specialist applications. In addition, Shape Detection in Computer Vision Using the Hough Transform assesses practical and theoretical issues which were previously only available in scientific literature in a way which is easily accessible to the non-specialist user. Shape Detection in Computer Vision Using the Hough Transform fills an obvious gap in the existing market. It is an important textbook which will provide postgraduate students with a thorough grounding in the field, and will also be of interest to junior research staff and program designers.

Available in PDF, EPUB and Kindle. Book excerpt: From the study of the presion of the robotic hand, the following general conclusions may be drawn: a) Object shapes and dimensions have been analyzed through PC-based 2D image processing technique and the information about the object shape has been incorporated in the three-tier hierarchy of the control system for determining the preshape of the fingers during manipulation. b) A CCD camera has been employed to grab the image of the object to be gripped and a vision-based algorithm has been developed for analyzing the stable grasp positions and orientations. It has been found that the vision assistance can minimize the down time for grasping an object in a pre-defined manner by preshaping the fingers.

Download or read book Measuring Shape written by F. Brent Neal and published by CRC Press. This book was released on 2017-12-19 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: "John Russ is the master of explaining how image processing gets applied to real-world situations. With Brent Neal, he’s done it again in Measuring Shape, this time explaining an expanded toolbox of techniques that includes useful, state-of-the-art methods that can be applied to the broad problem of understanding, characterizing, and measuring shape. He has a gift for finding the kernel of a particular algorithm, explaining it in simple terms, then giving concrete examples that are easily understood. His perspective comes from solving real-world problems and separating out what works in practice from what is just an abstract curiosity." —Tom Malzbender, Hewlett-Packard Laboratories, Palo Alto, California, USA Useful for those working in fields including industrial quality control, research, and security applications, Measuring Shape is a handbook for the practical application of shape measurement. Covering a wide range of shape measurements likely to be encountered in the literature and in software packages, this book presents an intentionally diverse set of examples that illustrate and enable readers to compare methods used for measurement and quantitative description of 2D and 3D shapes. It stands apart through its focus on examples and applications, which help readers quickly grasp the usefulness of presented techniques without having to approach them through the underlying mathematics. An elusive concept, shape is a principal governing factor in determining the behavior of objects and structures. Essential to recognizing and classifying objects, it is the central link in manmade and natural processes. Shape dictates everything from the stiffness of a construction beam, to the ability of a leaf to catch water, to the marketing and packaging of consumer products. This book emphasizes techniques that are quantitative and produce a meaningful yet compact set of numerical values that can be used for statistical analysis, comparison, correlation, classification, and identification. Written by two renowned authors from both industry and academia, this resource explains why users should select a particular method, rather than simply discussing how to use it. Showcasing each process in a clear, accessible, and well-organized way, they explore why a particular one might be appropriate in a given situation, yet a poor choice in another. Providing extensive examples, plus full mathematical descriptions of the various measurements involved, they detail the advantages and limitations of each method and explain the ways they can be implemented to discover important correlations between shape and object history or behavior. This uncommon assembly of information also includes sets of data on real-world objects that are used to compare the performance and utility of the various presented approaches.

Download or read book 3D Shape Analysis written by Hamid Laga and published by John Wiley & Sons. This book was released on 2018-12-14 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-depth description of the state-of-the-art of 3D shape analysis techniques and their applications This book discusses the different topics that come under the title of "3D shape analysis". It covers the theoretical foundations and the major solutions that have been presented in the literature. It also establishes links between solutions proposed by different communities that studied 3D shape, such as mathematics and statistics, medical imaging, computer vision, and computer graphics. The first part of 3D Shape Analysis: Fundamentals, Theory, and Applications provides a review of the background concepts such as methods for the acquisition and representation of 3D geometries, and the fundamentals of geometry and topology. It specifically covers stereo matching, structured light, and intrinsic vs. extrinsic properties of shape. Parts 2 and 3 present a range of mathematical and algorithmic tools (which are used for e.g., global descriptors, keypoint detectors, local feature descriptors, and algorithms) that are commonly used for the detection, registration, recognition, classification, and retrieval of 3D objects. Both also place strong emphasis on recent techniques motivated by the spread of commodity devices for 3D acquisition. Part 4 demonstrates the use of these techniques in a selection of 3D shape analysis applications. It covers 3D face recognition, object recognition in 3D scenes, and 3D shape retrieval. It also discusses examples of semantic applications and cross domain 3D retrieval, i.e. how to retrieve 3D models using various types of modalities, e.g. sketches and/or images. The book concludes with a summary of the main ideas and discussions of the future trends. 3D Shape Analysis: Fundamentals, Theory, and Applications is an excellent reference for graduate students, researchers, and professionals in different fields of mathematics, computer science, and engineering. It is also ideal for courses in computer vision and computer graphics, as well as for those seeking 3D industrial/commercial solutions.

Available in PDF, EPUB and Kindle. Book excerpt: Shape matching and recognition is a fundamental aspect of many problems in computer vision, including object or scene recognition, moving tracking and object detection, etc. While rigid shape matching is relatively well understood, matching shapes undergoing non-rigid deformations remains challenging. Moreover, shape generation is also a challenging task since nearly all approaches face the same difficulty: background clutter. The aim of this book is to propose novel approaches to generate, represent and match object shapes. To achieve this, the following three aspects are particularly explored: Shape generation, shape representation and shape matching. Shape generation is applied based on shape contour detection which is able to locate an object, identify its contour parts, and segment out its contour. Shape representation looks for effective and perceptually important shape features based on either shape boundary or region information. Shape matching aims to calculate the overall similarity (or dissimilarity) between two object shapes. Based on the proposed approaches, two shape-based applications are introduced and assessed.

Available in PDF, EPUB and Kindle. Book excerpt: "A simulated shape recognition system using feature extraction was built as an aid for designing robot vision systems. The simulation allows the user to study the effects of image resolution and feature selection on the performance of a vision system that tries to identify unknown 2-D objects. Performance issues that can be studied include identification accuracy and recognition speed as functions of resolution and the size and makeup of the feature set. Two approaches to feature selection were studied as was a nearest neighbor classification algorithm based on Mahalanobis distances. Using a pool of ten objects and twelve features, the system was tested by performing studies of hypothetical visual recognition tasks."--Abstract.

Download or read book Shape Recognition for Plane Closed Curves Using Error Model of an Elliptical Fit and Fourier Descriptors written by Onkar Nitin Raut and published by . This book was released on 2011 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the past few decades there has been profound interest shown in robotics and computer vision specially towards object recognition. While there are many techniques available to choose from, an investigation is carried out in this work on techniques that use Fourier descriptors for analyzing and modelling objects of inter¬est. Also, a new technique for generating Fourier descriptors is designed and the performance is evaluated against existing techniques for generating Fourier descrip¬tors. This new technique generates the Fourier descriptor by fitting an ellipse to a shape normalized boundary segment extracted from an image of a plane close object and finding the error of the fit. This error forms the signal input for generating the Fourier descriptor. Experiments are performed using the new technique which involve classifying a database of leaves using a simple k-Nearest Neighbours classifier. Results deduced from the performance of this newly designed technique indicate improved consistency and accuracy over previous methods. This encouraged the development of a real time recognition system used to recognize known objects of interest in an unknown environment as an application towards computer vision and robotics.

Available in PDF, EPUB and Kindle. Book excerpt: Perceiving accurate 3D object shape is important for robots to interact with the physical world. Current research along this direction has been primarily relying on visual observations. Vision, however useful, has inherent limitations due to occlusions and the 2D-3D ambiguities, especially for perception with a monocular camera. In contrast, touch gets precise local shape information, though its efficiency for reconstructing the entire shape could be low. In this thesis, we propose a novel paradigm that efficiently perceives accurate 3D object shape by incorporating visual and tactile observations, as well as prior knowledge of common object shapes learned from large-scale shape repositories. We use vision first, applying neural networks with learned shape priors to predict an object’s 3D shape from a single-view color image. We then use tactile sensing to refine the shape; the robot actively touches the object regions where the visual prediction has high uncertainty. Our method efficiently builds the 3D shape of common objects from a color image and a small number of tactile explorations (around 10). Our setup is easy to apply and has potentials to help robots better perform grasping or manipulation tasks on real-world objects.
