Download or read book Method for Contour Extraction for Object Representation written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Contours are extracted for representing a pixelated object in a background pixel field. An object pixel is located that is the start of a new contour for the object and identifying that pixel as the first pixel of the new contour. A first contour point is then located on the mid-point of a transition edge of the first pixel. A tracing direction from the first contour point is determined for tracing the new contour. Contour points on mid-points of pixel transition edges are sequentially located along the tracing direction until the first contour point is again encountered to complete tracing the new contour. The new contour is then added to a list of extracted contours that represent the object. The contour extraction process associates regions and contours by labeling all the contours belonging to the same object with the same label.

Download or read book Boundary Extraction Methods for Segmentation Representation and Description in Digital Image Processing written by Fahd Badih el-Zoghet and published by . This book was released on 1999 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boundary extraction of regions, sets, or objects has been an active research area in digital image processing from the mid-1980s onward. A significant amount of work on this topic, using morphological operations, has been done in Europe since the 1970s. Boundary Extraction of objects or regions, which have been segmented out of an image, is an early step in the representation and description of these objects or regions. The importance of representation and description emerges from the need to represent an image before proceeding to other techniques in the operation of most automated image analysis systems.--The popular technique, Contour Tracing method, for boundary extraction was proposed and studied by Q. Wang and R.J. Clarcke in 1994. Since that time, this technique has been successfully applied for the purpose of boundary extraction.

Download or read book Object Representation and Matching Based on Skeletons and Curves written by Christian Feinen and published by Logos Verlag Berlin GmbH. This book was released on 2016-05-31 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is dedicated to the problem of object recognition in the three-dimensional space. Instead of using exclusively the information typically transported by a two-dimensional image, the concept of this work additionally incorporates the third dimension, namely the depth. The depth data itself is captured by sensors capable of measuring the distance from the device's position to those objects residing inside its field of view. The actual recognition process is implemented in analogy to the Path Similarity Skeleton Graph Matching (PSSGM). Basically, this method represents a 2D object by its skeleton and uses the idea of shortest paths to describe it. Finally, the similarity between two objects is calculated based on the Hungarian method. The contribution of the current work maps this approach into the three-dimensional space and applies it to 3D objects. While one of the experiments aims at the recognition of 3D chairs and tables, another one is devoted to the registration of fully segmented vascular structures. Excellent and promising recognition results are achieved in challenging evaluation setups showing that the 3D version of the PSSGM has the potential to solve complex recognition tasks.

Download or read book Computer Architectures for Spatially Distributed Data written by Herbert Freeman and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: These are the proceedings of a NATO Advanced Study Institute (ASI) held in Cetraro, Italy during 6-17 June 1983. The title of the ASI was Computer Arehiteetures for SpatiaZZy vistributed Vata, and it brouqht together some 60 participants from Europe and America. Presented ~ere are 21 of the lectures that were delivered. The articles cover a wide spectrum of topics related to computer architecture s specially oriented toward the fast processing of spatial data, and represent an excellent review of the state-of-the-art of this topic. For more than 20 years now researchers in pattern recognition, image processing, meteorology, remote sensing, and computer engineering have been looking toward new forms of computer architectures to speed the processing of data from two- and three-dimensional processes. The work can be said to have commenced with the landmark article by Steve Unger in 1958, and it received a strong forward push with the development of the ILIAC III and IV computers at the University of Illinois during the 1960's. One clear obstacle faced by the computer designers in those days was the limitation of the state-of-the-art of hardware, when the only switching devices available to them were discrete transistors. As aresult parallel processing was generally considered to be imprae tieal, and relatively little progress was made.
