Content based retrieval and recognition of objects represented in images is a challenging problem making it an active research topic. Shape analysis is one of the main approaches to the problem.
Content-based image retrieval and classification characterizes the image with a set of features and uses these features for classification and retrieval purposes. In some systems these features are used in a manner that allows the user to use an image as a query and find similar images in the database ( Latecki et al., 2000, Belongie et al., 2002, Zhang and Lu, 2003 ).

An Efficient Content-based Image Retrieval System Integrating Wavelet-based Image Sub-blocks with Dominant Colors and Texture Analysis ABSTRACT Multimedia information retrieval is a part of computer science and it is used for extracting semantic information from multimedia data sources such as image, audio, video and text.
Based Image Retrieval (CBIR) systems (8). Cbir uses three types of features to retrieve images: (1)Color (2) Shape (3) Texture. Content based image retrieval system aims to retrieve the most similar images as related to the given query image by the user. Assuming “color” feature, given a query image.
Abstract. Shape descriptors have been used frequently as features to characterize an image for classification and image retrieval tasks. For example, the patent office uses the similarity of shape to ensure that there are no infringements of copyrighted trademarks.
Content based image retrieval; Attribute based search;. Shape, texture, color,. In image classification and object recognition “attributes” are used to represent the images. An attribute has a name and a semantic meaning, but it is easy to recognize for a machine.
ABSTRACT Content based video retrieval is a way to simplify fast and accurate content access to video data. The advances in technology such as capturing, refining and transferring video content has advanced over the years, but still there is a lack of efficiency for retrieving content based video data.
A Shape Based Image Search Technique Aratrika Sarkar 1. used for classification of a flowered plant and a cactus plant. The authors use the Curvature Scale Space (CSS). In this study, we have developed an algorithm for shape based image retrieval and image search.

Now I'm trying Shape, where in algorithm it is mentioned that Based on the extracted shape features, image classification process has been performed using Support Vector Machine (SVM) tool. there is an inbuilt function for canny edge detection, what features does this outcome have? and how classification is done using SVM? please help me, please suggest me the relevant codes.

Princeton Shape Benchmark. The Princeton Shape Benchmark provides a repository of 3D models and software tools for evaluating shape-based retrieval and analysis algorithms. The motivation is to promote the use of standardized data sets and evaluation methods for research in matching, classification, clustering, and recognition of 3D models.
Now then we further classification technique based on Support Vector Machine is used to remove noise and printed text overlapping on the extracted signature images. Finally, a global shape-based feature is computed for each signature image. Now presented a signature based document retrieval technique from documents with cluttered background.This thesis investigates shape based image retrieval techniques. Shape is an important low level image feature. In this thesis, a new shape descriptor, called generic Fourier descriptor (GFD) has been developed. The new shape descriptor is desirable for generic shape description and retrieval. It satisfies the six principles set by MPEG-7: good.Shape is one of the primary low level image features in the newly emerged Content Based Image Retrieval (CBIR). Many shape representations have been proposed, and they are generally classified into contour-based methods and region-based methods. Contour-based methods capture shape boundary features while ignore shape inner content.
