Shape measures for image retrieval
One of the main goals in Content Based Image Retrieval (CBIR) is to incorporate shape into the process in a reliable manner. In order to overcome the difficulties of directly obtaining shape information (in particular avoiding region segmentation) we develop several shape measures that tackle the problem in an indirect manner, requiring only a minimal amount of segmentation. A histogram-based s...
متن کاملShape Measures for Content Based Image Retrieval: A Comparison
A great deal of work has been done on the evaluation of information retrieval systems for alphanumeric data. The same thing can not be said about the newly emerging multimedia and image database systems. One of the central concerns in these systems is the automatic characterization of image content and retrieval of images based on similarity of image content. In this paper, we discuss effective...
متن کاملevaluation of dissimilarity measures for image retrieval and classification
in this paper, the performance of 11 different distances for image retrieval and classification, based on color, shape and texture, is evaluated. the precision-recall measure and the correct classification rate of the k-nn classifier are used to evaluate retrieval and classification performances, respectively. the experimental results for a database of 1000 images from 10 different semantic gro...
متن کاملThe Image Shape Spectrum for Image Retrieval
We present an appearance-based technique for image characterization and retrieval. Our method is translation/rotation and scale-invariant and encodes the signiicant data in the image without using any segmenta-tion. It is also very well suited to small viewpoint changes and is robust to noise and occlusion. We present several retrieval examples in large benchmark databases, including face datab...
متن کاملShape-based Image Retrieval
Shape-based Image Retrieval By Aditya Vailaya Retrieval e ciency and accuracy are two important issues in designing a contentbased database retrieval system. We propose a new image database retrieval method based on shape information. This system achieves both the desired e ciency and accuracy using a two-stage hierarchy: in the rst stage, simple and easily computable statistical shape features...
