The Image Shape Spectrum for Image Retrieval
نویسنده
چکیده
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 databases and a database of 3D objects, for which the method reaches an ideal recognition rate. Le spectre de forme pour l'indexation d'images R esum e : Nous pr esentons une technique fond ee sur l'apparence pour carac-t eriser et rechercher des images dans une base. Notre m ethode est invariante a la translation, a la rotation et au changement d' echelle et capte l'information signiicative de l'image sans recours a la segmentation. Elle est egalement tr es bien adapt ee au faible changement de point de vue et elle est egalement robuste au bruit et aux occultations. Nous pr esentons des exemples de recherche dans plusieurs grandes bases de donn ees, contenant des images de visages ou des images d'objets tridimensionnels. Pour cette derni ere base la m ethode atteint un taux de reconnaissance id eal.

Image Retrieval Using Dynamic Weighting of Compressed High Level Features Framework with LER Matrix
In this article, a fabulous method for database retrieval is proposed. The multi-resolution modified wavelet transform for each of image is computed and the standard deviation and average are utilized as the textural features. Then, the proposed modified bit-based color histogram and edge detectors were utilized to define the high level features. A feedback-based dynamic weighting of shap...
