IMAGE FEATURE SET BASED ON EXIF FOR CONTENT ENGINE

摘要

PPROBLEM TO BE SOLVED: To provide an image search algorithm for utilizing a feature set allowing a fast and high-reliability search result, and for utilizing a small thumbnail image. PSOLUTION: An improved feature set and accompanying image-content-based management/search method/algorithm enable fast and effective searching of a collection of a plurality of digital color images to identify a particular image or group of images. The feature set, which is designed for EXIF formatted thumbnail color images, is derived from select transform (e.g., DCT) coefficients of the individual color components of the searched images. The feature set comprises a plurality of color features, a plurality of edge features, and a plurality of texture features including texture-type, texture-scale and texture-energy. The feature set of a query image is compared to the feature sets of the plurality of images in the relevant search range to identify all similar images. PCOPYRIGHT: (C)2005,JPO&NCIPI
