EXIF-based imaged feature set for content engine
First Claim
1. A method for managing a collection of digital color images, comprising the steps of:
- analyzing digital color images in the collection, and for each digital color image analyzed partitioning that digital color image into a plurality of blocks, each block containing a plurality of transform coefficients, and extracting a feature set derived from transform coefficients of that digital image, the feature set comprising color features, edge features, and texture features including texture-type, texture-scale and texture-energy.

Abstract
An improved feature set and accompanying image-content-based management/search method/algorithm enable fast and effective searching of a collection 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 color features, edge features, and texture features including texture-type, texture-scale and texture-energy. The feature set of a query image is compared to the feature sets of images in the relevant search range to identify all similar images.
