Image Search & Similarity Matching
Many systems have image similarity matching
Dimensions of matching are color, texture, shape
Informedia has applied:
1. Color histograms for image similarity matching
2. Separate face detection and matching
3. Region-based analysis for matching image segments (much improved over 1)
4. Now, perceptual color clustering based on human sensitivity and perception
Area lacks standard test suites with human judgements to measure precision and recall
