Abstract:
1. A method for image recognition in a collection of digital images comprising: using a processor to perform the following steps: for each image in the collection, identifying any regions in the image corresponding to a face; storing said feature vectors in association with data relating to the associated face region, and selecting from an image at least one reference region including a face to be recognized; selecting from said plurality of image classifiers, at least one classifier on which said retrieval is to be based; determining for said reference region, a respective feature vector for each selected classifier; and wherein said step of determining feature vectors comprises: a. for each face region and any associated peripheral region, extracting respective features representative of the region; b. for each of said plurality of image classifiers, determining respective basis vectors according to said extracted features; and c. for the extracted features for each region, for each classifier, determining said feature vectors, based on each determined basis vector.
