CBIR primitives, Wavelet transform


This paper presents two new primitives for representing the content of a video in order to be used in a Content Based Video Retrieval System. The techniques presented here compute first a multiresolution representation using the Haar transform. Two types of signatures are extracted afterwards, one based on multiresolution global color his tograms and the other one based on multiresolution lo cal color histograms. The tests performed in the exper iments include the recall measure achieved with the pro posed primitives using a database composed by 62 videos with 817 shots.
