Abstract:
An image processing apparatus comprising:a storage section arranged to store a plurality of images as encoded data; an input section arranged to input an image shape as information of an image to be retrieved by search; a generation section arranged to generate query data on the basis of the input image shape; and a determination section arranged to determine similarity between the input image shape and an image, which is expected to be obtained by decoding the encoded data, by making a comparison of the query data with the encoded data read out from said storage section, wherein the encoded data is obtained by sequentially encoding transform coefficients, which are obtained by a discrete wavelet transformation of an image and said determination section compares the query data and a synthesized sub-band which is the logical combination of a plurality of sub-bands obtained by the discrete wavelet transformation.
