ABSTRACT:
A method, apparatus and computer program product are provided for building an image index and for searching and querying by image colors from a plurality of images including images from the internet or other network environment. First an index is built for each of the plurality of images. A selected number of levels is identified for image processing, and an upper resolution and a lower resolution are identified for each of the selected number of levels for image processing. An image is filtered at each selected level. A sample of pixels is acquired and stored at each selected level in the index. At query time, an image color is selected. A entry of the index is acquired. The acquired entry is compared with the selected image color. A match is identified responsive to the acquired entry being near the selected image color.
