Abstract:
1. A method of representing a group of images using at least one processor to process signals corresponding to the images, the method comprising: obtaining image dominant colour representations for each image in the group of images, the dominant colour representations expressing the images in terms of one or more of dominant colour values, and where each of the image dominant colour representations has one or more components including at least one image dominant colour value, and a variance indicating colour distribution variance of the image with respect to the dominant colour value, said variance being calculated for each image dominant colour using where j indexes the color component, m determining, using a processor, the values of one or more colours that are dominant for the group of images by combining the image dominant colour representations; generating a group dominant colour representation for the group of images based on the combined image dominant colour representation.
