A method of representing a colour image comprises selecting a region of the image, selecting one or more colours as representative colours for the region and, for a region having two or more representative colours, calculating for each representative colour at least two parameters related to the colour distribution in relation to the respective representative colour and using said parameters to derive descriptors for the image region. Alternatively a function approximating the colour distribution for each representative colour or an indication of the spread of the colour distribution of each representative colour can be used to derive descriptors of the image region. A database of images can be represented using these descriptors which can be searched by comparing the descriptors with that of a user selected image.
