The paper presents an algorithm for estimation of temperature of image. Colour temperature is important, perceptual feature describing colour and content of images. The main idea of the algorithm is to average pixel values of image, omitting the values which have meaningless influence on perception of colour temperature. It is done in an interactive procedure. The convergence of the procedure is discussed. The algorithm can be applied in image search/retrieval tasks and is proposed in the MPEG-7 colour temperature descriptor for estimation of colour temperature of images.
