A method of encoding an image (OI) represented by pixel values comprises the steps of: - producing a partial image (PI) by selecting a number of pixel values, - outputting the partial image (PI), - producing a combined partial image using the current partial image and any preceding partial images, if available, - producing a reconstructed image (RI') using the combined partial image, determining a quality measure of the reconstructed image, and - repeating the above steps if the determined quality measure is smaller than a threshold value. Each partial image contains at least some pixels that have not been previously selected. The combined partial image contains fewer pixels than the original image. The step of producing a reconstructed image preferably involves a hole filling process. An encoding device (1) is arranged for carrying out these method steps and comprises a selection unit (12), an accumulation unit (15), a reconstruction unit (16) and a correspondence unit (17). |
