    • A video encoder (100) comprises a receiver (101) which receives an uncompressed video signal. An encoding element (103) generates a compressed video signal in accordance with a compression algorithm, such as an MPEG-2 encoding algorithm. In addition, a feature point processor (105) generates feature point data (105) in response to the uncompressed signal, and an output processor (107) generates an output video signal which comprises the compressed video signal and the feature point data. The output signal is received by a receiver (201) of a video signal processor (200). An extraction processor (203) extracts the feature point data and feeds it to a video processor unit (207) which processes the compressed video signal in response to the feature point data. The separate and independent generation of feature point data, such as feature point movement data or tracks using the uncompressed (original) video signal, eliminates or reduces the impact of compression artifacts, inaccuracies and errors on feature point locations and trajectories when these are detected using the compressed signal.

    • 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).
