摘要： 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.

摘要： The present invention relates to an image-processing device and a method of assigning pixel values to adjacent pixel locations in an image (705) having unassigned pixel values. The method comprises the steps of generating first propagation pixel values (730) and first propagation weights (735) for propagating the first propagation pixel values (730) along a first direction towards the adjacent pixel locations by: generating the first propagation pixel values (730) for propagation to the adjacent pixel locations in the first direction, the first propagation pixel values (730) being based at least on assigned pixel values in a first region adjacent to the unassigned pixel locations; generating first propagation weights (735) for the first propagation pixel values (730) to account for discontinuities in pixel values of assigned pixel values in a second region adjacent to the hole along the first direction, such that the occurrence of a discontinuity in said assigned pixel values along the first direction results in lower first propagation weights (735); and assigning pixel values to the adjacent pixel locations based at least in part on the first propagation pixel values (730) and first propagation weights (735). The invention further relates to a computer program and a computer program product comprising the program for implementing the method.

摘要： A combination of image data and depth data is supplied defining luminance and/or color for image positions in an image and distance to objects visible at said image positions respectively. The image data and the depth data are compressed by a compressor (120) and decompressed by a decompressor (16). The depth data is dilated before said compressing, to move an edge between a region of image positions with a relatively smaller distance and a region of image positions with a relatively greater distance towards the region of image positions with a relatively greater distance.

摘要： A method of compressing and decompressing a sequence of images comprises segmenting a first and second image (30, 32) into regions (35a,b, 37a,b) of pixel locations. For each of a plurality of the regions (35a,b, 37a,b) a first transformation parameters (Da,b) such as a translation is computed to transformation the region (35a,b, 37a,b) from the first image to the and second image (30,32). Holes (38) are detected that are left between the regions (35a,b, 37a,b) when transforming the regions from the first image to the second image (30, 32) according to the first transformation parameters (Da,b).For each of the holes (38), a computed image property of the second image (32) in the hole is compared with corresponding computed image properties of the regions (35a,b, 37a,b) adjoining the hole. For each of the holes (38), one of the regions (35a,b, 37a,b) adjoining the hole (38) is selected, for which the image property is closest to the image property of the hole (38). A further image is encoded by means of correction information that represents a difference between the further image (40) and a predicted image, wherein the predicted image is obtained by transforming the regions (35a,b, 37a,b) with second transformation parameters derived from the first transformation parameters (Da,b). In each hole (46) in the predicted image (40) information from the second image (32), is substituted, transformed according to a transformation parameter value derived from the first transformation parameters (Da,b) of the selected region for the hole (38) in the second image that corresponds to the hole (46) in the predicted image. On decoding the predicted image is reconstructed and the correction information is used to computed a decompressed further image.
