    摘要: In block-based motion or depth estimation, a block is assigned a motion or depth value as a result of minimizing the matching error over a limited set (45) of candidate values. This set (45) usually comprises one random motion or depth value, to prevent the algorithm from stacking in local minimums. The method and system according to the invention instead add to this set (45) one motion or depth value based on properties of the image. A history of temporal changes for chosen motion or depth values is recorded, a histogram is made and a plurality of values is created in proportion to the histogram. The one added value is chosen from this plurality. Additionally, information about the direction of the changes is recorded to prevent oscillation. An apparatus for adapting a video signal (40) uses the chosen candidate values to create an enhanced version of the video signal (40).

    摘要: A display system (100) for displaying images from different data streams (1,2) simultaneously is described. Images corresponding to the first data stream (1) are shown to a first observer (106) in a vehicle and images corresponding to the second data stream (2) are shown to a second observer (108) in the vehicle. The display system (100) comprises: a display screen (102) for generating a first one of the images and a second one of the images; and an optical selction screen (104) for selectively passing the first one of the images in a first direction (101) towards the first observer (106) and passing the second one of the images in a second direction (103) towards the second observer (108).

    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: In a method for relative depth of parts of one or more digital images, the digital images are regularized by segmentation, and at least part of the pixels of the images are assigned to respective segments. The realtive motion of the segments for successive images is estimated by image matching. The image features of the segments are regularized by dual segmetation, in which the edges of the segments are found, pixels are assigned to the edges, and dual segments are defined. The relative motion of the dual segments for successive images is estimated by image segment matching in order to determine the relative depth order of the image segments.

    摘要: In block-based motion or depth estimation, a block is assigned a motion or depth value as a result of minimizing the matching error over a limited set (45) of candidate values (20, 21, 22, 23). When the chosen candidate value (23) is an extreme value of the set, it is impossible to predict how remote this value is from the real minimal matching error. To overcome this problem, the method and system for choosing an optimal candidate value choose a new candidate (30) beyond the extreme value (23). When this new candidate (30) then has the lowest matching error, additional new candidates are chosen until it no longer has. An apparatus for adapting a video signal (40) uses the chosen candidate values to create an enhanced version of the video signal (40).

    摘要: Disclosed is a visual communication signal (32) which comprises image model information (10) for generating 3-D images. The image model information (10) may comprise a 3-D image model, e.g. a 3-D wireframe model or a 3-D voxel map. Some of the generated 3-D images may have a relatively low image quality. The visual communication signal (32) further comprises image enhancement information (20) corresponding to at least part of the 3-D images for enhancing the image quality of the generated 3-D images. This image enhancement information (20) may comprise image information corresponding to one or more single viewpoints (22, 24) and/or image information corresponding to one or more ranges of viewpoints (26, 28). The visual communication signal (32) may be transmitted from a transmitter (30) to a receiver (34) in a visual communication system (40) such as a 3-D television system or a 3-D teleconferencing system. Alternatively, the visual communication signal (32) may be carried by a tangible medium, e.g. a CD-ROM or a DVD-ROM.
