摘要： In general, this disclosure relates to techniques for adaptively determining a rate for intra-coding segments (e.g., macro-blocks) of video data within a sequence of video units (e.g., frames) in response to the receipt of error feedback that is provided by a video decoder. One example method includes receiving feedback from a video decoder that indicates an error associated with coded video data, and, upon receipt of the feedback, determining a rate for intra-coding a specified number of segments of video data for each video unit within a sequence of video units, wherein an intra-coding of segments of video data within one video unit is independent of a coding of segments of video data within other video units within the sequence.

摘要： A method of encoding display output of a computer using a block-based video encoder, such as H.264 includes receiving display update information, the display update information specifying at least one changed display area. Pixel data associated with the at least one changed area is also received. For each image block of an output frame to be encoded, the encoder determines whether the image block intersects one or more of the changed areas. A block skip indication is encoded for each image block not intersecting at least one changed area, and pixel data is encoded for intersecting blocks. An encoded output frame is then generated including the block skip indications and encoded pixel data.

摘要： Methods of data encoding using trees formed with logic gates are described which lead to spatial compression of image data. Data encoding is achieved using a five-level wavelet transform, such as the Haar or the 2/10 transform. A dual transform engine is used, the first and engine being used for the first part of the first-level transform, the second part of the first-level transform and the subsequent-level transforms being performed by the second transform engine within a time interval which is less than or equal to the time taken by the first transform engine to effect the part-transform. Each bit plane of the resulting coefficients is then encoded by forming a tree structure from the bits and OR logical combinations thereof. Redundant data are removed from the resulting tree structure, and further data can be removed by using a predetermined compression profile. The resulting blocks of compressed data are of variable length and are packaged with sync words and index words for transmission so that the location and identity of the transformed data blocks can be determined from the received signal.

摘要： The invention relates to a method for identifying motion in an image sequence (S), which method involves an image processing device (22) ascertaining a change of position of image features (M1 to M4) in a current image (A) in respect of a reference image (reference 1), having the following steps: paired association of corresponding image features (M1-M1' to M4-M4'), one of which can be found in the current image (A) and one of which can be found in the reference image (reference 1), and determination of model parameters describing the change of position for a motion model (H) on the basis of the image features (M1-M1' to M4-M4') which are associated with one another. The estimation of the model parameters needs to be improved. To this end, at least one static region (98, 60) is ascertained for the current image, in which static region the change of position of the image contents contained therein is smaller than a predetermined amount, and the model parameters are determined by using only image features (M1 to M4, M1' to M4') which can be found outside the at least one static region (98, 60).

摘要： The present invention relates to an image processor (1) that is configured to compare (7) a single frame included in the received signal (3) with a preceding processed frame so as to detect changes. In order to enable compression in as compact a format as possible the processor (1) is configured to detect (7) changes by dividing the pixels of a single frame into movement blocks and to detect the movement block as changed if in said movement block there is a given number of pixels whose characteristic value change as compared with the corresponding pixels of the preceding processed frame exceeds a predetermined threshold, to set the values of the pixels of the unchanged movement blocks in the frame under process to predetermined values and to generate a signal (4) that indicates the changes.
