摘要： The invention is related to a method for compressing images. The proposed method comprises associating perceptual importance parameters with pixels of the image, applying a transform on the image, partitioning the transformed image into code blocks and encoding coefficient bits of a given code block together from a most significant bit plane towards a least significant bit plane, wherein encoding of at least one coefficient is truncated at a truncation bit plane depending on the perceptual importance parameter associated with the pixel to which said code block coefficient corresponds. Truncating encoding of coefficients in dependency on the perceptual importance of the pixel associated with the coefficient allows for truncating coefficients corresponding to perceptually less important pixels at more significant bit planes. So, the overall perceptual quality of the compressed image is enhanced.

摘要： An algorithm for efficiently compressing floating-point data in 3D meshes is disclosed. 3D meshes are represented by topology data, geometry data and property data. Geometry data specify vertex locations and are usually represented by floating-point coordinates. While geometry data are usually compressed by quantization, prediction and entropy coding, the present invention uses no prediction. A floating-point number consists of mantissa and exponent, and normally the exponent, sign and mantissa are compressed separately. A method for encoding floating-point formatted data comprises determining if a current floating-point value was previously stored in a memory, storing the current value in the memory if it was not previously stored in the memory, and encoding it. Otherwise, if the current floating-point value was previously stored in a memory, the storage position of the value within the memory is determined and a reference pointing to the storage position is encoded.

摘要： The invention is related to prediction of a lost or damaged block of an enhanced spatial layer frame.A method for predicting a lost or damaged block of an enhanced spatial layer frame comprises the steps of determining an adjuvant frame in the enhanced spatial layer by help of reference information from a lower spatial layer frame corresponding said enhanced spatial layer frame, generating an information reduced block by help of said adjuvant frame and predicting the lost or damaged block by help of the information reduced block.The reference information of the corresponding lower spatial layer frame can be decoded independently from any lower spatial layer reference frame and the adjuvant enhanced spatial layer frame is already decoded. Thus, the computational effort is reduced. By generation of the information reduced block the prediction is made smoother which makes it less vivid and therefore less salient to a user.

摘要： In the case of packet loss during transmission over an error-prone transmission channel, some decoders may perform error concealment. In real-time systems, application decoders must handle the data loss alone and find out which data are missing. A special syntax within a packet-based framework is provided which is based on identifying and indicating the relationship between RTP packets and the application layer data they carry, before the packets are fed to the multi-layer application decoder. This helps the decoder to employ proper error concealment techniques in time, and prevents unnecessary processing in the decoder. A data stream comprises RTP packets containing application data of a multi-layer application, wherein an RTP packet (p2) contains two kinds of application layer information (NBf, NBn): one relating to the next RTP packet (p3), and one relating to the previous RTP packet (p1). In case of packet loss, the decoder can immediately determine the amount and type (VCLx) of missing data.

摘要： The invention is related to a method for encoding a sequence of integers, to a storage device and to a signal carrying such encoded sequence and to a method for decoding such encoded sequence.Said method comprises the steps of identifying a contiguous sub-sequence in the sequence of integers wherein said sub-sequence comprises interrelated integers having a same prefix when being variable length encoded and an independent last integer, and forming a code for the contiguous sub-sequence by help of code for an indication of the number of interrelated integers in said contiguous subsequence, a code of a prefix indication and the suffixes of variable length codes of the integers in the contiguous is sub-sequence.Thus, if there are n integers of which each is encoded with the same prefix then, instead of n individual prefixes for the integers, a single prefix for the contiguous subsequence is sufficient.
