摘要： The invention relates to compression of a pixel block (300) of depth values. A reference codeword (410) is determined as a representation of a reference depth value. A row (420) and a column (430) slope codeword are determined as representations of a basic depth slope for the rows (310) and columns (320) in the block (300), respectively. Representations indicating pixel positions where a slope change occurs along at least a portion of a row (310) or column (320) is determined for at least a subset of the rows (310) or columns (320). A mode codeword (440) is determined as a representation of a set of multiple slope correction patterns. A respect pattern codeword (450) is then selected for rows (310) or columns (320) as identifier of one of the slope correction patterns.

摘要： First and second codewords are determined, based on first feature vector components of the image elements in an image block, as representations of a first and second component value. Third and fourth codewords are determined, based on second vector components, as representations of a third and fourth component value. First N1 and second N2 resolution numbers are selected based on the relation of a distribution of the first vector components and a distribution of the second vector components. N1 additional component values are generated based on the first and second component values and N2 additional component values are generated based on the third and fourth component values. Component indices indicative of the generated component values are then provided for the different image elements.

摘要： The invention is applied to image processing schemes by providing at least one auxiliary block processing mode in addition to the standard default block processing mode of the scheme. An image to be decoded is divided into a number of image blocks (800) having multiple image elements (810). These blocks (800) are individually compressed by means of a default compressing mode or an auxiliary compressing mode, depending on which mode that results in a smallest error metric. A portion (980) of the resulting compressed block (900) is used to discriminate between the two modes. In the auxiliary mode, the remaining payload portion (990) of the compressed block (900) can be used for encoding purposes, whereas the default mode can in addition utilize the discriminating portion (980).

摘要： In an image scaling method, an image (10) having an original row/column resolution NO is scaled into a scaled image (30) having a target row/column resolution NT. A filter set comprising α filters is provided, where α being equal to a quotient of the target resolution NT and a common denominator k of the original resolution NO and the target resolution NT. The common denominator k is a positive number larger than one. For at least one row/column (16/18) of image elements (12), a filtered image element (32) of the scaled image (30) is formed, for each filter in the filter set, by filtering at least one image element (12) of the at least one row/column (16/18) using the filter. This image element formation is repeated up to k times over the at least row/column (16/18) to form a scaled row/column (36/38) of image elements (32) of the scaled image (30).

摘要： A pixel block (300) is compressed by providing a respective color component prediction for each pixel (310-318) in the block (300). A difference between color components of two neighboring pixels (312, 316) is calculated and compared to a threshold. If the difference is smaller than the threshold, the prediction is calculated based on a first linear combination of the color components of these two neighboring pixels (312, 316). However, if the difference exceeds the threshold, a second or third linear combination of the color components of the neighboring pixels (312, 316) is employed a prediction. A guiding bit (470) associated with the selected linear combination. A prediction error is calculated based on the color component of the pixel (318) and the provided prediction. The compressed block (400) comprises an encoded representation (480) of the prediction error and any guiding bit (470).

摘要： In an image-encoding scheme, an input image is decomposed into several image blocks (600) comprising multiple image elements (610). The image blocks (600) are encoded into encoded block representations (700). In this encoding, color weights are assigned to the image elements (610) in the block (600) based on their relative positions in the block (600). At least two color codeword (710, 720, 730, 740) are determined, at least partly based on the color weights. These codewords (710, 720, 730, 740) are representations of at least two color values. The original colors of the image elements (610) are represented by color representations derivable from combinations of the at least two color values weighted by the assigned color weights.
