摘要： A method and apparatus for encoding and decoding video performs transformation of at least a portion of a high-resolution video frame into a low resolution image and a plurality of enhancement data sets, encodes the low resolution image as a primary coded picture in a bitstream format and encodes each of the plurality of enhancement data sets as a different redundant coded picture in the bitstream format.

摘要： A method and apparatus for video encoding using improved last significant coefficient coding are disclosed. According to the present invention, a location of last significant coefficient in the transform block is encoded to generate one or more syntax elements and a maximum value of the syntax elements is dependent on a block size of the transform block and a zero-out threshold, where coefficients of the transform block with coordinates greater than the zero-out threshold are set to zero. A method and apparatus for video decoding using improved last significant coefficient coding are also disclosed.

摘要： An apparatus and method are for intra-frame spatial scalable video encoding. The method codes a low resolution base layer video bitstream from low resolution base layer video using a single layer encoder, and codes an enhancement layer in which individual videos frames are represented by wavelet coefficients for an LL residual sub-band, an HL sub-band, an LH sub-band; and an HH sub-band. The LL residual sub-band is generated as a difference of an LL sub-band and a recovered version of the base layer video bitstream.

摘要： A system includes a first set of subband filter banks, a second set of subband filter banks, a low-resolution base encoder, and a high-resolution enhancement encoder. The first set of subband filter banks performs subband analysis on a full resolution source video frame to generate a subband representation comprised of a lowpass subband and multiple highpass subbands. The second set of the filter banks decomposes the lowpass subband into aliasing subband components and aliasing-free subband components. The low-resolution encoder encodes the aliasing-free subband components, to generate an encoded video signal with minimal or no aliasing subband components. The highpass subbands from the first set of filter banks, the aliasing subband components, and optional refinements of aliasing-free subband components are encoded by the high-resolution enhancement encoder to provide further information for recovering video at full resolution.

摘要： Disclosed is an image encoder that divides (1000) a digital image into a set of "macroblocks." If appropriate, a macroblock is "downsampled" (1004) to a lower resolution. The lower-resolution macroblock is then encoded by applying spatial (and possibly temporal) prediction (1006). The "residual" of the macroblock is calculated (1010) as the difference between the predicted and actual contents of the macroblock. The low-resolution residual is then either transmitted to an image decoder or stored for later use (1010). In some embodiments, the encoder calculates (1008) the rate-distortion costs of encoding the original-resolution macroblock and the lower-resolution macroblock and then only encodes (1010) the lower-resolution macroblock if its cost is lower. When a decoder receives (1104) a lower-resolution residual, it recovers the lower-resolution macroblock using standard prediction techniques (1106). Then, the macroblock is "upsampled" (1110) to its original resolution by interpolating the values left out by the encoder. The macroblocks are then joined (1114) to form the original digital image.
摘要翻译：公开了一种图像编码器，其将（1000）数字图像划分为一组“宏块”。如果合适，则将宏块“下采样”（1004）降低到较低的分辨率。然后通过应用空间（和可能的时间）预测（1006）来对低分辨率宏块进行编码。计算宏块的“残差”（1010）作为宏块的预测和实际内容之间的差。然后将低分辨率残差传送到图像解码器或存储以供稍后使用（1010）。在一些实施例中，编码器计算（1008）编码原始分辨率宏块和较低分辨率宏块的速率失真成本，然后仅在低成本较低分辨率宏块编码（1010）低分辨率宏块。当解码器接收（1104）较低分辨率残差时，它使用标准预测技术（1106）来恢复较低分辨率的宏块。然后，通过内插编码器剩下的值，将宏块“上采样”（1110）到其原始分辨率。然后将宏块连接（1114）以形成原始数字图像。

摘要： Image or video processing methods and apparatuses comprise receiving input data associated with a current picture or a current slice in the current picture, determining whether the current picture is a monochrome picture, conditionally signaling or parsing chroma deblocking parameters depending on whether the current picture is a monochrome picture, and encode or decode the current picture or current slice. The chroma deblocking parameters are used in a deblocking filter operation applied to chroma components of the current picture or current slice when the current picture is not a monochrome picture. A syntax element may be used to indicate derivation of chroma deblocking parameters, and based on a value of the syntax element, the chroma deblocking parameters are allowed to be explicitly signaled in or parsed from a syntax structure, or the chroma deblocking parameters are implicitly inferred.

摘要： A video coder that performs entropy coding of a syntax element for partitioning a block of pixels is provided. The video coder receives a current block of pixels of an image. The video coder encodes or decodes the current block of pixels by partitioning the current block of pixels according to a partitioning indicator. The partitioning indicator is entropy coded as a syntax element of a bitstream by using a context model that is selected based on a partitioning structure of the current block of pixels or of a neighboring block of pixels of the current block of pixels.
