摘要： The invention is related to a method for determining a filter for interpolating one or more pixels comprised in a frame. The proposed method comprises the step of determining the filter based on other pixels in the remainder of the frame wherein a motion vector associated with said pixels has at least one motion parameter in common with another motion vector associated with said other pixels and the filter is determined such that a quality of an interpolation of said other pixels, said interpolation being determined by help of said determined filter, reaches or exceeds the quality of any other interpolation of said other pixels determinable by help of one of different filter candidates comprised in a filter candidate set. In determining the filter solely on different other pixels of the same frame, said method for determining a filter for interpolation allows for realization of a single pass encoding framework.

摘要： A wavelet transform (WT) is applied to a data stream of high definition video frames, each comprising one or more data channels digitally representing the same image. A WT is applied to each channel. Visual-quality preserving data filters and data substitution techniques are selectively applied that typically lead to at least 90-to-1 compression of the final encoded video frame. Image edge data is extracted and preserved and image noise is reduced to enhance compressibility. After the first WT, primarily low frequency (LL) image data is retained. With each later WT, more non-LL data is retained. Temporal sequences of LL images that result from the final iteration of the wavelet transform are compressed by means of a chain of invertible differenced images. Any color space can be used. Cross-channel conditional substitution is applicable. Complete multiresolution scalability is incorporated into the encoded product. Extra-high definition video encoding is also achievable.
摘要翻译：将小波变换（WT）应用于高分辨率视频帧的数据流，每个数据流包括数字地表示相同图像的一个或多个数据通道。 WT应用于每个通道。选择性地应用视觉质量保留数据滤波器和数据替代技术，其通常导致最终编码视频帧的至少90对1的压缩。提取和保留图像边缘数据，减少图像噪声以增强压缩性。在第一个WT之后，主要是低频（LL）图像数据被保留。随着每个随后的WT，更多的非LL数据被保留。通过小波变换的最终迭代产生的LL图像的时间序列通过可逆差分图像链进行压缩。可以使用任何颜色空间。跨渠道条件替代适用。完整的多分辨率可扩展性被并入编码产品中。超高清视频编码也是可以实现的。

摘要： The present disclosure relates to an apparatus and method for determining an adaptive filter tap to encode a wavelet transform coefficient, a wavelet transform apparatus and a method using the same, and a recording medium for the same, wherein the filter tap is determined rendering the high-band energy to be minimized, based not only on whether an edge is present but also on the edge location so as to adaptively determine the filter tap for an efficient coding of the wavelet transform coefficient. Therefore, the disclosure is able to prevent ringing artifacts and increase coding efficiency while maintaining clear definition on the edges.

摘要： This disclosure describes techniques useful in the encoding and/or decoding of video data of a video sequence. In general, this disclosure sets forth scanning techniques useful in the context of sub-band coding, which may improve the level of compression that can be achieved by entropy coding following sub-band coding. In one example, a method of encoding video data of a video sequence comprises sub-band encoding the video data to generate a plurality of sub-bands, scanning each of the sub-bands from two-dimensional blocks into one-dimensional vectors based on scan orders defined for each of the sub-bands, and entropy encoding each of the scanned sub-bands.

摘要： An image processing apparatus which re-encodes encoded data, encoded with a pixel block having a predetermined number of pixels as a coding unit, while suppressing degradation of image quality, with a higher compressibility. For this purpose, when an encoded-image-data input unit inputs JPEG encoded data with an 8×8 pixel block as a coding unit, a redundancy estimation unit performs encoding on the encoded data, and sets an encoded data amount obtained by the coding, as a target code amount for a recompressor to perform coding in accordance with JPEG 2000 coding. The inputted encoded data is decompressed by a decompressor, and the recompressor generates encoded data in the previously-determined target code amount. The code amount control is performed by deleting the encoded data in bit planes in an order from a least significant bit plane toward a high-order bit plane.
