摘要： Automatic characterization or categorization of portions of an input multispectral image based on a selected reference multispectral image. Sets (e.g., vectors) of radiometric descriptors of pixels of each component of a hierarchical representation of the input multispectral image can be collectively manipulated to obtain a set of radiometric descriptors for the component. Each component can be labeled as a (e.g., relatively) positive or negative instance of at least one reference multispectral image (e.g., mining materials, crops, etc.) through a comparison of the set of radiometric descriptors of the component and a set of radiometric descriptors for the reference multispectral image. Pixels may be labeled (e.g., via color, pattern, etc.) as positive or negative instances of the land use or type of the reference multispectral image in a resultant image based on components within which the pixels are found.
摘要翻译：基于选定的参考多光谱图像对输入多光谱图像的部分进行自动表征或分类。输入多光谱图像的分层表示的每个分量的像素的辐射度描述符的集合（例如矢量）可以被共同操纵以获得用于该分量的一组辐射度描述符。通过比较组件的一组辐射测量描述符和一组参考多光谱图像（例如采矿材料，作物等），每个组件可以被标记为至少一个参考多光谱图像（例如，相对）正面或负面的实例用于参考多光谱图像的辐射测量描述符。基于其中发现像素的分量，可以将像素标记为（例如，经由颜色，图案等）作为土地使用的正面或负面实例或所得图像中的参考多光谱图像的类型。

摘要： A coding strategy efficiently codes intra (macroblocks, regions, pictures, VOP) data. This strategy uses two basis approaches, a Fixed Deinterleaved Transform Coding approach, and an Adaptive Deinterleaved Transform Coding approach. Furthermore, within each approach, two types of coders are developed. One coder operates on an entire picture or VOPs and the other coder operates on small local regions. Using coders and decoders of the present invention, efficient coding at a range of complexities becomes possible, allowing suitable tradeoffs for a variety of applications.

摘要： A method for encoding vertex orientations, also known as normal components, of a 3D mesh model comprises a first clustering of the normal components, determining for each of the first clusters a sphere sector to which most of its elements belong, mapping normal components to a predefined sector, re-clustering the normal components in the predefined sector into second clusters, determining predictors for the second clusters and encoding a normal component by its residual, a reference to its predictor and data indicating which of said mirror mapping operations were performed. A sphere sector is obtained by dividing a sphere into m equal spherical segments and dividing each of said spherical segments into n equal sectors. The first clustering for the sector mapping and the second clustering for predictive coding result in an improved compression ratio.

摘要： An alpha image encoding and decoding scheme is disclosed. In the encoding an alpha image, is decomposed into image blocks (600) comprising multiple image element (610). The blocks (600) are compressed into block representations (700). A block representation (700) comprises at least a color codeword (710), an alpha codeword (720), an alpha modifying codeword (730) and a sequence (740) of alpha modifier indices. The color (710) and alpha (720) codeword (710) are representations of the colors and alpha value of the image elements (610) of the block (600), respectively. The alpha modifying codeword (730) is a representation of a set of multiple alpha modifiers for modifying an alpha value represented by the alpha codeword (720). The index sequence (740) includes an alpha index for each image element (610) in the block (600), where an alpha index identifies one of alpha modifiers in the alpha modifier set.
