摘要： In a system where two types of data are to be compressed using hierarchical vector quantization (HVQ), it would be typical for there to be two compression tables, one optimized for each type of data. A boundary between the two types may occur within a block to be compressed. In this case, a third table, optimized for a block having both types of data, is used.

摘要： Printing hints can be efficiently compressed in a system using hierarchical compression (HVQ) by first using HVQ to generate compressed codewords, and then adding the printing hint to the codewords to generate an intermediate form of codeword, before sending this intermediate form to a pattern matching lossless compressor for final compression. Even though the same printing hint may be applied to a number of codewords, the overall compression will be affected very little by the addition of the printing hints since the hints are identical over a large number of codewords in series.
摘要翻译： 打印提示可以在使用分层压缩（HVQ）的系统中被有效地压缩，首先使用HVQ生成压缩码字，然后将打印提示添加到码字以产生中间形式的码字，然后将该中间形式发送到模式匹配 无损压缩机用于最终压缩。 即使可以将相同的打印提示应用于多个代码字，但是通过添加打印提示，总体压缩将受到很小的影响，因为提示在大量的串行码字中是相同的。

摘要： Using hierarchical vector quantization (HVQ) to accomplish rotation in addition to compression and decompression. During the compression step the image is divided into segments and each segment is reduced to a codeword. These codewords are transposed so that the segments will be in rotated order when printed. Then the codewords are decompressed to form segments in which the pixels are in rotated order.
摘要翻译： 使用分层矢量量化（HVQ）除了压缩和解压缩之外还能完成旋转。 在压缩步骤期间，图像被分割成段，并且每个段被缩减为码字。 这些码字被转置，使得在打印时这些段将处于旋转顺序。 然后将码字解压缩以形成其中像素处于旋转顺序的段。

摘要： A compression process of dividing each word to be compressed into least and most significant bits, and applying a different compression ratio to each. If the compression processes are lossy, both parts of the output can also be losslessly compressed before being output. Hierarchical vector quantization can be issued for either lossy compressor.
摘要翻译： 将要压缩的每个字分成最小和最高有效位的压缩处理，并且对每个字节应用不同的压缩比。 如果压缩过程是有损的，输出的两个部分也可以在输出之前被无损压缩。 可以为有损压缩器发出分层矢量量化。

摘要： The present invention is a method and apparatus for logic based resolution conversion of digital images. The invention employs an interlocked area mapping technique to provide one or more resolution converted bit planes of digital image data. The system has particular use in highlight color systems, wherein the highlight color data may be processed separately for each color plane, using the present invention, and then recombined to produce enhanced highlight color output.
