摘要： The invention determines the degree of similarity between a target image and each of a plurality of reference images. The measure used for the degree of similarity between images is based on the human perceptive system, so that images that appear to a human to be similar in color have a higher similarity measure than images that appear to a human to be dissimilar in color. Each of the most populous colors of each partition of the target image is associated with a color in a corresponding partition of the reference image that is closest to the target image color. The similarity measure is based on the number of occurrences of each of these associated colors in the corresponding partitions, as well as the color difference between these associated colors. Thus, images that have similar, albeit not identical, colors, will have a higher similarity measure than images that have dissimilar colors. In a preferred embodiment, color difference is determined based upon the CIE luminance-chrorinance color space. Also, in a preferred embodiment, the target image color is quantized into a set of discrete colors that are based upon the predominant colors in the reference images.
摘要翻译：本发明确定目标图像与多个参考图像中的每一个之间的相似度。用于图像之间的相似度的度量是基于人类感知系统，使得对于人类来说似乎与颜色相似的图像具有比人类看起来与颜色不同的图像更高的相似性度量。目标图像的每个分区的人口最多的颜色中的每一个与最接近目标图像颜色的参考图像的对应分区中的颜色相关联。相似性度量基于相应分区中的这些相关联的颜色中的每一个的出现次数以及这些相关联的颜色之间的色差。因此，具有相似但尽管不相同的颜色的图像将具有比具有不同颜色的图像更高的相似性度量。在优选实施例中，基于CIE亮度 - 亮度色空间来确定色差。此外，在优选实施例中，目标图像颜色被量化为基于参考图像中的主要颜色的一组离散颜色。

摘要： There is disclosed an image processing device capable of receiving an image file having a first texture representation in rotation variant format and converting the texture representation to a modified texture representation in a rotation invariant format. The image processing device comprises an image processor for analyzing rotation variant texture parameters in the first texture representation and converting them to 1) rotation invariant texture parameters disposed in circular rings about a selected pixel; or 2)rotation invariant texture parameters disposed along radial lines extending through the selected pixel. In the second embodiment, the image processor can use the angular separation of the radial lines to determine the angular rotation of a rotated version of the image file.

摘要： A method and system for creating authentication signatures for digital images and video frames is provided. The method and system involves partitioning the image into multiple blocks, comparing characteristics from each block and generating data bits based on the comparison. Each block is then broken up into additional blocks and those blocks are compared to create additional signature bits which are combined with the signature sets from the first set of blocks. Each of these new smaller blocks can be further broken up and the procedure can be repeated to provide an authentication signature of desired length.

摘要： A method and apparatus for compressing facsimile documents based on arithmetic coding. A combination of one-dimensional and two-dimensional arithmetic coding is employed to ensure that the effect of a transmission error is not propagated to the whole document. Appropriate contexts for the probabilistic models associated with arithmetic coding for one and two dimensional cases are presented. An error detection scheme to identify the presence of transmission errors is also presented.
