摘要： For encoding of mixed-mode images containing text and continuous-tone content, the pixels in the image that form the text content are detected and separated. Text detection classifies pixels as text or continuous tone content by accumulating pixel counts for groups of contiguous, non-smooth pixels with the same color. Groups whose pixel count exceeds a threshold are classified as text. The text detection technique further reduces classification errors by testing for boundary dimensions and pixel density of the group characteristic of long straight lines or large borders. The text detection technique further searches the neighborhood of groups qualifying as text for pixels of the same color, so as to also detect pixels for isolated text marks like dots, accents or punctuation. The separated text and continuous-tone content can be encoded separately for efficient compression while preserving text quality, and the text again superimposed on the continuous tone content at decompression.
摘要翻译：对于包含文本和连续色调内容的混合模式图像的编码，检测和分离形成文本内容的图像中的像素。文本检测通过为具有相同颜色的连续非平滑像素组累加像素计数来将像素分类为文本或连续色调内容。像素数超过阈值的组被分类为文本。文本检测技术通过测试长直线或大边界特征组的边界尺寸和像素密度，进一步减少分类误差。文本检测技术进一步搜索符合相同颜色的像素的文本的组的邻域，以便还检测像点，重音符或标点符号之类的孤立文本标记的像素。分离的文本和连续色调内容可以单独编码以进行有效压缩，同时保持文本质量，并且文本在解压缩时再次叠加在连续色调内容上。

摘要： The present invention relates to a method compressing image data, more particularly to a method for compressing image data by using characteristic values. At first, input image data are executed by using a pre-processing process of the present invention. The pre-processing process is to use a mathematical calculation method, a filter, or a database to differentiate outlines of objects and to classify different objects of the image data. Then different colors, which are in the outlines of the different objects, are acquired by using a color classifying method and the different colors are used to be different characteristic values of the image data. At last, the different characteristic values are saved individually in a memory to finish the method for compressing image data by classifying colors.

摘要： An digital image input, possibly being either pre-compressed or decompressed, is enhanced; its edges are preserved while any compression artifacts, like blocking and ringing, are simultaneously reduced. The enhancement method enhances images with luminance and chrominance functions, incompletely defined or undefined, on a set of pixels so that the missing information is extrapolated while the image is simultaneously enhanced. The method consists of up to three integrated sub-processes: the image sharpening flow; the de-quantization filtering; and the means of control of the local rate of flow. The image sharpening flow is an iterative nonlinear filtering schema intertwining a local median filter and a suitably chosen linear filter. A local geometric control mechanism allows selective application and adaptation of an algorithm allowing selective removal of local artifacts. De-quantization filtering ensures that the enhancement process does not alter information contained in the image beyond its quantization constraints.

For example, during motion compensation, a video encoder or decoder converts luminance motion vectors into chrominance motion vector having quarter-pixel accuracy. Or, during motion compensation, a video encoder or decoder converts luminance motion vectors into chrominance motion vectors using one of multiple available chrominance motion vector rounding modes.

摘要： The present invention provides a method of supplementing a digital picture with a shorter delay time and less calculations. The padding method is applied to a picture having a great motion, and results in producing a prediction signal with small errors. The present invention also provides an apparatus using the same method. To be more specific about the method, in a digital picture data including picture information indicating an object, a picture is resolved into a plurality of regions adjoining with each other, and each of the insignificant sample value of a region containing the boundary of the object shape is supplemented (padded) by the values obtained from transforming of the significant pixels near to the insignificant pixels.

摘要： A Web-based 3D-image display system that downloads 3D-image files from a Web server and smoothly displays 3D images on a Web browser. The Web-based 3D-image display system is provided with a Web server storing compressed 3D files that have been edited and created based on 3D-scene information extracted from a VRML file or the like, and a 3DA applet for displaying 3D scenes; and a Web browser for displaying the 3D scene. The Web browser requests and downloads the 3D applet from the Web server and requests and downloads the compressed 3D file from the Web server by executing the 3D applet. After downloading and receiving all information, the Web browser continuously displays an interactive 3D scene by executing, independently of the Web server, real-time 3D-rendering and 3D-motion algorithms using the 3D applet.
