  抖动矩阵
     Principle of this method is to build basic pattern matrix sequence by Bayer dispersed-dot ordered dither matrix in the first place and afterwards image scrambling technology based on Arnold transformation is applied to obtain the improved pattern matrix sequence. Thereby the regular pattern artifacts and contouring effects can be removed.
     该方法以Bay-er有序抖动矩阵为基础生成基本模板矩阵序列,并在此基础上使用基于Arnold变换的图像置乱技术,得到改进模板矩阵序列,以消除由该方法产生的规则图案纹理现象和渐变轮廓现象.

It has been proved by theory and experiments that high data compression ratio and good image quality can be obtained by coding the high and low frequency component of the image respectively. The key of this image coding technique is the decomposition of the image into high and low frequency component and the image reconstruction from them. This paper presents a new way of image decomposition-Ordered Dither Matrix Matching that seperates the image into edge blocks and flat blocks. The edge block is processed...

It has been proved by theory and experiments that high data compression ratio and good image quality can be obtained by coding the high and low frequency component of the image respectively. The key of this image coding technique is the decomposition of the image into high and low frequency component and the image reconstruction from them. This paper presents a new way of image decomposition-Ordered Dither Matrix Matching that seperates the image into edge blocks and flat blocks. The edge block is processed by BTC (Block Truncation Coding), while the flat block is represented by its average greyscale. Computer simulation results show that the bit rate for a head-and-shoulder image is 0.701 bit/pel with subjective quality neatly similar to that encoded by BCT at the bit rate of 2 bit/pel.

理论和实验证明:把图象的高频和低频分量分别编码可获得较大的数据压缩比和良好的图象质量。高低频编码的关键技术是高低频分量的分解与综合。本文研究了利用有序抖动(Ordered Dither)矩阵匹配法检测边缘,从而把图象分成边缘子块和均匀子块,较好地解决了上述问题。本文具体介绍了边缘子块的检测算法和一个数据压缩方案,它对边缘子块采用BTC编码,对均匀子块用其子块灰度均值表示。对于有复杂背景的人头象,取得了0.701 bit/pel的结果。

In this paper, a new algorithm for building stochastic clustered dot screens is being proposed. A large dither matrix comprising thousands of stochastically laid out screen dots is constructed by first laying out the screen dot centers. Screen dot centers are obtained by placing discrete disks of a chosen radius at free locations when traversing the dither array cells according to a random space filling curve. After Delaunay triangulation of the screen dot centers, the maximal surface of each screen...

In this paper, a new algorithm for building stochastic clustered dot screens is being proposed. A large dither matrix comprising thousands of stochastically laid out screen dots is constructed by first laying out the screen dot centers. Screen dot centers are obtained by placing discrete disks of a chosen radius at free locations when traversing the dither array cells according to a random space filling curve. After Delaunay triangulation of the screen dot centers, the maximal surface of each screen dot is computed. An array of preliminary threshold values is obtained by dividing each screen dot into 256 iso intensity regions. The final dither threshold array is generated by smoothing the preliminary array. By changing the disk radius, the screen dot size can be adapted to the characteristics of particular printing devices. Experiments show that the proposed stochastic screen generation method is of interest for high resolution printing devices:at 1200dpi, a stochastic screen generated with a disk of radius r =8 corresponds to a traditional screen of 150lpi.

提出了一个构造随机聚合网屏的新算法 .该算法首先构造一个大抖动矩阵 ,随机遍历抖动矩阵的元素 ,在自由元素处放置选定半径的离散圆盘 ,获得网点的中心 ,这样构造出一个由数千个随机放置的网点组成的大抖动矩阵 ,然后对网点中心进行 Delaunay三角化 ,计算出每个网点的最大表面 .再把每个网点划分成 2 5 6份等密度区域 ,得到一个初步的阈值矩阵 .对这个阈值矩阵进行平滑处理 ,可得到最后的抖动矩阵 .通过改变盘子的半径 ,可以使网点的大小能适应特定的印刷设备 .实验证明 ,使用这种方法产生的随机网屏对高分辨率的印刷设备效果显著 ,12 0 0 dpi的打印机用半径 r=8产生的随机网屏 ,相当于 15 0 lpi的传统网屏 .
