Description: 一种灰度图像的半色调图像生成程序。该程序实现了siggraph 2008 论文Structure aware halftoning中的半色调生成算法。该算法基于目标函数优化，用模拟退火方法生成。
该程序可以读入gif,png,jpg,bmp格式的图片，并自动将彩色图转化为灰度图。生成的半色调图目前只支持png格式的输出。
实现语言为java。 在jre 1.6.0_10上测试正常。-A gray-scale image halftoning image generation process. The program achieved a siggraph 2008 paper in the Structure aware halftoning Halftoning Algorithm. The algorithm is based on the objective function optimization, simulated annealing method used to generate. The program can be read into the gif, png, jpg, bmp format images, and automatically will be converted to grayscale color map. Halftone generated map png format only supports the current output. The realization of the language for java. Jre 1.6.0_10 in the tests are normal.

Description: 里面有8PSK，GMSK的matlab源程序，贡献出来了-I was interested in the theory for 8PSK and came across this m-file written in 1999. It
requires 2 function calls (graymapPSK and grayunmapPSK) which I have
included and must be uncommented(single comments only) and loaded into your workspace.
Remove the function calls from this m-file after you load into your
workspace.
It seems to work well and give valid results for BPSK and QPSK but I have a question
about the setup for 8PSK and the solution for Pseint where Pse=Pseint.
Also, the Gray coding seems different than what I m used to.
Some of you more theoretical minded may have some insight into the theory
behind how Pseint was determined and comment. I don t have the
communications toolbox-blockset and was wondering how it compared with Matlab s
example simulation of 8PSK with Gray coding (in Simulink?)
Each run takes about a minute and the loop iterations are shown in the
command window.
A numerical example of a satellite link is shown using uncoded QPSK

Description: 一个空间点P绕一个中心点C旋转可用接续的三个变换来实现：第1个变换平移点C到坐标系原点位置，第2个变换将点P绕原点旋转，第3个变换平移点C回到其相对于坐标系原点的原始位置。当原始图像点乘以变换矩阵，得到新的图像位置点时，其位置可能不是整数值，该位置的灰度值需要通过灰度插值获得。在不改变输出图像大小的情况下，超出原始图片范围的区域，MATLAB原有函数imrotate的处理方法为将其灰度值全部置零，本文通过取模操作对超出区域进行了另外一种控制方法imrotate_my函数，能够较好的显示出图像旋转的边界变化。
-A space around the center point P C available in three rotating to realize the transformation: the first one translation: C to coordinate transformation, the origin place of 2 transform point P around the rotation, the origin of the three points to the transformation of C translation relative to the original position of axis. When the original image point multiply the transformation matrix, a new image position, the position may not integer, this position gray value by gray interpolation gain needed. No change in the size of the image output circumstance, the area beyond the original image, the original function imrotate MATLAB treatment method for the grey value all zeros, based on beyond the area take mould operation on another control method imrotate_my function, to better show of image rotation boundaries.
