该算法实现字母个数的统计,希望对大家有用!()

是关于matlab中GUI程序裁剪程序，提供了多种方法，对于图像处理有很好的补充作用(Is about matlab GUI program in tailoring, offers a variety of methods, for image processing, have very good supplementary function)

matlab加载一个视屏，转化成每帧图片加以保存。(Matlab loads a video screen and translates it into pictures for each frame to be saved.)

一幅大小为256×256的256级灰度图像（每像素8bit） 如果图像的各个像素之间是统计独立的，求该图像的信息熵 -离散无记忆信源 如果图像的各个像素之间不是统计独立的，求该图像的信息熵 -图像像素的概率分布模型(A 256 gray scale image (8bit per pixel) with a size of 256 x 256 If each pixel of the image is statistically independent, the information entropy of the image is calculated Discrete memoryless source If each pixel of the image is not statistically independent, the information entropy of the image is calculated Probability distribution model of image pixels)

说明：  基于DCT域的图像数字水印技术，水印嵌入过程，提取过程，以及嵌入水印的抗干扰性等。(Based on the DCT domain image digital watermark technology, watermark embedding process, extraction process, as well as embedded watermark anti-interference and so on.)

数字图像的渐进式传输，采用掩膜矩阵进行基本层和增强层的划分(Progressive transmission of the digital image, the base layer and enhancement layer is divided by using the mask matrix)

两个掌纹识别的MATLAB程序，非常有用(Are two palmprint identification MATLAB program, very useful)

some fast feature extraction algorithms are addressed for joint retrieval of images compressed in JPEG and JPEG2000 formats. In order to avoid full decoding, three fast algorithms that convert block-based discrete cosine transform (BDCT) into wavelet transform are developed, so that wavelet-based features can be extracted from JPEG images as in JPEG2000 images.

实现了Thien在他的文章《secret image sharing》中提出的（r，n）门限秘密图像分存方案。 (Thien in his article " secret image sharing" (r, n) Door Threshold Secret Image Sharing Scheme.)

SAR SIM 仿真软件，可以参考看看，主要用于SAR雷达的成像仿真(SAR SIM simulation software, can refer to the SAR SIM simulation software, can refer to see)
