哈夫曼编码,香农

region growing for image segmentation, code by Dkroon

curvelet变换贝叶斯估计方法，用于估计含噪声图像的噪声参数。再对图像进行去噪处理-curvelet transform Bayesian estimation methods used to estimate the image noise with noise parameters. Re-image de-noising processing

用LSB的方法，实现了信息的隐藏和提取。-LSB method used to achieve information hiding and extraction.

uniform noise 噪音 去除源码，利用3阶均值完成

图形格式转换 完成TIF到BMP格式的转换 -TIF graphics format conversion to complete the conversion to BMP format

霍夫曼编码的具体方法：先按出现的概率大小排队，把两个最小的概率相加，作为新的概率 和剩余的概率重新排队，再把最小的两个概率相加，再重新排队，直到最后变成1。每次相 加时都将“0”和“1”赋与相加的两个概率，读出时由该符号开始一直走到最后的“1”， 将路线上所遇到的“0”和“1”按最低位到最高位的顺序排好，就是该符号的霍夫曼编码。-Huffman code specific Methods: according to their probability of emergence of the size of the queues, the two smallest sum probability, as a new probability and the probability of the remaining re-queue, and then the smallest sum of two probabilities, and then re-queue until the last turn into one. Every time when the sum will be

图像的几何变换的相关算法：垂直与水平镜像，图像的缩放与旋转等-Geometric transform correlation algorithm: vertical and horizontal image, image scaling and rotation, etc.

这个是数字图像处理的LOG和DOG边缘检测程序。-This is a digital image processing DOG and LOG edge detection procedure.

能量检测,主要是看如果根据虚警概率得到门限，然后进行判决-enengy detection
