C处理BMP图像程序，有点缺陷，请大家指出。共同进步(C procedures for handling BMP image, a little flaw, please point out. Common progress)

YUV420视频的缩放，经过高度的优化，其中三次卷积插值（cubic convolution）算法的效果最好，优化程度也最高。其基本思想是通过整型化、查表等方法消除每一帧图像插值运算中的浮点运算和乘除法运算。(scale YUV420 video frames with cubic, bilinear & cubic convolution interpolation algorithms。)

对三帧差法进行改进后的多帧融合差分法，改变原有提取帧的方法(Improved multi-frame to fusion difference method, a change in the original extract frames of three poor law)

说明：  本代码可以载入超声图像，然后通过标注连通区域，自动截取最大连通区域对应的图像部分，达到去除四周标注的目的(After loading the ultrasonic image, the image part can be automatically cut off to remove the surrounding annotation)

说明：  最大熵是图像阈值分割里常用的一种简单且效果明显的方法。该代码是最大熵算法的快速递推形式。(Maximum Entropy is Image Threshold Segmentation ri common a simple and obvious effect method. The code is maximum entropy algorithm rapid recursion forms.)

说明：  实现pca主成分分析算法的c语言代码，希望能帮到大家。(Pca principal component analysis algorithm to achieve the c language code, hope to help you.)

采用形态学进行开闭运算，及纹理等分割方法。(The Methods of Image Segmentation on Application and Analysis of Remote Sensing Images)

基于滤波和BEMD的红外小目标检测算法，检测效果好。(BEMD algorithm is able to estimate the background effectively and get the target image by removing the background from the original image and segmenting the Intrinsic Mode Functions making use of the local inverse entropy.)

根据图的邻接矩阵判断图的连通性并计算图的分块数(To determine the connectivity of the graph and computing graph blocks according to the adjacency matrix)
