ImagesmoothingContrastEnhancement
- 直方图均衡:原始图的直方图变换为均匀分布的形式,这样就增加了象素灰度值的动态范围从而达到增强对比度的效果 中值滤波:中值滤波属于非线性平滑滤波器,它可以消除噪声又能保护图象的细节-histogram equalization : the original plan to transform the histogram in the form of uniform distribution. This will increase the value of the pixel gray area
1
- 了解了24位BMP图像的相关结构后,就要对24位的BMP图像进行加密,因为BMP 图像是由像素组成,每个像素有三个字节,每个字节有8个二进制位组成,因此,改变最低位将不会影响图像的视觉效果。我们将最低位提取出来与高七位进行关联,利用密钥来进行加密,这样就达到了对文件进行嵌入水印的操作。
pcalda
- 人脸识别的源代码 经典的pca和lda人脸识别 实现的成功率有待改进 好的可以达到70 -Face recognition source code for pca and lda classic face recognition could be improved to achieve a good success rate can reach 70
mfc
- 在窗口中显示出26个英文字母,从左向右字母依次位置提高10个像素单位,并且颜色变为红色,然后回到正常位置。当达到最右端后改变方向,从右向左逐渐变为红色,并且位置依次提高10个像素单位。 -In the window shows the 26 English letters, the letters from left to right, followed by location of units increased by 10 pixels, and the color turns red,

animation
- 用c语言实现艺术清屏。问题的提出:我们在编制程序时,经常要用到清屏处理,如dos下的cls,Turbo C下的clrscr()等都具有清屏功能,但这些均为一般意义的清屏, 并未显示其清屏规律.而有时为了达到清屏的艺术美观,往往对清屏有一些具体要求,如:开幕清屏 闭幕清屏 上清屏 下清屏 中清屏.为此,这里 用C语言编制了几个子函数,用于程序中时,既可达到清屏的目的,有能增加屏幕的艺术美观.-C language arts clear screen. Of the problem: in
