1D gabor Filter
- Descr iption: Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thu
Affine Transformation02
- The transformation parameters are specified by the user by editing the values of the rotation, scale (x and y), and shear (x and y). The translation is not icluded because it can be easily (normalized or) removed from the image by subtracting t
处理当前屏幕用的一个小程序
- 看pdf等的电子书,白底黑字看时间长了不舒服,想换成其他颜色的 有时候网上看到的图片or网页背景黑糊糊的,保存下来再处理才看得清... 功能: 0.scr ipt自定义处理流程 处理由系统热键触发. 1.双击scr ipt的编辑框显示的提示: Y , y : Yes //写屏 N , n : No 0 : XGrey //Grey 1 : One //取反 2 : Two //二值化 3 : XRGB //RGB亮度调节 4 : XE
Problem2_6
- 使用VB.net编写的对24位位图进行简单图像处理的程序,包括RGB与YIQ数据的相互变换,绘制亮度分布统计图,拉普拉斯滤波。 该程序是我学习图像处理算法是编写的,因此在操作界面方面的考虑较少,你可以按照以下步骤操作:选择一个文件后单击读取BMP文件,然后就可以单击“根据RGB数据绘图”,接着可以单击“RGB to YIQ”将RGB数据转化为YIQ数据,有了YIQ数据后就可以单击“绘制YIQ数据的Y分量”,对于YIQ数据,可以使用拉普拉斯滤波,然后再将Y分量显示出来-use VB.net p

yuv_ratio
- YUV图像中修改Y值的程序. 在这里YUV的格式是先YYYYYYYYYY..然后UUUUUUUUUU...然后VVVVVVVVV... 不是YUVYUVYUVYUV这个格式。运行的时候把YUV格式的图片放到C目录下。-YUV images Y value of the revised procedures. Here YUV format is first YYYYYYYYYY. . UUUUUUUUUU then ... then ... not YUVYUVYU VVVVVVVVV VY
read_yuv
- 自己写的用matlab读取YUV文件,并分帧保存.生成一个N维矩阵(N是总帧数),一维就是一帧的数据. Y U V分别保存.-wrote it myself using Matlab YUV read documents, preservation and framing. Generating an N-dimensional matrix (N is the total frame count). is a one-dimensional data. Y U V were preserv
imagescaler
- 8位或者24位图像缩放模块,支持X、Y方向不等比例的任意倍,甚至非整倍缩放功能,支持插值功能-eight or 24 images zoom module, support X, Y directions ratio ranging from the arbitrary times, even aneuploidy zoom function, support interpolation function
ColorTransformRGB-LAB
- 自己写的很实用的色彩空间转换程序: 在色彩空间的正向转换中(RGB----->Lab),用的是九级均匀分割建模 在色彩空间的反向转换中(Lab----->RGB),用的是多项式(20项)回归的方法! 二十项多项式: p(x,y,z)=a0+a1*x+a2*y+a3*z+a4*x*y+a5*y*z+a6*x*z+a7*x^2+a8*y^2+a9*z^2+a10*x*y*z+a11*x^3+a12*y^3-himself wrote a very practical c

Graphics
- 一个集成的图形界面的程序,可调用每一次作业子程序。一、调用画点的函数,用DDA、中点算法画直线和中点算法画圆和椭圆。二、多边形扫描转换算法和区域填充算法实现(扫描线算法为必做,基于求余运算的边缘填充和边标志算法为任选;基于种子的区域填充采用4连通区域的递归种子填充算法,或扫描线种子填充算法,要求种子点(x,y)可交互输入)。三、线段裁剪和多边形裁剪算法的动画演示实现。(两种线段裁剪算法和H-S多边形逐边裁剪算法)多边形裁剪算法的动画演示要求先画出一个封闭的多边形,再画矩形的裁剪窗口,然后选择裁剪
