Description: This zip file contains source code and windows executables for carrying out face detection on a gray scale image. The code implements Viola-Jones adaboosted algorithm for face detection by providing a mex implementation of OpenCV s face detector. Instructions for use and for compiling can be found in the Readme file.
Usage:
FaceDetect (<Haar Cascase XML file>, <Gray scale Image>)
The function returns Nx4 matrix. In case no faces were detected, N=1 and all four entries are -1. Otherwise, N=number of faces in the image and the vector contains the x, y, width and height information of the face.
Example,
A = imread ( lena.jpg , JPG )
Img = double (rgb2gray(A))
Face = FaceDetect( haarcascade_frontalface_alt2.xml ,Img)

Description: Hough变换用来在图象中查找直线。它的原理是：假设有一条与原点距离为s，方向角为θ的一条直线，直线上的每一点都满足方程 s=x*Cosθ+y*Sinθ，利用这个事实，我们可以找出某条直线来。这段程序，用来找出图象中最长的直线。-Hough Transformation is used for searching lines in an image . Here is the principle:
Assume there is a line whoes direction is "sita" , and the distance from the origin to this line is s. So each point in this line satisfies the equation : s=x*Cos(sita)+ y*Sin(sita) . We can find out the lines based on this fact.
And this programme is to find out the longest line in the image.

Description: 已知图象4点坐标和转换后图像相对应4点坐标， 利用openCV求出homograghy 3x3 矩阵， 然后输出变换后图像-There is an input image called "warpin". The goal is to warp this image so that the tiles are approximately square, that is the camera is rotated to look down, which produces an image called warpout, also on the web site. I have measured the corners of the four points necessary to do the warp. They are:
From x,y To x,y
Top Left 75,169 => 103, 19
Top Right 118,165 => 192, 19
Bottom Left 62,222 => 105, 205
Bottom Right 148,216 => 192, 205
The origin of the image is in the top left corner. This is an OpenCV program that takes the warpin image, and using these given transformation coordinates produces the warpout image.

Description:
This project for OpenCV C++.
This is the most commonly used smoothing method.
This is also used to eliminate noises in an image. Gaussian kernel is slided across the image to produce the smoothed image.
Size of the kernel and the standard deviation of the Gaussian distribution in X and Y direction should be chosen carefully.

Description: opencv实现傅里叶变换,傅立叶变换是把图像从空间域转化到频率域的变换。空间域：一般的情况下，空间域的图像是f（x，y）=灰度级（0-255），形象一点就是一个二维矩阵，每个坐标对应一个颜色值。频率域：频率：对于图像来说可以指图像颜色值的梯度，即灰度级的变化速度，幅度：可以简单的理解为是频率的权，即该频率所占的比例：能量=幅度（可能不太准确），变换结果为F（u，v），F代表幅度值，u代表x方向的频率，v代表y方向的频率(Fu Liye transform is the transformation of image from space domain to frequency domain. Spatial domain: in general, the image in the spatial domain is f (x, y) = gray level (0-255), and the image is a two-dimensional matrix, and each coordinate corresponds to a color value. Frequency domain: frequency: for images can refer to gradient image color values, i.e. the rate of change of gray level range can be simply understood as the right that the frequency of the frequency, the proportion of energy (= range may not be accurate), transform results for F (U, V), F on behalf of amplitude values, u represents the direction of X V frequency, Y direction frequency)
