Bresenham
- 该程序实现了Bresenham算法画直线，将四个象限的问题通过交换端点的方法合并成一，四象限的问题。再利用sign变量，统一成一个问题。又考虑到斜率<=1，>1，不存在，最终问题分成了三种情况。-The program implements Bresenham algorithm for drawing a straight line, the four quadrants of the problem through the exchange of endpoint methods
image-Fourier-transform-zon
- 以图像中心为原点，调整傅立叶变换图像的四个象限区，即第一和第三象限交换-The origin of image center, adjust the four quadrants of the image Fourier transform zone, the exchange of the first and third quadrant
QUAD_old
- QUAD TREE algorithm. It is a segmentation based image compression algorithm. It is a process of recursively dividing the image into four quadrants. -QUAD TREE algorithm. It is a segmentation based image compression algorithm. It is a process of
fft2dDemo_Simple
- 這一個“慢”，但簡單和兩維FFT的演示可以從這裡下載（包括源）。 演示生成的一維或二維的輸入信號（256或256×256大小），這是顯示在左邊的位圖（8位灰度調色板）。 信號包含一個中心的矩形脈衝（脈衝大小從2到256）。因為輸入的是真實的，FFT的日常工聯會（）產生偏見的頻譜。如果“重排”被選中，零頻率頻譜的中心轉移到從各自的象限交換數據。複雜的結果顯示在正確的位圖，在可能的方式有四種：模塊，相位，實部或虛部。如果“InvFFT”被選中，逆FFT頻譜，結果是恢復輸入信號應用。然而
image-fuliyet-ransform
- 以图像中心为原点，调整傅立叶变换图像的四个象限区，即第一和第三象限交换。已运行成功-The four quadrants, i.e. the center of the image as the origin, the adjustment of the Fourier transform image of the first and third quadrant switching. Has been running successfully
inn
- 基于直方图均衡的图像增强代码，将直方图分为四个象限，按照像素比例进行不同的拉伸，效果较好，特别是对较暗的图片。-Based on the histogram equalization image enhancement code, the histogram is divided into four quadrants, in accordance with the proportion of pixels of different tensile better effect, especial
Linear-interpolation-vb
- 这是VB写的一个直线插补源码，有四个象限的整个代码，代码比较全，对开发都来说是很有用的，而且word文档中有整个代码。-It is written in a linear interpolation VB source, there are four quadrants of the entire code, the code is relatively wide, for the development of both is very useful, but there is the whol

- 这是VB写的一个圆弧插补源码，有四个象限的整个代码，代码比较全，对开发都来说是很有用的，而且word文档中有整个代码。-It is written in a circular interpolation VB source, there are four quadrants of the entire code, the code is relatively wide, for the development of both is very useful, but there is the wh
dft
- 以图像中心为原点，调整傅立叶变换图像的四个象限区，即第一和第三象限交换 第二和第四象限交换-With the image center as the origin, four quadrant regions of the Fu Liye transform image are adjusted, namely the first and the third quadrants exchange the second and the fourth quadrants.
