sift
SIFT,即尺度不变特征变换(Scale-invariant feature transform,SIFT),是用于图像处理领域的一种描述。这种描述具有尺度不变性,可在图像中检测出关键点,是一种局部特征描述子。 该方法于 1999 年由 David Lowe 首先发表于计算机视觉国际会议(International Conference on Computer Vision,ICCV),2004 年再次经 David Lowe 整理完善后发表于 International journal of computer vision(IJCV) 。截止 2014 年 8 月,该论文单篇被引次数达 25000 余次。(来自百度)(SIFT, namely Scale-invariant feature transform (SIFT), is a description used in the field of image processing. This description has scale invariance and can detect key points in images. It is a local feature descriptor. This method was first published by David Lowe at the International Conference on Computer Vision (ICCV) in 1999 and published in the International Journal of Computer Vision (IJCV) in 2004 after it was sorted out and perfected by David Lowe again. As of August 2014, more than 25,000 citations have been cited. (From Baidu))

DFT&DCT
编程实现二维8*8图像块的DFT,DCT变换
输入一副RGB图像,将其转化为YCbCr颜色空间,然后对Y分量做分块DFT变换,保存为灰度图像,统计计算时间
编程实现8*8块DCT变换,然后分别显示,当使用64个DCT系数里面的一些系数进行重构,比较其质量;同时熟悉采用FFT来实现DCT变换的思想,并显示2维8*8DCT变换的基函数图像(Programming the DFT, DCT transform of two dimensional 8*8 image block
Input a pair of RGB images, transform it into YCbCr color space, then divide the Y component into block DFT transform, save as gray image, and calculate the calculation time
The 8*8 block DCT transform is implemented by programming, and then it is shown that when using some coefficients in 64 DCT coefficients, the quality is reconstructed. Meanwhile, the idea of DCT transformation is familiar with FFT, and the base function image of the 2 dimensional 8*8DCT transform is displayed.)
