Harris-affine region detector belongs to the category of feature detection
In the fields of computer vision and image analysis， the Harris-affine region detector belongs to the category of feature detection. Feature detection is a preprocessing step of several algorithms that rely on identifying characteristic points or interest -
MATLAB编写的图像处理软件
MATLAB编写的图像处理集成软件。基本功能，打开显示保存图像（灰度、RBG等），直方图分析与曲线拟合处理，亮度分布曲线（模糊处理），均衡化，高斯、中值等滤波处理，边缘提取（soble、拉普拉斯等算法） -

用小波变换进行图像增强
用小波变换进行图像增强，先对原始图像进行非下采样的小波分解，在对每一层的高频分解系数进行处理，得到变换后的小波系数，再进行小波重构。 -
matlab代码实现小图像去噪
小图像去噪程序。th=sigma*sqrt(2*log10(L*T)) 计算阈值ch=c(1，num(4-i，1):num(4-i，3)+step(4-i)-1) 对各高频系数进行阈值处理chl=length(ch) for j=1:chlif abs(ch(j))>=thch(j)=sign(ch(j))*(abs(ch(j))-2*th/(1+exp(m*(ch(j)^2)))) 阈值处理函数else -

interpolating data from an arbitrary 2D sampling pattern to a uniform grid
Gridding is a method of interpolating data from an arbitrary 2D sampling pattern to a uniform grid. In MRI， this allows rapid image reconstruction. There are numerous publications on MR gridding reconstruction.The tar file includes numerous .m scripts， an -
