gaborfilter.tar
- Gabor滤波器经常被用于形状检测和特征提取,比如增强指纹图像。本代码用matlab实现了一个二维Gabor滤波器。 代码使用如下: function [G,gabout] = gaborfilter1(I,Sx,Sy,f,theta) from gaborfilter1 with different f(Frequency) and theta(Angle). for example f:0,2,4,8,16,32 theta = 0,pi/3,pi/6
TRANSFORMEE-HOUGH-DETECTION-DROITES
- This program helps to better understand how the Hough transform. This transform can swap the space of representation. A point in space (X, Y) will become sinusoidal in space (R, Theta) and conversely a point in the plane (R, Theta) will be a line i
dir2dgauss
- Write a function as below which computes a directional first order derivative of 2D Gaussian function: h=dir2dgauss(M, sigma1, N, sigma2, theta).The kernel h is going to have a size of M x N and theta is the angle that the detector is rotated (counte
Gaussian-filter
- Gaussian Filter with example The functions used in the main.m file Function d2gauss.m: This function returns a 2D Gaussian filter with size n1*n2 theta is the angle that the filter rotated counter clockwise and sigma1 and sigma2 are the
