Description: Recent studies on Mathematical modeling of visual cortical cells [Kulikowski/Marcelja/Bishop:1982] suggest a tuned band pass filter bank structure. These filters are found to have Gaussian transfer functions in the frequency domain. Thus, taking the Inverse Fourier Transform of this transfer function we get a filter characteristics closely resembling to the Gabor filters. The Gabor filter is basically a Gaussian (with variances sx and sy along x and y-axes respectively) modulated by a complex sinusoid (with centre frequencies U and V along x and y-axes respectively).

里面是关于Hough变换的边缘检测的源代码-There is a Hough transform on the source code for edge detection

角点检测： 最简单的一种角点检测算子，但是由于采用了非最大化抑制，效果和OpenCV相当 输入的ImageGray为图像的灰度描述，WBPoint为Boolean数组，ImagePoint为标准角点检测算子运行后的检测值。-Corner Detection: The simplest type of corner detection operator, but due to the non-maximization of inhibition, the effectiveness and OpenCV considerable input ImageGray description for gray-scale images, WBPoint for Boolean array, ImagePoint standard corner detection operator After the detection of sub-run value.

比较五种窗函数特性matlab程序：得到矩形窗、海明窗、三角窗、汉宁窗和布莱克曼窗图形。从仿真结果可知：矩形窗设计的过渡带最窄，但阻带最小衰减也最差。布莱克曼窗设计的阻带最小衰减最好，但过渡带最宽。-Comparison of characteristics of five kinds of window function matlab program: to be a rectangular window, Hamming window, triangular window, Hanning window and Blackman window graphics. From the simulation results we can see: the rectangular window designed for narrow transition zone, but the minimum stop-band attenuation is also the worst. Blackman window design of the stop-band minimum attenuation is best, but the transitional zone widest.
