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).

计算机图形学的编程实践，包括画直线、反走样直线、画圆、 画椭圆、画矩形、画多边形、矩形填充、多边形填充、3D变换、光照、贴图等。-Computer graphics programming practice, including painting a straight line, anti-aliased line, circle, drawing an oval, rectangular painting, painting polygon, rectangle fill, polygon fill, 3D transformation, light, texture and so on.

用于对数字图像的处理，初步调研对数字图像的基本处理方法，用cvi实现图像处理界面及函数。最后针对特殊应用进行试验，给出源程序。-used for digital image processing, preliminary research on the basic digital image processing methods, cvi achieved using image processing and interface functions. Finally special application test, given the source.

These are the codes in "A note on two-dimensional linear discrimant analysis", Pattern Recognition Letter In this paper, we show that the discriminant power of two-dimensional discriminant analysis is not stronger than that of LDA under the assumption that the same dimensionality is considered. In experimental parts, on one hand, we confirm the validity of our claim and show the matrix-based methods are not always better than vector-based methods in the small sample size problem on the other hand, we compare several distance measures when the feature matrices and feature vectors are adopted.

图形图像处理之哈夫曼算法完整（VC编译OK）-Graphics Image Processing of Huffman algorithm complete (VC compiler OK)

本程序实现全变分(Total Variation, TV)的去噪算法，它使用了PDF纠正TV算法中的小问题。该算法可以很好地保留原图边缘信息的同时，去除噪声。-This procedure Variational realize the whole (Total Variation, TV) denoising algorithm, which uses a PDF corrective TV algorithm of small problems. The algorithm is well positioned to retain the image edge information at the same time, to remove noise.
