8*8矩阵dct变换以及量化 反量化和反dct变换(8* 8 transform and quantization matrix dct quantization and anti-anti-dct transform)

Gaussian Kernel Density Estimation with Bounded Support

光线跟踪，计算机图形学的实验，实现的是消隐，光线之间的遮挡等(Ray-tracing, computer graphics experiments, realize that the hidden light, such as between the block)

冲击滤波模型是用用于图像边缘增强的一种常用算法(Impact filtering model is a commonly used algorithm for image edge enhancement)

这是我做的一个二维傅里叶变换的程序，可以对图像进行2DFFT变换得到频谱图，并利用2DIFFT得到原图像(I do a two-dimensional Fourier transform procedure, 2DFFT transform spectrogram image and utilize 2DIFFT original image)

用差分盒维数处理图像，通过对图像分块，然后每一块来计算该区域的分维数，将其作为该区域所有像素上每一像素的分维数。然后，增强分维数分布图效果，然后取阈值，最后，给人造目标加框。(Differential box counting process the image, the image block, and then every one to calculate the fractal dimension of the region, as all the pixels in the region of each pixel on the fractal dimension. Then enhanced fractal dimension distribution effect, and then take the threshold, and finally, to the man-made objects framed.)

CANNY算子的非极大值抑制步骤，使用插值计算，支持不同的抑制半径(Non-maxima suppression step CANNY Operators using interpolation, support different radii suppression)

一种简单高效地基于压缩感知的跟踪算法。首先利用符合压缩感知RIP条件的随机感知矩对多尺度图像特征进行降维，然后在降维后的特征上采用简单的朴素贝叶斯分类器进行分类。该跟踪算法非常简单，但是实验结果很鲁棒，速度大概能到达40帧/秒(A simple and efficient tracking algorithm based on compressed sensing. Firstly, with the random sensing matrix compressed sensing RIP conditions for multi-scale image feature dimension reduction, and then use the naive Bias classifier simple classification in the feature reduction after the. The tracking algorithm is very simple, but the results are robust, speed can reach 40 frames per second)

DCT水印，简单实用，基于8*8分块的DCT域水印嵌入算法水印图像为64*64(DCT watermark, simple and practical, based on the 8* 8 sub-block DCT domain watermark image watermark embedding algorithm is 64* 64)

图像配准的很好的程序，里面用到粒子群算法(image registration is a good procedure, which used PSO)
