dm642上的图像压缩和解压缩源程序，包括网络、编码和解码部分(DM642 image compression and decompression source, including networks, encoding and decoding part)

说明：  利用PCA对人脸图像进行降维，然后训练神经网络分类器的Matlab程序(the Matlab in face recoginization using PCA algorithm)

用于在图像处理以及计算机视觉中，作为测试的COIL20数据集(The COIL20 data set used as a test in image processing and computer vision)

VC图象处理电子书，Chm格式，基本与位图相关的都作了说明，很不错(VC image processing e-books, Chm format, and basic bitmap were made related to the note, a very good)

JPEG2000图像压缩算法，可计算压缩比，MSE，PSNR等参数(JPEG2000 image compression algorithm, you can calculate the compression ratio, MSE, PSNR and other parameters)

基于最优条件下三次B样条小波的多尺度边缘检测算子(Based on the optimal conditions of cubic B spline wavelet multi-scale edge detection operator)

线性反投影算法（Linear Back Projection，简称 LBP）又称累加法，是最早使用的一种简单（ECT图像重建）成像算法。它将通过某点的所有投影射线进行累加，再反向估算出该点的密度值。从成像观点分析，它是不完全的雷登逆变换（完整的雷登逆变换包括微分、希尔伯特变换、反投影和归一化等步骤）。(Linear back projection algorithm (Linear Back Projection, referred LBP), also known as cumulative method, is the first to use a simple (ECT image reconstruction) imaging algorithms. It accumulates all projection rays through a point, then reverse the estimated density value of the point. From the image point of view analysis, it is not exactly the inverse transform Leiden (Leyden complete inverse transformation involving differential Hilbert transform backprojection and normalization steps, etc.).)

凑算式 看这个算式： ☆☆☆ + ☆☆☆ = ☆☆☆ 如果每个五角星代表 1 ~ 9 的不同的数字。 这个算式有多少种可能的正确填写方法？ (Minato formula Look at this formula: ☆☆☆+ ☆☆☆ = ☆☆☆ If each five-pointed star represents a different number 1 to 9. This formula has a number of possible methods correctly filled?)

基于阈值分割的运动车辆检测跟踪，在视频中按灰度阈值不同进行图像分割，并标记结果。(Threshold-based segmentation to track the movement of vehicles detected in the video by a different gray level threshold for image segmentation, and mark the results.)

说明：  完整的lbp编码，可以学会怎样使用lbp(Complete lbp coding, you can learn how to use the lbp)
