基于帧差法的运动目标检测的matlab代码，先读取avi视频，提取每帧图片，进行目标跟踪。 (Read avi video, extract each frame image, and target tracking)

说明：  自组织神经网络SOM的算法，经过调试可以用(Self-organizing neural network SOM algorithm can be used after debugging)

在matlab环境下，包括图像评价函数算法：Brenner、方差、梯度阈值、熵函数、能量梯度函数。(in Matlab environment, including image evaluation function algorithm : Brenner, variance, gradient threshold, entropy function, energy gradient function.)

在GDAL库下，采用主成分变换实现多光谱影像与全色高分辨影像的融合。(Under the GDAL library, the principal component transformation is used to fuse multispectral images with panchromatic high resolution images.)

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)

读取256色，真彩色图像，分别显示，图像灰度化，二值化，直方图，直方图均衡化(Read 256 colors, true color images were displayed image graying, binarization, histogram, histogram equalization)

该算法可以清楚的将雷达目标检测出来，去除旁瓣遮挡效应，提高雷达目标检测的分辨率。(The algorithm can clear the radar target detection out, remove side lobe barrier effect, to improve the resolution of the radar target detection.)

说明：  基于改进JPEG-LS算法的遥感图像近无损压缩专利，由航天五院508所申报，很详细的介绍了算法和fpga的实现(Improved JPEG-LS algorithm near lossless compression patent, the space the five branches of 508 reporting, a detailed explanation of the algorithm and implementation fpga)
