霍夫曼图像压缩编码，无损压缩，压缩率为2倍，压缩效果很好。(Image compression Huffman coding, lossless compression, the compression rate is 2 times the compression works well.)

利用matlab对只包含RBG三个波段的图像进行植被提取，通过设定一定的阈值将植被与背景进行分割(The vegetation is extracted from the image containing only three bands of rbg by matlab, and the vegetation and background are segmented by setting a certain threshold.)

说明：  拉普拉斯金字塔算法跟代码！分割图像！请下载！(laplace)

图像融合程序，及论文 图像融合程序，及论文 图像融合程序，及论文(Image fusion procedure, and the paper image fusion procedure, and the paper image fusion process, and papers)

一种改进的VIBE运动目标检测算法，属于背景差分法，能对不同环境的目标进行检测，能消除鬼影。(The moving target detection algorithm VIBE belongs to background difference method. It can detect objects in different environments and eliminate ghosts.)

提取SIFT特征点，配准拼接的代码，能运行(detect sift features)

本文针对多光谱图像配准中不同光谱图像间存在较大的灰度差异、同一景物在不同波段表现的特征也各不相同等问题，提出了基于互信息相似性测度的多光谱图像配准算法。(In this paper, multi-spectral image registration between different spectral image there is a big difference in gray scale, the same scene in different bands performance characteristics are different questions, we present a similarity measure based on mutual information of multi-spectral image registration algorithm .)

说明：  PCA图像降噪新算法-LPG PCA，全名叫做Two-stage Image Denoising by Principal Component Analysis with Local Pixel Grouping。内含算法代码和数据集，均经本人实测，可进行灰度图像和RGB图像的降噪，且PSNR和SSIM指标明显好于小波滤波、K-SVD等经典算法。值得学习图像降噪的看看！(The new algorithm of PCA image denoising LPG PCA, full name is two stage image denoising by principal component analysis with local pixel grouping. The algorithm code and data set can be used to reduce the noise of gray image and RGB image, and the PSNR and SSIM are better than the classical algorithms such as wavelet filtering and K-SVD. It's worth learning about image denoising!)

本程序实现了基于梯度金字塔的图像融合算法，效果还不错，可以参考一下。(This procedure based on the gradient pyramid implementation of image fusion algorithms, the effect was not bad, you can reference.)

使用DDA划线算法和Bresenham划线算法生成两种不同的直线，并构思图形(Using the DDA scribing algorithm and the Bresenham scribing algorithm, two different straight lines are generated, and the graphics are conceived)
