图像的哈弗曼编码matlab实现，实现图像的无损压缩(Matlab coding huffman images achieved)

一个matlab的扩展程序包，可以生成、处理海浪数据得到海浪谱、有效波高、周期等一系列海洋信息的程序。对从事海浪方面的工作者非常有帮助，并且附有使用说明书。功能异常强大，有兴趣的自己慢慢研究。(DIrectional WAve SPectra Toolbox Version 1.4 For MATLAB.DIWASP was originally developed at the Coastal Oceanography Group, Centre for Water Research, University of Western Australia, Perth. It is now distributed and maintained by MetOcean Solutions Ltd., New Zealand.)

混沌粒子群算法用于图像分割，程序已调试好，并用多种图像提供使用。分割效果显著。(Chaotic particle swarm optimization algorithm for image segmentation, the program has been debugged, and use a variety of images available. Segmentation effect is remarkable.)

lz77编码，从文件读取，进行编码，最终以二进制的形式输出到文本。无延伸(lz77 encoding read from the file, encoded in binary form the final output to the text. No extension)

梯度下降法是一個一階最佳化算法，通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值，必須向函數上當前點對應梯度（或者是近似梯度）的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索，則會接近函數的局部極大值點；這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)

KL变换的matlab代码，KL变换是图像正交变换的一种，在图像压缩领域有着广泛应用。很有用哦(KL transform matlab code, KL transform is a kind of orthogonal transformation image in the field of image compression have broad application. Oh, very useful)
