Description: 数字图像处理实验
根据原图像的直方图，发现背景和目标的分割值大约在130左右，并将灰度图像转为二值图像，分割效果比较理想。
图像处理实验（六）图像压缩与编码
实验目的： 学习JPEG压缩编码
实验内容：
一．实现基本JPEG的压缩和编码分三个步骤：
1． 首先通过DCT变换去除数据冗余；
2． 使用量化表对DCT系数进行量化；
3． 对量化后的系数进行Huffman编码。-digital image processing experiments based on the original image histogram, found background and objectives of the divided about the value of around 130 and two gray-scale image to image, Segmentation more satisfactory results. Image processing experiments (6) Image Compression and Coding of the experiment : Learning JPEG compression coding experiment : one. Basically JPEG compression and coding in three steps : 1. First through DCT remove data redundancy; 2. Using quantitative table right DCT coefficient quantization; 3. Right quantized coefficients of Huffman coding.

Description: 利用霍夫曼编码进行图像压缩处理，此程序为霍夫曼编码的示例(The performance of a Huffman code is a function of the entropy of the signal distribution and therefore can be
highly dependent in the transform domain in which the code is applied. For example, JPEG partitions an image
into blocks of 8x8 pixels and then transforms these with a 2D Discrete Cosine Transform (DCT), similar to a
DFT.)
