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. Platform: |
