【Compress-Decompress algrithms】 JPEG_Codec DL : 0: This a JPEG codec with AC/DC Huffman entropy coding, 4:2:0 Sampling, RGB/YCbCr converter. 2D-DCT and Quantization is included in the JPEG_Main. There also a Huffman table list in .txt, two sample testing picture and the bitrate-PSNR , CompressionRatio-bitrate comparison analysis. The main function is JPEG_Main, and the others is sub-main funtion. Last but not least, the total implementation is based on the reference 映像情報メディア学会 ,which is written by 吉田俊之-This is a JPEG codec with AC/DC Huffman entropy coding, 4:2:0 Sampling, RGB/YCbCr converter. 2D-DCT and Quantization is included in the JPEG_Main.

【Special Effects】 Image20160331Quality DL : 0: 测试以下图像信息 1。结构内容（SC） 2。均方误差（MSE） 3。峰值信噪比（PSNR值） 4。归一化互相关（NCC） 5。平均差（AD） 6。最大的差异（MD） 7。归一化绝对误差（NAE）-Image/Picture Quality Measures In this application, different image quality measures are calculated for a distorted image with reference to an original image. To test the application, a set of 20 distorted images is included in this package. The list of Image Quality measures implemented in this package include, 1. Structural Content (SC) 2. Mean Square Error (MSE) 3. Peak Signal to Noise Ratio (PSNR in dB) 4. Normalized Cross-Correlation (NCC) 5. Average Difference (AD) 6. Maximum Difference (MD) 7. Normalized Absolute Error (NAE) Refer Reference.png for the mathematical expressions implemented in this package. Original images are kept in the folder OriginalImages . Distorted images are kept in the folder DistortedImages .
