DCTJPEG

  使用Matlab编程实现发送端信源编码（图像压缩）和接收端信源解码（图像重建），其中的编解码算法可采用基于DCT变换的JPEG图像压缩标准；测试图像加噪，然后对去噪后的图像进行压缩与重建，分析压缩性能；研究基于下采样和内插的图像压缩算法；可将8bit/pixel灰度图像扩展至24bit/pixel彩色图像，或者采用无损压缩算法对图像压缩。(Sender using the Matlab programming source coding (image compression) and the receiver source decoding (image reconstruction), one of the decoding algorithm can be used DCT-based JPEG image compression standard test image with noise, then the denoised image compression and reconstruction, compression performance analysis of down-sampling and interpolation based on image compression algorithm 8bit/pixel grayscale images can be extended to 24bit/pixel color images, or the use of lossless compression algorithms for image compression. )
