基于 matlab 用主元分析对半导体数据进行处理，进行相似度的匹配(Matlab using principal component analysis based on semiconductor data processing, the similarity matching)

The JPEG compression scheme is divided into the following stages: 1. Transform the image into an optimal color space. 2. Adjust Aspect Ratio 16:9 3. Digitization Scheme 4:2:0. 4. Apply a Discrete Cosine Transform (DCT) to blocks of pixels, thus removing redundant image data. 5. Quantize each block of DCT coefficients using weighting functions optimized for the human eye. 6. Encode the resulting coefficients (image data) using a Huffman variable word-length algorithm to remove redundancies in the coefficients. 7. Byte Stuffing. 8. Header JFIF 9. JPG Data Store
