image-compression-with-PCA
说明: 对400幅灰度图像用分块PCA的方法进行压缩,进行通信时只用传输主元和特征向量。其中,pcaxiefangcha.m用于图像压缩,imresume.m用于图像恢复和部分图像的显示,chaweight.m用于绘制特征值比重-主元个数关系图,crdraw.m用于绘制压缩比-主元个数关系图,psnrdraw.m用于绘制总误差PSNR-主元个数关系图,psnrlocation.m用于绘制单幅图像误差PSNR分布图。(On the 400 block with a gray image compression method of PCA, to communicate only the main elements and characteristics of transfer vectors. Which, pcaxiefangcha.m for image compression, imresume.m parts of the image for image restoration and display, chaweight.m characteristic value for the draw weight- the main element number diagram, crdraw.m used to draw the compression ratio- the primary element number diagram, psnrdraw.m used to draw the total number of errors PSNR-principal component diagram, psnrlocation.m PSNR used to draw a single image error distribution.)
