In the process of image processing and storage optimization, the JPEG compression ratio directly affects image quality and file size. This example demonstrates the implementation of JPEG image compression, intuitively presenting the relationship between image effects and file sizes at different compression ratios. 1. Code %% JPEG compression processing with different quality ratios im = … Read more
Image color modes correspond to various color spaces, and the conversion and analysis of color spaces are crucial. This example demonstrates various color space conversions and related image processing operations. Estimated reading time: 5 minutes. 1. Code %% rgbcubergbcube;rgbcube(10,10,10); %% colorcloudrgb=imread('peppers.png');colorcloud(rgb,'rgb');pause;colorcloud(rgb,'lab'); %% RGB color channelsim1=imread('Fig0617.tif');im1=im2double(im1); [m,n,q]=size(im1);[R,G,B]=imsplit(im1); figure,set(gcf,'outerposition',get(0,'screensize'));set(gcf,'NumberTitle','off','Name','Change Channels to Observe Image');subplot(2,2,1),imshow(im1),title('Original Image');subplot(2,2,2),imshow(cat(3,R*0.5,G,B)),title('R Channel Halved');subplot(2,2,3),imshow(cat(3,R,G*2,B)),title('G Channel … Read more
