基于双线性插值法raw2rgb

clc;

close all;

[filename,pathname]=uigetfile({'*.*','All Files (*.*)'},'Pick a file');
file = strcat(pathname,filename);

% raw图的尺寸
row = 1280;
col = 960;
% 读图 所读raw图为8位
fid=fopen(file, 'r');
Bayer=fread(fid,[row,col],'uint8');
fclose(fid);

imR=Bayer(1:2:row,1:2:col);
imG(1:2:row,:)=Bayer(1:2:row,2:2:col);
imG(2:2:row,:)=Bayer(2:2:row,1:2:col);
imB=Bayer(2:2:row,2:2:col);

%imR=imresize(imR,[1280,960],'bicubic');%双线性
imG=imresize(imG,[640,480],'bicubic');%双线性
%imB=imresize(imB,[1280,960],'bicubic');%双线性

rgb(:,:,1)= uint8(imR');
rgb(:,:,2)= uint8(imG');
rgb(:,:,3)= uint8(imB');
