I have MATLAB code to read raw data and I can display it using 'uint16' like this:

image with using unsigned integer 16

But when I try to change 'uint16' to 'uint64' I get this:

image with using unsigned integer 64

I want to display my image like the 16bit image with using 64bit. Is there a way to do that? My code is here:

clear all;
I=fopen('data.raw');
A=fread(I,[2048 1536],'uint16');

imagesc(A.');
newmap = contrast(A);
colormap(newmap)

Ask yourself why do I want to use 64-bit ? A color is generally RGB888, 8-bits per components ... you can read the image in uint16 and then use this data in 64-bit floating point (double) format ... is that what you are trying to do ?

  • because i chose the data type as unsigned 64 in ENVI. so i want to compare both images in same conditions. sorry if i couldn't express properly but the point is i get very high quality image with ENVI but when i display in matlab with uint16 the image's quality is too bad. i thought that i can get the same good image with Matlab too. – user9523800 May 28 '18 at 04:40
