When i run the following code error occured:
Error using imwrite (line 442)
Cannot write signed integer data to a JPEG file.
Error in cnn (line 19)
imwrite( data1, outfile, 'jpg');
data1 is the 512x512 int16.
clc;
clear all;
close all;
dirpath='C:\Users\suraj\Desktop\Tumor\New folder\brainTumorDataPublic_1-766\';
dirpath1='D:\Thesis Work\Thesis Report\jpgdataset\';
type='mat';
type1='jpg';
oldvar = '';
for j=4:9
infile = fullfile(dirpath, sprintf('%d.mat', j));
outfile = fullfile(dirpath1, sprintf('HK%d.jpg', j));
datastruct = load(infile);
fn = fieldnames(datastruct);
firstvar = fn{1};
data = datastruct.(firstvar);
data1 = data.image;
imwrite( data1, outfile);
if ~strcmp(oldvar, firstvar)
fprintf('loading from variable %s as of file %d\n', firstvar);
end
end
