I am using the imwrite function as imwrite(newh,'F:\preeti code\Barba​raTUF2.jpg​','Quality​',100,'Mod​e','lossle​ss'); after this image is generated by my code. It writes a blank white image.But I can see the original image .I have reinstalled MatlabToo

I am using Matlab 2013. File size after imwrite is 2Kb whereas earlier I used to get 32Kb image size. Changed Image Viewer too. Also checked on Matlab 2017 also. Same issue. What could be the problem?

share the newh? What is newh? Its an original image or resultant image?

its an image again

Have you checked the newh by using imshow? blank white image or some resultant image?

OR Try using as following- to find the issue, where the problem is.

destination='D:\Kalyan Works\Matlab Work\folder_name\file_name';
imwrite(result,[destination,'.jpg']);

Often when images show up as white the cause is a conversion to double without rescaling the value. You can check this by running the following code and reporting what the output is.

fprintf('Size is '),fprintf('%d,',size(newh),fprintf('\n')
fprintf('Class is: %s\n',class(newh))
fprintf('Values range from %.1f to %.1f (mean %.1f)\n',min(newh(:)),max(newh(:),mean(newh(:))
