[Scilab-users] IPCV upscaling of image

[P M]

Dear Claus,

you need to feed a list into imsuperres()....not directly the image.
Following should work.

imgList = list();imgList(1) = imread('path_to_image');imgOut  =
imsuperres(imgList);
figure();imshow(imgList(1));figure();imshow(imgOut);

Philipp
