Re: [Scilab-users] IPCV upscaling of image
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);

[Scilab-users] IPCV upscaling of image
Hi there I have a 4K picture, which I thought I'll try to upscale with the imsuperres in the IPCV toolbox. The code simply looks like this: imagefile = 'D:\Userdata\Claus\Pictures\Think_Global_4K.png'; im = imread(imagefile); imout = imsuperres(im); The file is read and I get the following response: Unsigned Integer 8 bits (2160 x 3840). Then Scilab crashes. I'm running Scilab 6.1.0 (the original release) on Windows 10 - in a MS Windows dialog box I get: >Scilab 6.1.0 (Desktop) has stopped working >A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available. I am not sure that I've understood how to use imsuperres correctly. I see in the _params that rfactor = 4 is the default, so I was expecting the image to be scaled by a factor 4 (maybe that's 2 x 2 = I get an 8K image = 4320 x 7680 pixels). The way I understand the documentation, I don't need to run imsuperres_params if I'm satisified with the defaults.

Re: [Scilab-users] Increasing Scilab default Java heap memory to 512 MB?

I conclude that 512 MB is enough. Otherwise you would not have experienced and reported the issue. Wait, what? I don't see how you conclude 512 is enough? In my case, I set it to 2GB: A patch with this value is submitted for Scilab 6.1.1 @ https://codereview.scilab.org/21650 Cool!
