Pixelization, Resolution

I’m trying to get a better resolution with this patch- with less pixelization. Any suggestions?

Keep your background_grab the same resolution as your qt.grab. When you put a 320X240 into your jit.op with the 640X480, you’ll still have 640X480 overall, but the lower-res one will make things look more pixelated. Also the output window should match 640X480, or at least be exactly half—the one you have is 381 X 282, which itself will make things look more pixelated (even though the content isn’t).

Hi, no sure if this will help you, but have a the cv.jit.canny object, which can be downloaded here

This seems to be better, but is it something I missed?

Thank!

so what exactly is the problem? if you want a higher resolution you have to increase the dim attribute.

Dim attribute.

Thanks!
