ogniewski-scaler's Issues

On windows, a terminal window is opened when using the plugin

This is not intentional.

optional?

Hi @pannacotta98 .

Can add optional separation of the image into low and high frequencies:

$$I_blur = blur(I, radius) I_high = I - I_blur + 127$$

scale these components individually, then merge them together:

$$I_blur_x = scale(I_blur, x) I_high_x = scale(I_high, x) I_x = I_blur_x + I_high_x - 127$$

Clean up compile instructions for windows

scaling.h ?

Hi @pannacotta98 .

Maybe delete src/scaling.h?
