This is my first question here and I'm not a graphic designer, just need to change some 'ground truth', as we call it in computer vision to train a conv. neural net.
There is an image, size HxWx3 and its 'ground truth' mask, HxWx1. Ground truth uses just white (for borders) color delineating some objects. I need to change it a little bit, by adding more white borders.
I need to overlay these two images such that both are visible (i.e. some transparency is necessary) and add these changes to the mask. Then I need to save that mask in a separate file.
Sorry if the question's dumb, but I've looked around and haven't been able to implement anything sensible. These are the images, the former is 1000x600x3, the latter (mask) is 1000x600x1:
The best I could manage is this, and this is nowhere what I want; among other things, I couldn't find the way the use white color to draw.
Any help is appreciated
