advice for face morph about learnopencv

[leoneckert]

I tried to hack together a solution by adding a 127 grey line to the masks, but that's not a good solution....

am I likely to have a rounding error somewhere? int vs float? I tried everything :D

[leoneckert]

:D :D i am glad you didn't reply yet, found the error myself and feeling oh so good.
it was a typo that I could only find after understanding everything about masks that I didn't understand before -- I learned a lot. thanks and sorry for the many messages here!

No problem! Glad that you figured it out yourself. I am traveling and so was not able to get back to you.

@leoneckert can you post what the problem/solution was? I am also having the same issue and I'd like to know how you fixed it. 😫

[leoneckert]

@conradhappeliv I find it hard to believe you would do the exact same mistake, but as far as I remember I just mixed up one of the operators in the line below, using a "+" instead of a "*" in one spot...

# Copy triangular region of the rectangular patch to the output image
img[r[1]:r[1]+r[3], r[0]:r[0]+r[2]] = img[r[1]:r[1]+r[3], r[0]:r[0]+r[2]] * ( 1 - mask ) + imgRect * mask

same problem?

@leoneckert Finally figured it out! It was similar but not the same. You were right that the masks were overlapping by a pixel. I just set each mask to 0 wherever image data was already in the output.
