Please add seamlessClone do openCV.js

[trsh]

In mean while are there some alternatives?

i want to work on this

[nirinsanity]

I tried building a custom opencv.js build by adding 'seamlessClone' to the opencv_js.config.py file and was able to get the seamlessClone method available in the browser. However, it does not work as expected.

For the sake of simplicity, all the images I used are of the same dimensions. These are the images:
Source

Target

Mask

This is the command I used:
cv.seamlessClone(source, target, mask, new cv.Point(215, 63), dest, cv.NORMAL_CLONE)

And these are the destination outputs I got:

From OpenCV C++ cloning_demo.cpp (✔️ correct)

From my custom built opencv.js with seamlessClone (❌ incorrect)

I'm not sure if I've gone wrong somewhere. If someone can help me, I'd be eternally grateful.

I think NORMAL_CLONE does not work the way it works in CPP or Python. Try with MONOCHROME_TRANSFER.
Please try below one and update further.

cv.seamlessClone(source, target, mask, new cv.Point(215, 63), dest, cv.MONOCHROME_TRANSFER)
