OpenCV

System information (version)

• OpenCV => 4.2
• Operating System / Platform => Windows 64 Bit
• Compiler => Visual Studio Code 1.56.2

Detailed description

When running cv2.seamlessClone() the error is a bit misleading when the incorrect image path is supplied. It doesn't make it obvious that the problem is in the path

Steps to reproduce

import cv2
# Read i

• OpenCV =>3.4.3 / 3.4.4
• Operating System / Platform => Windows 64 Bit / ubuntu 16
• Compiler => opencv-contrib-python 3.4.4 / 3.4.3 (from pip)

for unknown reason, sample only runs,
if we use cv.reg_MapShift cv.reg_MapperGradShift and cv.reg_MapperPyramid here:

Stitching API

Opencv provide a Stitching module/API

Bascially, i would like to be able to rewrite stitching_detailed.cpp in javascript

This includes :

• Stitcher class
• Features extractors (already implemented in opencv4nodejs)
• Estimator
