I try to use opencv.js 'OpenCV: OpenCV.js Tutorials) with call to
cv.estimateAffine2D( srcArray, dstArray, inliers, cv.RANSAC, ...)
First, where can I find the help on calling prototype in JS. It is difficult to find correspondance between prototype in C++ and in JS.
Second, estimateAffine2D accepts argument as InputArray and OutputArray.
How can I create such type (I don’t find them when I use assistance during debug (input cv.xxx to get the list of functions or types))
Do you have a small sample of usage ?
