Missing getStucturingElement and morphologyEx

[xkxx]

Hello,

I'm trying to translate a text classifier that uses morphology algorithms. Uefotunately, they dont seem to be present on node-opencv. Would it be possible to expose these functions?

Thanks,

xkxx

really sad, any news on that?

Just wanted to add that morphologyEx (i.e. opening and closing) as indicated by @kaue as follows:

Closing: const kernel = cv.imgproc.getStructuringElement(2, [eps, eps]); image.dilate(1, kernel); image.erode(1, kernel);

Opening: const kernel = cv.imgproc.getStructuringElement(2, [eps, eps]); image.erode(1, kernel); image.dilate(1, kernel);

Note for the docs about iterations from the docs

The number of iterations is the number of times erosion or dilatation operation will be applied. For instance, an opening operation (MORPH_OPEN) with two iterations is equivalent to apply successively: erode -> erode -> dilate -> dilate (and not erode -> dilate -> erode -> dilate).

Thanks @kaue
