how to crop image using opencv
Is there an option to crop the image using OpencvUnity package.I can resize but not crop.Kindly help
It's been a while since I've used OpenCV, but I would think you could just resize the matrix [$$anonymous$$atrix::resize()]. Or, if you don't want it anchored to a particular corner, copy the desired indices to a new matrix.
Shouldn't be too hard. The OpenCVUnity package is essentially bindings to the Java OpenCV library, so what works in the Java library should work in the Unity one.
Rect rectCrop = new Rect(cropCenterX, cropCenterY, cropWidth, cropHeight);
Mat croppedImage = new Mat(originalImage, rectCrop);
Let me know if that worked or not!
@SolomonG Thanks. I worked. Yet my cropped image exceeds the scale factor(x:256,y:256,z:1) of Quad(3d game object in unity). $$anonymous$$y original image(Lena.jpg) size:512x512 and my cropped region size is 35x112. Why the cropped image seems to occupy the full region.
