I have the same issue using multiple cameras connected to a USB3.0 hub. If I use independent USB ports it just works but

2016-04-12 11:41:33 -0600 asked a question Harris Corner Detector mismatch of border types

I noticed that the Harris corner and MinEigenVal corner detector implementations use the same border mode for both the image and the derivatives. It is possible to specify border REPLICATE for the Sobel calculation in extractCovData while the same border type is used in the corner algorithm. It seems odd to me that we replicate the derivatives on the borders. The right solution for using a second degree accuracy approximation for the first derivative and border replicate should be to use border constant 0 for the derivatives.

Any thoughts or justification of why are we doing this?
