I am using the ridge detection filter from opencv contrib. This filter uses the eigen values from the Hessian Matrix of the input image using Sobel Derivative. But in the the implementation of the filter, i see:

Mat rootex;
rootex = (sb2xx +  (sb2xy + sb2xy + sb2xy + sb2xy)  - (sbxxyy + sbxxyy) + sb2xy );

But as i compute, it musts be:

Mat rootex;
rootex = (sb2xx +  (sb2xy + sb2xy + sb2xy + sb2xy)  - (sbxxyy + sbxxyy) + sb2yy );

Please check it.

Please report it with an issue at the opencv contrib issue tab, so that it can get fixed. To me it seems you are correct.
