Example
//Input image
CuviImage* gimg = new CuviImage(cuviSize(width,height),depth,1);
gimg->upload(img->imageData,img->widthStep);
//Output Image
CuviImage* gout = new CuviImage(cuviSize(width,height),CUVI_DEPTH_32F,1);
//Compute Eigen Values Using 3x3 Sobel Filter for derivative, and 5x5 window for Eigen Value calculation
cuvi::computerVision::minEigenVals(gimg,gout,CUVI_GRADIENT_SOBEL_3x3,5);
