I had an computer vision application that works with Nvidia VisionWorks. Now that Nvidia replaced VisionWorks with VPI(Vision Programming Interface), I am trying to rewrite my application using VPI. At some point, I realized that Pyramid LK Optical Flow performance is not even close to VisionWorks. I checked the logs and figured out that VPI Optical flow is not as performant but I couldn't find anyone having the same problem. Is my judgement skewed or is there a performance problem on this new product of Nvidia?
