Web3 de abr. de 2024 · The GPU of the Jetson Nano is not the fastest, but it should still excel its CPU by far. I also compared cv::cvtColor with cuda::cvtColor, and the CUDA-version is roughly 5x faster (which is not that much, but still), so the problem really seems to be in the morphology-function. The GPU-load is at about 98% during the kernel execution, which … Web8 de jan. de 2013 · Morphological transformations are some simple operations based on the image shape. It is normally performed on binary images. It needs two inputs, one is our original image, second one is called structuring element or kernel which decides the nature of operation. Two basic morphological operators are Erosion and Dilation. WebThe explanation below belongs to the book Learning OpenCV by Bradski and Kaehler. In the previous tutorial we covered two basic Morphology operations: Erosion. Dilation. Based on these two we can effectuate more sophisticated transformations to our images.
