Gaussian filtering is a lot of Image ProcessingAlgorithmIt is of great significance to implement the quick Gaussian filter algorithm through the most crucial intermediate step.
By reading previous documents about the Gaussian filter fast algorithm, we have achieved our own rapid Gaussian filter algorithm, which is nearly six times faster with the neon command.
