Frequently Asked Questions
Why use median filtering instead of simple gaussian blur?
Gaussian blur destroys sharp contrast boundaries and softens text, whereas median filtering effectively wipes out high-frequency noise spikes while preserving sharp structural edges.
Are large photos supported?
Yes! Processing runs directly in memory with optimized 1D typed arrays for high speed.
