GPUImage Denoise an Image #2236

Closed Vnunev closed 8 years ago

Vnunev commented 8 years ago

Hello guys,

Is there a way to remove the noise of a static image using GPUImage?

Thank you

There are many denoising techniques out there, providing different tradeoffs between image quality and denoising level. You may need to implement your own, but things like the median filter or the bilateral blur have been used in denoising of static images.
