Request for deblurring application #3

Closed rsingh2083 closed 3 years ago

rsingh2083 commented 3 years ago

Dear Sir,

By any chance can you develop a fast and lightweight image de blurring application ? Just a polite request.

Qengineering commented 3 years ago

That's not so easy to do either. The most common way is to use an FFT kernel that describes the desired blur. You need one 2D forward FFT, a convolution phase and a backward FFT. FFTs are usually 2^x sizes (32,64,128 etc.). Other formats requires additional algorithms. As you can imagine, a lightweight solution is not easy to find. Often, the results are also disappointing. Only very well defined blur can be reasonable eliminated.

Thanks for the suggestions sir
