One day One Feature : noise reduction

Krita is also about helping you to improve the quality of your photos. The first things I notice, when I got my numeric camera, was that pictures could be some times very noisy. So I wanted to improve it, and I have implemented two filters in Krita for that purpose : “Simple Noise Reduction” and “Wavelet Noise Reduction”. The first one detects if a pixel is very different from the neighbourghood and if it is, it will replace the pixel by convolving the neighbourhood, the resulting effect is that the image looks a little bit blur. In most case the wavelet noise reducer will give better results, the “Simple noise reducer” should be use, if the noise appears as small peaks on the picture.

The results of both filters can be seen on the following screenshot :
