Suppresses the noise on the image by median filtering, large radius results in more smoothed and blurred image. This effect can also be used to create cartoon-like images.
Take care of using large radii: the run-time will increase too!
- Radius: radius of the filter, larger radius results in smoother image.
- Tone: tone of the resulting image, lower tone results in enhancement of darker colors.
The original Tihany (Hungary) image:
By filtering it by a radius of 5 and tone of 50 the image is smoothed:
To enhance the darker regions more, for example at the small windows, decrease the tone to 25:
By increasing the radius to 8 the result is a smoother image:
This filter can also be used to get a cartoon-like picture. The original Cat image:
After filtering it by a radius of 7 and a tone of 40 the result is the following:
