Waterpixels is a filter based on superpixels and the watershed transformation. These algorithms are used to divide images in regions with similar color values.

These options are described in Section 2, “Common Features”. |
The size of the area used to pick a value from. Larger values means you will get less color regions.
The smoothness of the gradient used in the computation. Higher values have less irregular borders.
Specifies how regular the regions should be. Low values are irregular. The higher the value, the more the regions start looking like squares.
This selects how to choose the color for each region. By default Average is used. Which takes the average color of the pixels in the region. The other option is Random, which uses a random color.
