Image segmentation

Image Segmentation

For natural (photographic) images, conversion to a reduced color or a black-and-white palette by brightness threshold usually does not produce the desired vectorization results. In these cases, a better result can be achieved using the image segmentation before vectorizing.

The Segmentation method has two customizable settings:

  • Smoothing factor - manages smoothing of the original image; the greater this value is, the sharpness of the edges and contrast areas will be reduced on the image.
  • Color tolerance - color distance threshold in color (RGB) space. If neigbour segments has colors below threshold it will be merged.
