During the operation of pictures of the Fire-bellied toad the user marks the pattern manually. The following demands are made to the pictures:
Too small resolutions compromise the sharpness of the patterns, too large resolutions lengthen the computation time for marking the pattern.
An optimal photo contains the animal with a resolution of approximately 300x300 pixels. The resolution of the picture then depends on the size of the individual on the photo.
The adjacent photo is ideal. Its resolution is 450x500 pixels. Although the animal does not lie completey vertical it is sufficient. Its extremeties point away from the body and the ventral pattern is easily recognizable.
