AmphIdent tries to automatically find the ventral pattern of the newt. Because of the longish form of the animals this task is not trivial, which is why the user mostly has to improve the marking of the pattern.
In order to make the marking process as easy as possible the photos should fulfill some requirements:
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 300x600 pixels. The resolution of the picture then depends on the size of the individual on the photo.
The adjacent photo is ideal. The resolution is 410x870 pixels, the background is relatively bright, and the animal lies almost straight and all spots are easily recognizable.
