Abstract
A method of reading animal identification marks is described. Starting with a series of image frames of an animal, the location and angle of the animal is determined, then the curvature of the animal tail. Using modified frames with a straightened tail, character areas are identified. For a given output character set of a number encoding method, the probability is computed for each character in the set, of that character in each character area, for each frame. The probabilities for the character set for each character area are summed over the frames. Then, the most probable character is chosen for each character area. The chosen characters are combined into a number and verified as being a currently valid animal ID. If the number is not valid, a next most probable character is chosen. This method may be applied separately for a human-readable marking and a machine-readable marking, both on one animal.
