Automatic Recognition of Behavioral Patterns of Rats Using Video Imaging and Statistical Classification

A Posture Recognition System for Rat Cyborg Automated Navigation

“…In the area of rat state recognition, different taxonomies have been used. Most the researches [3,7,8] used "behavior" recognition, some [5] used "posture" classification. The relationship between behavior and posture could be understood in this way: posture is the geometric configuration of the body parts at one instantaneous moment, whereas behavior is a dynamic process which involves the movements of different body parts and could be regarded as the time evolution of postures.…”

“…Previously, automated behavioral assessment was mainly studied in pharmacology and psychology. Bumaa et al first extracted coordinate of the head point, tail base and mass center, then along with several additional features derived from these three points and other features describing the shape of the object, they were used for rat behavior recognition with the help of a Bayes classifier [3] . Rousseau et al used very similar features like Ref.…”

“…Rousseau et al used very similar features like Ref. [3] but instead neural networks were used for behavior classification [4] . Heeren et al used Fourier descriptors of the rat body contours and a neural network to classify postures [5] .…”
