  • System and method for animal gait characterization from bottom view using video analysis
    Patent number: 8514236
    Abstract: In general, the present invention is directed to systems and methods for finding the gait parameters of an animal using video. The invention includes a system with a video camera coupled to a computer in which the computer is configured to automatically provide animal segmentation, foot identification, foot tracking, and gait parameter calculation. In a preferred embodiment, the present invention may use a treadmill apparatus with a transparent tread or belt for gait parameter calculation. A camera may be placed directly underneath the transparent tread such that the bottom view of the animal walking or running on the transparent tread is captured by the camera. A tilted mirror may also be placed directly underneath the transparent tread in order to reflect the bottom view images to the side where they are captured by a high-speed camera. Thus, the present invention is capable of automatically monitoring a video image to identify, track and classify the actions of various animals' feet within the image.
