Abstract
A system and method for tracking a spherical ball is presented. A system includes grayscale conversion logic configured to convert an input image into a grayscale image. Motion detection logic detects motion of the ball in the grayscale image and generates a motion likelihood image output. Template matching logic template matches the input image and generates a template likelihood image output indicating where the ball is in the grayscale image. Color matching logic color matches the ball to the input image and generates a color space likelihood image. Fusion logic produces a final fused likelihood image output based on the motion likelihood image output, template likelihood image output and color space likelihood image output. Ball localization logic generates a ball location value and a confidence based on finding an optimal value in the final fused likelihood image output.
