Abstract
A method and apparatus for detecting a meaningful motion. The method of detecting a meaningful motion includes generating a difference image including a plurality of regions each having a sign according to a motion of an input image from a plurality of input images, and by calculating the amount of motion in the difference image based on the sign of each of the regions of the difference image, detecting a meaningful motion of the input image. According to the method and apparatus, a high detection ratio can be maintained, while a false alarm ratio with regard to meaningless motion can be lowered.
Claims14
A method of detecting a meaningful motion, comprising:
- generating a difference image comprising a plurality of regions each having a sign according to a motion of an input image from a plurality of input images;
