Abstract
A system that selects image frames from a video feed for recognition of objects (such as physical objects, text characters, or the like) within the image frames. The individual frames are selected using robust historical metrics that compare individual metrics of the particular image (such as focus, motion, intensity, etc.) to similar metrics of previous image frames in the video feed. The system will select the image frame for object recognition if the image frame is relatively high quality, that is the image frame is suitable for a later object recognition processing.
