  • System of a video frame detector for video content identification and method thereof
    Patent number: 10607098
    Abstract: A key frame detector and method having input interface accepting multiple frames including a previous frame and a current frame, a programmable logic chip coupled to the input interface that receives a background frame, determines a similarity based on a comparison of the current frame with the background frame and discards the current frame if the similarity is greater than a predetermined similarity threshold, determines an absolute difference on a pixel by pixel basis between the current frame and the previous frame and discards the current frame if the absolute difference is less than a predetermined absolute difference threshold, determines a wholeness of an object in the current frame and discards the current frame if the object is not whole, determines whether the current frame with the whole object has been previously provisionally selected and discards if it has and analyzes the Whole object via an object detector.
