DETECT SPORTS VIDEO HIGHLIGHTS FOR MOBILE COMPUTING DEVICES
First Claim
1. A computer-implemented method for detecting highlights in a sports video at a mobile computing device, comprising:
- receiving a sports video having a plurality of video frames at the mobile computing device;
buffering a segment of the sports video, the segment comprising a plurality of video frames of the sports video;
for each buffered video frame of the sports video;
extracting a plurality of visual features of the video frame;
detecting a highlight in the video frame based on the extracted visual features of the video frame; and
generating a video highlight score for the video frame based on the detection.

Abstract
A solution is provided for detecting in real time video highlights in a sports video at a mobile computing device. A highlight detection module of the mobile computing device extracts visual features from each video frame of the sports video using a trained feature model and detects a highlight in the video frame based on the extracted visual features of the video frame using a trained detection model. The feature model and detection model are trained with a convolutional neural network on a large corpus of videos to generate category level and pair-wise frame feature vectors. Based on the detection, the highlight detection module generates a highlight score for each video frame of the sports video and presents the highlight scores to users of the computing device. The feature model and detection model are dynamically updated based on the real time highlight detection data collected by the mobile computing device.
