20120044348 | METHOD OF SELECTING AN OPTIMAL VIEWING ANGLE POSITION FOR A CAMERA - This invention relates to a method of selecting an optimal viewing angle position for a camera. A first quantitative score is determined for a first viewing angle position of the camera using pre-selected regions of interest as reference areas, the determining being performed in accordance to a pre-defined quantitative score rule. The angle position is adjusted from the first viewing angle position towards at least one second viewing angle position. For each at least one second viewing angle position a second quantitative score is determined in accordance to the pre-defined quantitative score rule, and finally a target viewing angle position is determined based on the determined quantitative scores. | 02-23-2012 |

20130293783 | MOTION VECTOR BASED COMPARISON OF MOVING OBJECTS - The present invention proposes to analyze movements of objects in video sequences (e.g. sport videos), by performing motion estimation to determine motion vectors at each frame. With the calculated motion vectors, the movements of the object(s) (e.g. athlete(s)) can be quantitatively measured. Based on this, movements in two videos can be compared at each individual frame of the video sequence. Different approaches (e.g., color coding) can be used to visualize and compare the movements. With motion estimation, intermediate frames can also be inserted to enable better movement comparison in two given videos. | 11-07-2013 |
