Abstract: A computer vision processor of a camera generates hyperzooms for persons or vehicles from image frames captured by the camera. The hyperzooms include a first hyperzoom associated with the persons or vehicles. The computer vision processor tracks traffic patterns of the persons or vehicles while obviating network usage by the camera by predicting positions of the persons or vehicles using a Kalman Filter from the first hyperzoom. The persons or vehicles are detected in the second hyperzoom. The positions of the persons or vehicles are updated based on detecting the persons or vehicles in the second hyperzoom. The first hyperzoom is removed from the camera. Tracks of the persons or vehicles are generated based on the updated positions. The second hyperzoom is removed from the camera. Track metadata is generated from the tracks for storing in a key-value database located on a non-transitory computer-readable storage medium of the camera.

Abstract: The present application discloses a pixel driving circuit and a display panel. Before the charging module charges the pixel electrode, the present application releases the voltage of the pixel electrode by means of the discharging electrode. Therefore, it is possible to avoid that the voltage of the pixel electrode is charged to a target value after the residual voltage on the pixel electrode needs to be canceled during charging the pixel electrode by the charging module. As a result, the power consumption of the pixel electrode during the charging/discharging process can be reduced, and the charging/discharging time period of the pixel electrode can be reduced.
