Patent Images
1. An apparatus for encoding video frames, comprising:
- a receiver to receive events from a dynamic vision sensor and a video frame from an image sensor;
a heat map generator to generate a heat map based on the received events;
a region of interest (ROI) map generator to generate a ROI map based on the heat map;
a parameter adjuster to adjust an encoding parameter based on the ROI map; and
a video encoder to encode the video frame using the adjusted parameter.

Abstract
An example apparatus for encoding video frames includes a receiver to receive events from a dynamic vision sensor and a video frame from an image sensor. The apparatus also includes a heat map generator to generate a heat map based on the received events. The apparatus further includes a region of interest (ROI) map generator generate a ROI map based on the heat map. The apparatus includes a parameter adjuster to adjust an encoding parameter based on the ROI map. The apparatus also further includes a video encoder to encode the video frame using the adjusted parameter.
