Abstract: A method includes receiving first data defining a first bounding box for a first image of a sequence of images. The first bounding box corresponds to a region of interest including a tracked object. The method also includes receiving object tracking data for a second image of the sequence of images, the object tracking data defining a second bounding box. The second bounding box corresponds to the region of interest including the tracked object in the second image. The method further includes determining a similarity metric for first pixels within the first bounding box and search pixels within each of multiple search bounding boxes. Search coordinates of each of the search bounding boxes correspond to second coordinates of the second bounding box shifted in one or more directions. The method also includes determining a modified second bounding box based on the similarity metric.

Abstract: Described herein are methods, systems, and apparatus to process video images to remove jitteriness due to hand shake. In one aspect, a camera is configured to capture raw video composed of a series of successive image frames of a scene of interest. A processor is configured to receive the image frames, estimate a global camera motion from successive frames, stabilize the camera motion by establishing an upper bound and a lower bound of the global camera motion and smoothing the curve of camera motion between the upper and lower bounds, and upsample the resulting stabilized video frames to produce a smooth video.
