Abstract
An apparatus comprising an interface and a processor. The interface may be configured to receive a panoramic video stream from a capture device and present one or more enhanced region of interest video frames to a communication device. The processor may be configured to perform de-warping operations on the panoramic video stream received from the interface, perform video analytics on the de-warped panoramic video stream to select a region of interest, crop the de-warped panoramic video based on the region of interest to generate a region of interest video frame, enhance the region of interest video frame and present the enhanced region of interest video frame to the interface. The de-warping operations may be implemented to correct distortion caused by the capture device. The region of interest may be dynamically selected based on objects detected in response to the video analytics.
