Abstract: A first device may perform a first part of a computing graph to extract a feature map from media (e.g., video) data. The first device may buffer the media data and compress the feature map. The first device may then send the compressed feature map to a second device, which may perform a second part of the computing graph (e.g., processing tasks), e.g., to perform object detection or other such tasks. The second device may request at least a portion of the buffered media data when needed, e.g., to improve accuracy of the second part of the computing graph/processing tasks. Thus, the second device may send a request to the first device for the at least portion of the buffered media data, then perform the second part of the computing graph using the buffered media data and the received feature map.
