Alibaba’s Technical Solution for Object Detection

When a live stream begins, the live stream is differentiated by the live room ID, after which a specific cache is initiated. In the live streaming process, the bottom-up feature is calculated for the frame corresponding to the ID and is compared with the cache’s contents. Detection result are read directly for matches; for non-matches, the target detection cluster is called in for calculations, the results of which are written synchronously to the cache.
