Claim 0:
1. A computer-implemented method for detecting objects in a video, comprising:
inputting a video into an interleaved object detection model comprising a first feature extractor network, a second feature extractor network, and a shared memory layer, the video comprising a plurality of frames;
analyzing an initial frame of the video with the first feature extractor network to determine an initialized set of features;
storing the initialized set of features in the shared memory layer; and
for each of one or more subsequent frames of the video:
selecting the first feature extractor network or the second feature extractor network to analyze the subsequent frame;
analyzing the subsequent frame by the selected feature extractor network to determine one or more subsequent features of the subsequent frame;
determining an updated set of features based at least in part on the one or more subsequent features; and
detecting an object in the subsequent frame based at least in part on the updated set of features.
