Patent ID: 11935295
Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGAN
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 11:
12. A machine vision method comprising:
obtaining, by a first processor from an image sensor, frame data of a current frame of the video stream;
determining, by the first processor, frame difference data based on a comparison of the frame data of the current frame and scene cache data for a previous frame of the video stream, the scene cache data being stored in a scene cache for the video stream;
determining, by the first processor, based on the frame difference data, regions of the video stream to be re-sampled at a higher resolution than the frame data;
obtaining, by the first processor from the image sensor, re-sampling data for the determined regions;
updating, by the first processor, the scene cache data based on the obtained frame data and the re-sampling data;
transmitting, by first processor, the re-sampling data to a second processor to update an analysis scene cache for the video stream;
updating, by the second processor, the analysis scene cache in accordance with the transmitted re-sampling data; and
implementing, by an application processor, a machine vision task based on the updated analysis scene cache.
