Thermal-image based video compression systems and methods

Abstract:

A system for capturing a thermal video stream includes a thermal image capture component, such as an IR camera, configured to capture and digitize the thermal video stream having n-bits of data per pixel, a memory configured to store the captured thermal images, and a processor. The processor is configured to select captured thermal images as frames for a video stream and subdivide each captured thermal image into separate m-bit and k-bit image streams. The processor is further configured to compress the m-bit thermal image stream in a video compression format that includes frame and metadata, compress the k-bit image stream using a lossless or substantially lossless compression format, and incorporate the compressed k-bit image stream into the coded m-bit video stream as metadata.
