Lost in Compression: the Impact of Lossy Image Compression on Variable Size Object Detection within Infrared Imagery

no code implementations16 May 2022 Neelanjan Bhowmik, Jack W. Barker, Yona Falinie A. Gaus, Toby P. Breckon

When training and evaluating on uncompressed data as a baseline, we achieve maximal mean Average Precision (mAP) of 0. 823 with Cascade R-CNN across the FLIR dataset, outperforming prior work.
