Target detection on a high resolution midwave infrared focal plane array is cost prohibitive in some applications. But, due to the compressibility of infrared image patches, the high resolution requirement could be reduced with target detection capability preserved. As the most probable coefficient indices of the support set of the infrared image patches could be learnt from the training data, we develop STLS for MWIR image reconstruction. Using the same measurement matrix as in STLS, we construct CQCF for compressed infrared target detection. Numerical simulations show that the recognition performance of our algorithm matches that of the standard full reconstruction methods but at a fraction of the execution time.
