摘要Two enhancement algorithms, the spatial and spatiotemporal homomorphic filtering (SHF and STHF), were proposed in (Highnam, R., Brady, M., 1997. IEEE Trans. Pattern Anal. Machine Intell. 19, 410-415) to enhance far infrared images based upon a far infrared imaging model. In this paper, we theoretically and experimentally prove that the enhanced results with SHF are in general smoother than those with STHF, although STHF may reduce the processing time greatly in comparison to SHF. Based on this conclusion, an adaptive spatiotemporal homomorphic filtering (ASTHF) algorithm is proposed. The adaptive factor of ASTHF is also discussed in detail to obtain the trade off between smoothness and convergence time. (C) 2000 Elsevier Science B.V. All rights reserved.
