Abstract
A method and system for real-time noise removal and image enhancement of high-dynamic range (HDR) images. The method includes receiving an HDR input image I and operating processing circuitry for (i) applying a first edge-preserving filter (e.g. guided filter) to the input image I, thereby generating a first image component Band a first set of linear coefficients ā; (ii) applying a second edge-preserving filter (e.g. guided filter) to the input image I, thereby generating a second image component Band a second set of linear coefficients ā; (iii) generating a plausibility mask P from a combination of the first set of linear coefficients āand the second set of linear coefficients ā, the plausibility mask P indicating spatial detail within the input image I; and (iv) generating an output image O based on first image component B, the second image component Band the plausibility mask P.
