Effective Despeckling of HDR Images
Résumé
High Dynamic Range (HDR) images are common in computer graphics. In these images, speckles can appear for various reasons, such as high variance for Monte-Carlo-based rendering engines. These speckles are responsible for large artefacts if non-robust post-processing methods are used, such as tonemapping operators relying on a maximal or average luminance value. Ensuring that all post-processing operators are robust is tedious, therefore we propose to handle these speckles before any other processing is done. This way, we ensure that any HDR image post-processing pipeline produces acceptable results.
