A selective approach for tone mapping high dynamic range content

Abstract

Large resolution High Dynamic Range (HDR) textures/images are becoming common in computer graphics applications. However, it is still a prohibitive task to perform on them a filtering step such as tone mapping in real-time. We introduce a novel technique called Selective Tone Mapper (STM) for accelerating the tone mapping step on large resolution HDR images. This technique presents an efficient memory usage, when compared with traditional methods, due to the reduced information required to localize the strong contrast areas.
