In this paper we model the process of temporal adaptation of the human visual system to varying luminance conditions. An eye tracker is used to capture the location of an observer’s gaze in a high dynamic range image displayed on the screen. We apply a novel technique of eye tracker data filtering to avoid flickering caused by incorrect gaze estimation. Temporary adaptation luminance is then de...

A method for capturing high intensity dynamic range scenes with a low dynamic range camera consists in taking a series of images with di erent exposure settings and combining these into a single high dynamic range image. The combined image values are found by weighted averaging of values from the di erently exposed images on a per-pixel basis. This paper reviews existing weighting schemes and c...

We consider the problem of developing colour sequences that offer the best dynamic range when used for pseudocolouring. We began with nine colour sequences currently suggested for visualization and informally compared them to discover which was subjectively seen to have the most pleasing visual aesthetic. This comparison indicated that different colour sequences are more appropriate for differe...
