1. A method of tone mapping high dynamic range images for display on low dynamic range displays comprising the steps of: accessing a high dynamic range image; segmenting the high dynamic range image into different regions such that each region is represented by a matrix, where each element of the matrix is a weight or probability of a pixel; determining or calculating exposure of each region; applying exposure values to the regions responsive to the weight or probability; and fusing the different regions together to obtain a final tone mapped image.
