1. A method for tone mapping high dynamic range images for display on low dynamic range displays comprising the steps of: accessing high dynamic range images; dividing the high dynamic range images 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 value; determining or calculating exposure of each region by estimating an anchor point in 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.
