Abstract: To solve the problem of high dynamic range image display on traditional devices, a regionalized non-local means filter is proposed. Together with image appearance model framework, it is used to reconstruct color information and tone mapping. The original non-local means filter was modified by considering region segmentation as a new factor for the weight function. The new filter was employed to decompose an image into base layer and detail layer. The reconstructed image was obtained by several steps including chromatic adaptation, tone compression, detail compensation and adjustment. Experimental results show that the model can preserve details, accurately predict, and restore color information.
