With the growing popularity of High Dynamic Range Imaging (HDRI), the necessity for advanced tone-mapping techniques has greatly increased. In this thesis, I propose a novel saliency guided edge-preserving tone-mapping method that uses saliency region information of an HDR image as input to a guided filter for base and detail image layer separation. Both high resolution and low resolution saliency maps were used for the performance evaluation of the proposed method. After detail layer enhancement and base layer compression with constant weights, a new edge preserved tone-mapped image was composed by adding the layers back together with saturation and exposure adjustments. The filter operation is faster due to the use of the guided filter, which has O(N) time operation with N number of pixels. Both objective and subjective quality assessment results demonstrated that the proposed method has higher edge and naturalness preserving capability, which is homologous to the Human Visual System (HVS), as compared to other state-of-the-art tone-mapping approaches.

Convex Hull Algorithm

As some images perhaps contain pixels whose individual colors will not be perceived if they are below the spatial threshold of human visual system (HVS), the paper presents a wavelet transform method for color image considering HVS characteristics to reduce the redundant color information and then construct perceived gamut of image (PGI), which will be used for effective image-dependent gamut mapping. Taking into account the Contrast Sensitivity Function (CFS) of HVS model, the color information reduction is implemented in some subbands of the wavelet transform domain. Then the image gamut was visualized using the general convex hull algorithm and the constructed PGI will only indicate the perceived part of color image. We preliminarily establish a method for reliably determining PGI, which is help to developing robust and psycho-visually justified image gamut mapping algorithm in the future.
