Abstract: In this paper, we propose a simple but effective tone mapping operator, which can achieve impressive results with low complexity in both the formulation and computation. The key point of our operator is to calculate a scalar matrix by which the input HDR image can be mapped into a displayable LDR image. From the graphical perspective, we can regard the scalar matrix as a guided image, as shown in Figure 1(b). Experimental results show that our algorithm can achieve real-time perceptually pleasing result.
