Depth of Field (DoF) is an indispensable feature of photo realistic rendering and photography retouching. In this paper, we propose an image-based rendering technique which can simulate the depth-of-field effect. The proposed technique can render the depth-of-field effect automatically without any interactions. Compared to the ordinary depth-of-field rendering technique, our algorithm is less time-consuming and needs no additional depth maps to assist the depth-of-field rendering. In our proposed algorithm, the saliency detection technique is employed to simulate the depth information. The flash-based technique is also introduced to promote the final depth-of-field rendering visual effect.
