A New iCAM-based HDR Image Display Algorithm

摘要：

A new High-Dynamic-Range (HDR) image rendering algorithm based on iCAM (image Color Appearance Model) was developed in this paper. The predicting models for “Hunt effect and “Stevens effect were integrated into HDR image rendering algorithm based on iCAM. Then, the optimum range of parameter “c in the predicting model for “Hunt effect and parameter “m in the predicting model for “Stevens effect were defined respectively by the corresponding experiments aimed at the two purposes of evaluation (rendering preference evaluation and rendering accuracy evaluation). The final complete predicting models for “Hunt effect and “Stevens effect were integrated into the algorithm flow. The result of rendering preference experiment shows the algorithm improved has significant better performance than four algorithms in PhotoShopCS4 and the iCAM algorithm unimproved. The result of rendering accuracy experiment shows the algorithm improved has significant better performance than the iCAM algorithm unimproved, and is equivalent to PhotoShop algorithms.
