基于图像特征的色调映射方法评价体系
Evaluation System of Tone Mapping Method Based on Image Features
摘要
Abstract
In order to solve the problem of accurate display for High Dynamic Range(HDR) images on the traditional display device,this paper converts the uncertain visual attention mechanism to the number of certain features and proposes an evaluation system based on image feature to identify whether the resulted image of the tone mapping method keeps the features or not.Drastic contrast adjustment is made for the images,and the brightness of the scene is transformed into a range that can be displayed,while maintaining details and color which are very important for the display of the original scene.Seven global tone mapping methods are compared and analyzed,which are LogarithmicTMO,ExponentialTMO,TumblinRushmeierTMO,SchlickTMO,FerwerdaTMO,WardHistAdjTMO and DragoTMO.The overall effect of WardHistAdjTMO tone mapping is optimal.关键词
