Consistent Tone Reproduction
In order to display images of high dynamic range (HDR), tone reproduction operators are usually applied that reduce the dynamic range to that of the display device. Generally, parameters need to be adjusted for each new image to achieve good results. Consistent tone reproduction across different images is therefore difficult to achieve, which is especially true for global operators and to some ...
متن کاملTone Reproduction for Interactive Walkthroughs
When a rendering algorithm has created a pixel array of radiance values the task of producing an image is not yet completed. In fact, to visualize the result the radiance values still have to be mapped to luminances, which can be reproduced by the used display. This step is performed with the help of tone reproduction operators. These tools have mainly been applied to still images, but of cours...
متن کاملColor Correction for Tone Reproduction
High dynamic range images require tone reproduction to match the range of values to the capabilities of the display. For computational reasons as well as absence of fully calibrated imagery, rudimentary color reproduction is often added as a postprocessing step rather than integrated into the tone reproduction algorithm. However, in the general case this currently requires manual parameter tuni...
متن کاملSmart Tone Reproduction of Digital Images
In this paper, we propose an effective scheme for enhancing the visual details of digital images with the minimal amount of user adjustment. Digital archives are becoming increasingly popular due to the development of convenient and powerful digitizing techniques. However, a substantial number of digital images suffer from loss of detail because they were captured with old-fashioned equipment. ...
متن کاملA review of tone reproduction techniques
The ultimate aim of realistic graphics is the creation of images that provoke the same responses that a viewer would have to a real scene. While research into ways of rendering images provides us with better and faster methods, we do not necessarily see their full effect due to limitations of the display hardware. The low dynamic range of a standard computer monitor requires some form of mappin...
