Photographic Depth of Field Blur Rendering
The purpose of our study is to introduce a new method for depth of field blur simulation used for compositing real and synthetic images in a realistic way. Existing methods do not simulate accurately the depth of field blur produced by photographic equipment. The problem is twofold: photometric and geometric. Existing methods based on convolution do not produce a realistic photometric rendering...
متن کاملParameter Estimation for Photographic Tone Reproduction
Tone reproduction algorithms attempt to compress a large range of pixel values into a smaller range that is suitable for display on devices with limited dynamic range. A recently proposed tone reproduction operator achieved this goal by emulating photographic practice. Like in photography, the manual tuning of a small set of intuitive parameters was required. In this paper we extend this photog...
متن کاملConstructing And Rendering Vectorised Photographic Images
We address the problem of representing captured images in the continuous mathematical space more usually associated with certain forms of drawn (’vector’) images. Such an image is resolution-independent so can be used as a master for varying resolution-specific formats. We briefly describe the main features of a vectorising codec for photographic images, whose significance is that drawing progr...
متن کاملReal-Time Photographic Local Tone Reproduction Using Summed-Area Tables
High dynamic range (HDR) rendering is becoming an increasingly popular technique in computer graphics. Its challenge consists in mapping the resulting images’ large range of intensities to the much narrower ones of the display devices in a way that preserves contrastive details. Local tone mapping operators effectively perform the required compression by adapting the luminance level of each pix...
متن کاملTone Reproduction and Physically Based Spectral Rendering
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. This STAR addresses two related key problem areas in this effort which are located at opposite ends of the rendering pipeline, namely the data structures used to describe light during the actual rendering process, and the issue of displaying such radiant int...
