High Dynamic Range Image Encodings
نویسنده
چکیده
We stand on the threshold of a new era in digital imaging, when image files will encode the color gamut and dynamic range of the original scene, rather than the limited subspace that can be conveniently displayed with 20 year-old monitor technology. In order to accomplish this goal, we need to agree upon a standard encoding for high dynamic range (HDR) image information. Paralleling conventional image formats, there are many HDR standards to choose from.

High Dynamic Range Image Encodings
An important consideration for any digital 03 image is how to store it. This is especially true for high dynamic range (HDR) images, which record a much wider gamut than standard 24-bit RGB, and therefore require an efficient encoding to avoid taking up an excess of disk space and network bandwidth. Fortunately, several HDR file encodings and formats have already been developed by the graphics ...
متن کاملEvaluation of color encodings for high dynamic range pixels
Traditional Low Dynamic Range (LDR) color spaces encode a small fraction of the visible color gamut, which does not encompass the range of colors produced on upcoming High Dynamic Range (HDR) displays. Future imaging systems will require encoding much wider color gamut and luminance range. Such wide color gamut can be represented using floating point HDR pixel values but those are inefficient t...
متن کاملOvercoming Gamut and Dynamic Range Limitations in Digital Images
The human eye can accommodate luminance in a single view over a range of about 10,000:1 and is capable of distinguishing about 10,000 colors at a given brightness. By comparison, typical CRT displays have a luminance range less than 100:1 and cover about half of the visible color gamut. Despite this difference, most digital image formats are geared to the capabilities of conventional displays, ...

متن کاملImage Retrieval Using Dynamic Weighting of Compressed High Level Features Framework with LER Matrix
In this article, a fabulous method for database retrieval is proposed. The multi-resolution modified wavelet transform for each of image is computed and the standard deviation and average are utilized as the textural features. Then, the proposed modified bit-based color histogram and edge detectors were utilized to define the high level features. A feedback-based dynamic weighting of shap...
