Image Tone Mapping for an HDR Image by Adoptive Global tone-mapping algorithm
It is the age of fast and good quality Digital images, those are subject to blurring due to many hardware limitations, such as atmospheric disturbance, apparatus noise and poor focus quality. Visual saliency aims to predict the attentional steady intent look of observers viewing a scene, and therefore tone mapping of high dynamic range (HDR) images concept is highly useful for it. The work has ...
متن کاملWatermarking for HDR Image Robust to Tone Mapping
High Dynamic Range (HDR) images have been widely applied in daily applications. However, HDR image is special format, which need to pre-process known as tone mapping operators for display. Since the visual quality of HDR images are very sensitive to luminance value variations, conventional watermarking methods for low dynamic range (LDR) images are not suitable and may even cause catastrophic v...
متن کاملHuman-visual-system-inspired tone mapping algorithm for HDR images
In this paper we present a tone mapping operator (TMO) for High Dynamic Range images, inspired by human visual system adaptive mechanisms. The proposed TMO is able to perform color constancy without a priori information about the scene. This is a consequence of its HVS inspiration. In our humble opinion, color constancy is very useful in TMO since we assume that it is preferable to look at an i...
متن کاملTone Mapping Techniques and Color Image Difference in Global Illumination
Tone mapping is the final step of every rendering process. Due to display devices’ nonlinearities, reduced color gamuts and moderate dynamic ranges it is necessary to apply some mapping technique on the computed radiances. We described mapping methods that are considered to be state of the art today, and some newly developed techniques. The main contributions of this thesis in tone mapping tech...
متن کاملBeyond Tone Mapping: Enhanced Depiction of Tone Mapped HDR Images
High Dynamic Range (HDR) images capture the full range of luminance present in real world scenes, and unlike Low Dynamic Range (LDR) images, can simultaneously contain detailed information in the deepest of shadows and the brightest of light sources. For display or aesthetic purposes, it is often necessary to perform tone mapping, which creates LDR depictions of HDR images at the cost of contra...
