چکیده

Because of the progress of the digital camera technique recently, we can directly obtain the HDRI (High Dynamic Range Image) from camera. Nevertheless, limited by display, we still transfer the HDRI to the display which can show LDRI (Low Dynamic Range Image). This technique is known as tone-mapping. The goal of tone-mapping is to compress the luminance dynamic range into low dynamic range while decreasing distortion and preserving detail. We use logarithm first to compress high dynamic range based on background luminance. The retinex local contrast enhancement is thus being performed to enhancement the image in dark regions. Using our method can preserve most of detail without contrast distortion especially dark areas.

Image Processing for Human Understanding in Low-visibility

Low-visibility conditions for navigation of vehicles are a frequent occurrence. Driving at night, in blizzards, in sand storms, or in fog form an obvious set of challenging conditions. Remote operation of unmanned vehicles through a camera image provides a similar difficulty. Gathering intelligence from satellite imagery can similarly benefit from improved visibility. Advanced image processing ...

Tone Mapping Algorithm for Luminance Separated HDR Rendering Based on Visual Brightness Functions

Tone mapping algorithms are used in image processing that reduces the range of high dynamic range (HDR) image to be displayed on low dynamic range (LDR) devices. The retinex method is one of the tone mapping algorithms to provide dynamic range compression, color constancy, and color rendition. It has been developed from single scale methods to multi-scale methods. Retinex algorithms still have ...

A Novel Tone Mapping Method for High Dynamic Range Image by Incorporating Edge-Preserving Filter Into Method Based on Retinex

A tone mapping method for high dynamic range image is proposed to prevent the halo artifacts, which is easy to be produced in traditional method based on the Retinex theory in handling high dynamic range(HDR) image. Our method is based on the Retinex theory. The novelties of our method is first to employ a local edge-preserving filter for the estimation of the illumination, which can smooth out...

The Influence of Luminance on Local Tone Mapping

We study the influence of the choice of color space for local tone mapping methods. Many local tone mapping methods do not perform well when applied independently to the three color channels of an RGB image. A common solution is to only treat the luminance channel. However, the question of which color space provides the most suitable luminance definition has not been addressed. The correlation ...
