Local Contrast Enhancement for Improving Screen Images Exposed to Intensive External Light

  title={Local Contrast Enhancement for Improving Screen Images Exposed to Intensive External Light},
  author={Dmitry Lebedev and Galina I. Rozhkova and V. A. Bastakov and C.-Y. Kim and S.-D. Lee},
When a mobile device (notebook, smartphone, etc.) is used, the images on the monitor screen may be significantly distorted by a strong external light (for instance, sunlight) illuminating the screen surface. This additional illumination reduces all the local contrast values in the displayed images and leads to fading and deterioration of the subjective visual images thus impeding image recognition and analysis. A technique of processing the input digital video signal in such a way that, in… Expand

Joint Visual Sharpness-Contrast-Tone Mapping Model
A joint sharpness-contrast mapping model cooperating with the adaptive scale-gain MSR (Multi-Scale Retinex) that enhances the visual contrast and sharpness as well as tonal color reproduction under the ill-suited illumination. Expand
Learning Preferential Perceptual Exposure for HDR Displays
This paper establishes user preferred exposure values for a variety of maximum display brightnesses, content and ambient lighting levels, then develops two models to predict preferred exposure, based on linear regression using straightforward image statistics and convolutional neural networks.

Visual calibration and correction for ambient illumination
A method whereby the display device itself can be used to determine the effect of ambient light on perceived contrast, thus enabling the viewers themselves to perform visual calibration, so that the contrast of an image view in bright conditions can be corrected to appear the same as an image viewed in a darkened room.

Dynamic-range compression and contrast enhancement in infrared imaging systems
A new method is presented that combines dynamic-range compression and contrast enhancement techniques to improve the visualization of infrared images and demonstrates the effectiveness of the proposed technique in terms of perceptibility of details, edge sharpness, robustness against the horizon effect, and presence of very warm objects. Expand
Contrast enhancement based on a novel homogeneity measurement
A novel homogeneity measurement is proposed and utilize it to define and enhance the contrast and the results prove that the proposed method has better performance than the existing methods, no over-enhancement/under-enhancesment and more robust. Expand
Image Contrast Enhancement by Constrained Local Histogram Equalization
A constrained local histogram equalization method is proposed to balance the conflicting requirements: enhancement of the image details and the maintenance of the overall image appearance. Expand
Adaptive contrast enhancement and de-enhancement
Two different interpolative schemes for adaptive contrast enhancement have been presented for speeding up the contrast enhancement algorithm proposed by Beghdadi and Negrate and a contrast transformation function is proposed which can be used for adaptive enhancement as well as de-enhancement of images. Expand
Image Contrast Enhancement Based on a Histogram Transformation of Local Standard Deviation
It is shown that conventional ACE's use linear functions to compute the new CG's, but the proposed nonlinear function produces an adequate CG resulting in little noise overenhancement and fewer ringing artifacts. Expand
A multiscale morphological approach to local contrast enhancement
The conventional theoretical concept of local Contrast enhancement has been extended in the regime of mathematical morphology and the intensity values of the scale-specific features of the image extracted using multiscale tophat transformation are modified for achieving local contrast enhancement.

An advanced contrast enhancement using partially overlapped sub-block histogram equalization
A low-pass filter-type mask is used to get a nonoverlapped sub-block histogram-equalization function to produce the high contrast associated with local histograms equalization but with the simplicity of global histogram equalization. Expand
Contrast enhancement technique based on local detection of edges
The technique, derived from Gordon's algorithm, accounts for visual perception criteria, namely for contour detection, and the efficiency of the algorithm is compared to Gordon's and to the classical ones. Expand
