Blind Inverse Gamma Correction With Maximized Differential Entropy [PDF]
Signal Processing, 2022 Unwanted nonlinear gamma distortion frequently occurs in a great diversity of images during the procedures of image acquisition, processing, and/or display. And the gamma distortion often varies with capture setup change and luminance variation. Blind inverse gamma correction, which automatically determines a proper restoration gamma value from a given

Blind Inverse Gamma Correction
IEEE Transactions on Image Processing, 2001The luminance nonlinearity introduced by many imaging devices can often be described by a simple point-wise operation (gamma correction). This paper presents a technique for blindly estimating the amount of gamma correction in the absence of any calibration information or knowledge of the imaging device.

Visual gamma correction for LCD displays
Displays, 2011Abstract An improved method for visual gamma correction is developed for LCD displays to increase the accuracy of digital colour reproduction. Rather than utilising a photometric measurement device, we use observers’ visual luminance judgements for gamma correction.

Retrieval of gamma corrected images
Pattern Recognition Letters, 2001Summary: This paper presents a histogram based image retrieval system for environments where the images may be subject to gamma correction. The images are transformed into representations that are invariant under gamma correction. The differential invariant employed is a local feature implemented with derivatives of the Gaussian. The image retrieval is

Lens Correction and Gamma Correction
2014Recently, the necessity of camera in vehicle industry is increasing now as increasing the smart car needs. Almost smart car concepts are implemented by using the camera system based on image processing technology. Actually, the rear view camera for parking assistance system, the forward view camera for lane departure warning and forward collision ...
