Better Than Reference In Low Light Image Enhancement: Conditional Re-Enhancement Networks [PDF]
arXiv, 2020 Low light images suffer from severe noise, low brightness, low contrast, etc. In previous researches, many image enhancement methods have been proposed, but few methods can deal with these problems simultaneously. In this paper, to solve these problems simultaneously, we propose a low light image enhancement method that can combined with supervised ...

Image Enhancement by Frequency Analysis
MATEC Web of Conferences, 2018 Because of lighting or the quality of CMOS/CCD, poor images are often gained, which greatly affect subjective observation. Image enhancement can improve the contrast of poor image.

Alpha-rooting color image enhancement method by two-side 2-D quaternion discrete Fourier transform followed by spatial transformation [PDF]
International Journal of Applied Control, Electrical and
Electronics Engineering (IJACEEE) Vol 6, No. 1, February 2018, 2018 In this paper a quaternion approach of enhancement method is proposed in which color in the image is considered as a single entity. This new method is referred as the alpha-rooting method of color image enhancement by the two-dimensional quaternion discrete Fourier transform (2-D QDFT) followed by a spatial transformation.

Dictionary learning based image enhancement for rarity detection [PDF]
arXiv, 2013 Image enhancement is an important image processing technique that processes images suitably for a specific application e.g. image editing. The conventional solutions of image enhancement are grouped into two categories which are spatial domain processing method and transform domain processing method such as contrast manipulation, histogram equalization,

Nonlinear Diffusion and Image Contour Enhancement
, 2003 The theory of degenerate parabolic equations of the forms \[ u_t=(\Phi(u_x))_{x} \quad {\rm and} \quad v_{t}=(\Phi(v))_{xx} \] is used to analyze the process of contour enhancement in image processing, based on the evolution model of Sethian and Malladi.

An Underwater Image Enhancement Benchmark Dataset and Beyond [PDF]
IEEE TRANSACTIONS ON IMAGE PROCESSING 2019, 2019 Underwater image enhancement has been attracting much attention due to its significance in marine engineering and aquatic robotics. Numerous underwater image enhancement algorithms have been proposed in the last few years. However, these algorithms are mainly evaluated using either synthetic datasets or few selected real-world images.
