LOW-COST NIGHT VISION CAMERA BASED ON A MODIFIED CONSUMER WEBCAM AND LIGHTWEIGHT REAL-TIME ENHANCEMENT

Journal of Problems in Computer Science and Information Technologies
Low-light perception is a core requirement for robotics, inspection, and wearable situational awareness, yet reliable night- vision solutions often require expensive sensors or computation- ally heavy processing.

Color Vision is a Spatial Process: The Retinex Theory

, 2017
Born through the work of Edwin H. Land and John J. McCann more than 40 years ago, Retinex theory proposes a computational model to explain and estimate the human color sensation, i.e. the color perception that human vision system produces when oberving a

Properties of a center/surround retinex. Part 1: Signal processing design [PDF]

, 1995
The last version of Edwin Land's retinex model for human vision's lightness and color constancy has been implemented. Previous research has established the mathematical foundations of Land's retinex but has not examined specific design issues and their ...

Diff-Retinex: Rethinking Low-light Image Enhancement with A Generative Diffusion Model

, 2023
In this paper, we rethink the low-light image enhancement task and propose a physically explainable and generative diffusion model for low-light image enhancement, termed as Diff-Retinex.

Color and Luminance Separated Enhancement for Low-Light Images with Brightness Guidance

Sensors
Existing retinex-based low-light image enhancement strategies focus heavily on crafting complex networks for Retinex decomposition but often result in imprecise estimations.

DSP Implementation of the Retinex Image Enhancement Algorithm

, 2004
The Retinex is a general-purpose image enhancement algorithm that is used to produce good visual representations of scenes. It performs a non-linear spatial/spectral transform that synthesizes strong local contrast enhancement and color constancy. A real-
