Underwater Image Enhancement via Weighted Wavelet Visual Perception Fusion
IEEE transactions on circuits and systems for video technology (Print)Underwater images typically suffer from various quality degradation issues due to the scattering and absorption of light, but these degraded-quality underwater images are unbeneficial for analysis and applications.

Publisher Summary With image enhancement, the visibility of selected features in an image can be improved, but the inherent information content cannot be increased. The design of a good image enhancement algorithm should consider the specific features of interest in the microscopic image and the imaging process itself. The image enhancement algorithms

Narrow band imaging (NBI) can emphasize images of the surface microvasculature of lesions, because the central wavelengths of the NBI filter are 415 and 540 nm and these wavelengths are well absorbed by hemoglobin. Flexible spectral imaging color enhancement (FICE) increases the contrast in depictions of mucosal lesions.

Underwater Image Enhancement With Reinforcement Learning
IEEE Journal of Oceanic EngineeringIn this article, we develop an underwater image enhancement framework based on reinforcement learning. To do this, we model the underwater image enhancement as a Markov decision process (MDP), in which states are represented by image feature maps ...

Underwater Image Enhancement Using a Multiscale Dense Generative Adversarial Network
IEEE Journal of Oceanic Engineering, 2020Underwater image enhancement has received much attention in underwater vision research. However, raw underwater images easily suffer from color distortion, underexposure, and fuzz caused by the underwater scene.

Multiscale Low-Light Image Enhancement Network With Illumination Constraint
IEEE transactions on circuits and systems for video technology (Print), 2022Images captured under low-light environments typically have poor visibility, affecting many advanced computer vision tasks. In recent years, there have been some low-light image enhancement models based on deep learning, but they have not been able to ...

Recognition of Enhanced Images
11th International Multimedia Modelling Conference, 2005Image enhancement such as adjusting brightness and contrast is central to improving human visualization of images content. Images in desired enhanced quality facilitate analysis, interpretation, classification, information exchange, indexing and retrieval.

Image enhancement in ultrasound imaging
2016 24th Signal Processing and Communication Application Conference (SIU), 2016In this paper, two different methods are suggested in order to provide image enhancement in ultrasonic B-mode imaging. By obtaining RF data from two different phantom used to form B-mode image, their spectral characteristics were observed. Then by forming RF envelope from obtained data, conversion of envelope to color image is provided.
