The visual quality of photographs taken under imperfect lightness conditions can be degenerated by multiple factors, e.g., low lightness, imaging noise, color distortion, and so on. Current low-light image enhancement models focus on the improvement only, or simply deal with all degeneration factors as a whole, therefore leading to sub-optimal results. In this article, we propose decouple model...
Due to inadequate energy captured by the hyperspectral camera sensor in poor illumination conditions, low-light images (HSIs) usually suffer from low visibility, spectral distortion, and various noises. A range of HSI restoration methods have been developed, yet their effectiveness enhancing HSIs is constrained. This work focuses on enhancement task, which aims reveal spatial-spectral informati...
In this paper, we introduce a tone mapping algorithm for processing high-brightness video images. This method can maximally recover the information of areas and preserve detailed information. Along with benchmark data, real-life practical application data were taken to test proposed method. The experimental objects license plates. We reconstructed image in RGB channel, gamma correction was carr...
Using global contrast enhancement, low contrast image can be improved in its quality globally. The enhanced output image, with such type of enhancement, may not have the noise and ringing artifacts. However, it may have over-exposure on some parts of the image and under-exposure on some other parts of the image when too high contrast gain occurs. Besides these, the enhanced output image may lac...
