Retinal photography is a standard method for recording retinal diseases for subsequent analysis and diagnosis. However, the currently used white light or red-free retinal imaging does not necessarily provide the best possible visibility of different types of retinal lesions, important when developing diagnostic tools for handheld devices, such as smartphones. Using specifically designed illumination,...
We report much improved color gamut liquid crystal displays (LCDs) with specially engineered low-reabsorption, narrow emission spectrum and high quantum yield colloidal quantum-dot light converting device (QLCD) and its applications to TV displays. By theoretical and experimental optimizations, color gamut as wide as 120% NTSC standard is demonstrated. QCLD has also been tested for stability under...
In this study, a novel single-image based dehazing framework is proposed to remove haze artifacts from images through local atmospheric light estimation. We use a novel strategy based on a physical model where the extreme intensity of each RGB pixel is used to define an initial atmospheric veil (local atmospheric light veil). Across bilateral filter is applied to each veil to achieve both local smoothness...
