Modeling Scene Illumination Colour for Computer Vision and Image Reproduction: A survey of computational approaches

Introduction The image recorded by a camera depends on three factors: The physical content of the scene, the illumination incident on the scene, and the characteristics

Effect of Illumination on Colour Vision Testing with Farnsworth-Munsell 100 Hue Test: Customized Colour Vision Booth versus Room Illumination

PURPOSE To evaluate a customized, portable Farnsworth-Munsell 100 (FM 100) hue viewing booth for compliance with colour vision testing standards and to compare it with room illumination in subjects with normal colour vision (trichromats), subjects with acquired colour vision defects (secondary to diabetes mellitus), and subjects with congenital colour vision defects (dichromats). METHODS Disc...

Computer Vision and Human Skin Colour

Computer vision based face and gesture recognition will allow future human computer interfaces to be more intuitive and user-friendly than traditional interfaces. A crucial processing step for the success of such systems is robust detection and tracking of faces and hands, which is frequently done by combining complementary cues, e.g., motion, shape, and colour. Skin colour is often used becaus...

Computer assisted instruction during quarantine and computer vision syndrome

Computer vision syndrome (CVS) is a set of visual, ocular, and musculoskeletal symptoms that result from long-term computer use. These symptoms include eyestrain, dry eyes, burning, pain, redness, blurred vision, etc, which increase with the duration of computer use. Currently, with the closure of schools and universities due to the continued COVID19 pandemic many universities have taken the pr...
