Title

Improving Low Illumination image based on Multi-Scale Retinex via Bilinear Interpolation

Abstract

Images taken at night in low-light situations are more likely to have poor visibility, which can affect future processing for outdoor computer vision applications. As a result, we recommend a retinex upgrade for nighttime image enhancement. Retinex is one of the most widely used techniques. It's used on photographs with non-uniform brightness in terms of colour or lightness, and it gets the job done in terms of colour consistency and dynamic range compression. Few studies have looked into retinex's performance on night-time photos, especially those taken in challenging conditions (i.e., images with over- or under-lit areas, or images with noisy speckles), where the technique can fall short. The original multi-scale retinex via Bilinear Interpolation (MSRBI) is particularly sensitive to camera noise speckles in low light, and it has a poor effect on areas with ordinary or irradiated light. In low-light circumstances, the original MSR is particularly sensitive to noise speckles produced by cameras, and it performs poorly in areas with normal or bright lighting. In addition, the original MSR used a gain-offset technique for pre-display processing, which could result in visible data loss on night-time images. This study replaces MSR's logarithm function with a customised sigmoid function to prevent data loss, and adapts MSRBI to night-time photography by combining sigmoid-MSR findings with original images.

Key Words
