Abstract
A system and method are disclosed for adaptive low-light image enhancement using AI-based techniques and wavelet decomposition. The system analyzes characteristics of a raw input image, including brightness, contrast, noise levels, and detail complexity. Based on this analysis, an adaptation control subsystem determines optimal preprocessing parameters. These parameters guide an adaptive wavelet decomposition process, creating multiple frequency domain subimages. Each subimage is processed by a specialized neural network, tailored to its frequency range. The outputs of these networks are combined using an inverse wavelet transform, producing a denoised and enhanced image. This image then undergoes final processing in an image signal processing pipeline. The adaptive nature of the system allows for optimized enhancement across a wide range of low-light conditions, effectively balancing noise reduction, detail preservation, and overall image quality improvement.
