New low-light image enhancement method achieves high PSNR/SSIM

By PulseAugur Editorial · [1 sources] ·

A new training-free method for enhancing low-light images has been developed, combining local illumination estimation, Retinex division, and edge-preserving denoising. This approach utilizes a conditional Negative-Binominal pseudo-count method to characterize heteroscedastic noise amplified by division, resulting in an unconstrained reflectance ratio estimate. The method achieves a mean PSNR/SSIM of 17.74dB/0.739 on the LOL-v1 dataset, outperforming conventional techniques. Furthermore, it can process a 400x600 image at approximately 43 FPS on an Apple M2 Pro CPU. AI

IMPACT This method offers a potential improvement for applications requiring high-quality image processing in low-light conditions.

    Bright-Channel Retinex Enhancement with a Conditional Overdispered-Noise Analysis

    arXiv:2608.09137v1 Announce Type: new Abstract: I present a training-free low-light enhancement method that combines local bright-channel illumination estimation, Retinex division, and edge-preserving denoising. For a fixed illumination estimate, a conditional Negative -Binominal…
