Graph-Based Joint Dequantization and Contrast Enhancement of Poorly Lit JPEG Images
JPEG images captured in poor lighting conditions suffer from both low luminance contrast and coarse quantization artifacts due to lossy compression. Performing dequantization and contrast enhancement in separate back-to-back steps would amplify the residual compression artifacts, resulting in low vi...
