Abstract Digital image forgery is a major concern, requiring effective detection methods. Median filtering is widely used to smooth images but can obscure tampering. SobelMNet is a lightweight CNN designed to detect median filtering in compressed images. Utilizes Sobel filter-based preprocessing to enhance residual differences. Achieves 99.43% accuracy in detection and outperforms state-of-the-art models.
