Article Synopsis
- The study investigates how advancements in image manipulation tools have led to increased concerns over digital image forgery, specifically focusing on image splicing, which merges parts of different images.
- It highlights the limitations of existing detection algorithms that often struggle with high-dimensional feature vectors and aims to enhance detection accuracy using low-dimensional vectors.
- The research introduces an approximated Machado fractional entropy (AMFE) combined with discrete wavelet transform (DWT) to capture image splicing artifacts effectively, demonstrating improved accuracy in detection through testing on the CASIA v2 dataset.
