What is Steganographic Fisher Information Estimation about?

This document presents a method for estimating steganographic capacity in digital images using information theory. It defines Steganographic Fisher Information (SFI), which characterizes the asymptotic behavior of KL divergence between cover and stego distributions as payload size approaches zero. The document proposes estimating SFI by considering small groups of pixels rather than whole images. It then describes experiments estimating SFI for different types of pixel groups to compare embedding methods an
