Expand description

Inputs for Ghost stealth score computation.

Fields§

§num_modifications: usize

Number of STC modifications (cover != stego).

§n_used: usize

Number of cover positions used by STC (n_used).

§w: usize

STC width parameter.

§total_cost: f64

Total distortion cost from STC embedding.

§median_cost: f32

Median cost across all positions (before STC).

§is_si: bool

Whether SI-UNIWARD (Deep Cover) was used.

§shadow_modifications: usize

Number of shadow LSB modifications (0 if no shadows).

§total_coefficients: usize

Total number of Y-channel coefficients in the image.
