TLDR
A (k, n)-threshold visual cryptography scheme is proposed to encode a secret image into n shadow images, where any k or more of them can visually recover the secret image, but any k - 1 or fewer of them gain no information about it.About:

Secret image sharing with steganography and authentication
Chang-Chou Lin,Wen-Hsiang Tsai +1 more
TL;DR: A novel approach to secret image sharing based on a (k, n)-threshold scheme with the additional capabilities of steganography and authentication with the capability of authenticating the fidelity of each processed camouflage image, called a stego-image is proposed.

Halftone Visual Cryptography Via Error Diffusion
TL;DR: HVC construction methods based on error diffusion are proposed, where the secret image is concurrently embedded into binary valued shares while these shares are halftoned by error diffusion-the workhorse standard of halftoning algorithms.

Two secret sharing schemes based on Boolean operations
TL;DR: A probabilistic (2,n) scheme for binary images and a deterministic (n,n), which provides a better contrast and significantly smaller recognized areas than other methods and gives an exact reconstruction.

Sharing multiple secrets in visual cryptography
TL;DR: This paper proposes a visual secret sharing scheme that encodes a set of x≥2 secrets into two circle shares such that none of any single share leaks the secrets and the x secrets can be obtained one by one by stacking the first share and the rotated second shares with x different rotation angles.

Visual Cryptography for General Access Structures
TL;DR: This paper examines graph-based access structures, i.e., access structures in which any qualified set of participants contains at least an edge of a given graph whose vertices represent the participants of the scheme, and provides a novel technique for realizing threshold visual cryptography schemes.
