Flexible Visual Cryptography Scheme without Distortiondoes not restrict to any specific underlying operation. Compared with other non-distortion schemes, the proposed scheme is more general and simpler, real flexible and has competitive visual quality for the recovered secret image.

An embedding rate estimator based on B-spline functions which can roughly estimate the embedding rate is proposed as well.

Simulation results demonstrate that the proposed scheme not only provides a better invisibility and security against the known counterfeiting attacks, but also allows image recovery with an acceptable visual quality up to 60% tampering.
