OR-based Visual Cryptographic Schemes (OVCS) suffer from poor visual quality of the reconstructed image. XOR-based visual secret sharing (XVCS) can be thought of as an alternative where the relative contrast of the reconstructed image is much better. Moreover, it is possible to achieve optimum relat...
