Contrast-optimal , out of , secret sharing schemes in visual cryptography,o prove optimality. They also proved that for all fixed k ≤ n, there are (k, n)-schemes with contrast (2e)./√2πk - for k = 2, 3,4 the contrast is approx. 1/105, 1/698 and 1/4380.).In this paper, we show that by solving a simple linear program, one is able to compute exactly the best contrast achievaBasilar-Artery 发表于 2025-3-29 01:02:47
