基于视觉效应的自适应图像隐写算法
Adaptive Steganography Algorithm Based on Vision Effect
摘要
Abstract
In the spatial domain, the characteristic parameters "chroma" and "colour difference" based on the theory of light mix are proposed to describe insensitive feeling through calculating the feature vector in Euclid space. The optimum location can be found by filtering the parameters. Using figure characters, we propose a novel algorithm to put information into image adaptively, so that it can maintain figure characters. Steg-anography information can be obtained without original image by recording information location. At the same time, the steganography protocol used in this algorithm avoids transmitting misinformation effectively. The theoretical analysis, confirmed by experimental results, shows that the proposed algorithm has a good vision effect. Neitherχ2 analysis nor RS analysis can confirm whether the image has been disposed or not.关键词
