It argues against the prevailing interpretation of dao as an unchanging metaphysical substance or reality, and maintains that the fundamental feature of heng dao is both dynamic and eternal. Heng dao is beyond language because of its dynamic character, but the Laozi nevertheless strives to express it in three aspects： 1） its flexibility and adaptability as represented in the metaphor of water; 2） its movement of reversal and return; 3） and in its existential significance as a guide for life. Heng dao can be called the non-objectified dao, which produces law, principle, rule, method, and so on. Looked at in this way, the dynamic character of heng dao can be called non-objective.展开更多

In recent years, watermarking methods which can resist this kind of distortions have attracted a lot of interests. But still many proposed methods can only deal with one certain kind of valumetric distortion such as amplitude scaling attack, and fail in other kinds of valumetric distortions like constant change attack, gamma correction or contrast stretching. In this paper, we propose a simple but effective method to tackle all the three kinds of valumetric distortions. This algorithm constructs an invariant domain first by spread transform which satisfies certain constraints. Then an amplitude scale invariant watermarking scheme is applied on the constructed domain. The validity of the approach has been confirmed by applying the watermarking scheme to Gaussian host data and real images. Experimental results confirm its intrinsic invariance against amplitude scaling, constant change attack and robustness improvement against nonlinear valumetric distortions.展开更多
