1 用WL00算法速度比EL99快，这里实现的是单分辨率的算法,WL00算法好象不适合结构性强的纹理的合成

2.用WL00算法合成纹理，使用多分辨率金字塔改善合成效果,但是没有用TVSQ加速算法-WL00 algorithm with a speed faster than the EL99, here is the realization of the single-resolution algorithm, WL00 algorithm does not seem to fit the strong structural texture synthesis 2. WL00 algorithm using synthetic texture, the use of multi-resolution pyramid improve synthesis results, but did not accelerate the algorithm used TVSQ
