用EL99算法合成纹理，速度比较慢，效果还不错，适用于大多数纹理的合成-EL99 algorithm using synthetic texture, fairly slow, and the results were pretty good, applicable to the majority of the texture synthesis

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
