Spatial transformation and trust transaction structure of asset securitization 資產(chǎn)證券化的空間變換及其信托交易結(jié)構(gòu)
First , we compute the larger spatial transformation . then , we refine the parameters using projective transformation . it is proved that this method can produce good result and fast speed 我們采用的是基于頻域仿射模型的光流方程,即首先計(jì)算比較大的空間變換,然后再對(duì)其進(jìn)行透視變換求精,實(shí)驗(yàn)證明這樣既可以獲得較好的效果,也提高了計(jì)算速度。
