There appeared, within three feet of him, a form clad in pure white - a youthful, graceful form : full, yet fine in contour ; and when, after bending to caress carlo, it lifted up its head, and threw back a long veil, there bloomed under his glance a face of perfect beauty
離他三尺的地方，有一個穿著純白衣服的形體一一年青而優美的形體，豐滿而線條很美。這人彎下腰下去撫摸卡羅時，抬起了頭，把長長的面紗扔到后頭，於是一張花也似的美妙絕倫的面孔，映入了他的眼簾。 -
Wiener method is based on statistics estimated from a local neighborhood of each pixel. ( 2 ) acquisition of head and brain volumetric data and development real head and brain reconstruction and visualization algorithms : by using threshold technique and morphological operations such as dilate and erosion, head segmented data were obtained. to obtain the brain segmented data, construct an initial template, design and developed a naval algorithm to make the initial template dynamic change with image slice to get the brain data ; designed a framework for searching, sampling and storing contour data
