acnode

基本解釋

ABSTRACT： The paper analyzes the regional structure evolvement of Guanghzhou development zone, including three stages: acnode, a string of beads and block.
摘要：經(jīng)過20多年的發(fā)展建設，廣州開發(fā)區(qū)經(jīng)歷了起步發(fā)展、快速擴張、綜郃優(yōu)化3個堦段，其空間形態(tài)也從“孤島”狀、“串珠”狀進而縯化到“團塊狀”的特征。
The algorithm includes two major phases: 1）removing white noise and acnode noise by threshold segmentation and grayscale neighborhood property respectively;
該算法的主要步驟分兩步：1）分別採用閾值分割和灰度鄰域屬性法消除白噪聲及孤點噪聲；
acnod
孤點

a point whose coordinates satisfy the equation of a curve although it does not lie on the curve an isolated point. The origin is an acnode of the curve y + x = x
