Chinese Abstract

對多邊形Voronoi圖和中軸兩個概念進行了重新定義以適應更廣泛的工程應用。分析對比了含直線段、圓弧和自由曲線的區域輪廓邊界Voronoi圖和中軸的各自的特徵,給出了二者在凸多邊形、簡單多邊形等不同情況下的相互關係及證明。

English Abstract

Aiming at the characteristics of the marrow cell image, the paper adopts continuous wavelet transform to process image so that main edges can be detected from different angle in the meanwhile original image noise being eliminated. Adopt two neural networks; Using Principal Component Analysis based neural network (GHA) to acquire three principal components and using Simulated Annealing (SA) and BP network to class and recognize the marrow cells.
