染色体自动识别是国内外关注的课题。本文重点提出了染色体自动识别的预处理的方法。本方法是把64×64,32灰度级的染色体的编码图象,输入 FELIX C-512计算机进行分割后,作出直方图并进行滤波,使直方图平滑,利用程序找出最佳阈值,以确定染色体的几何图形。经 I 值化的染色体图象,首先进行平滑处理,将孤立点和凹凸点去掉,以提高图象质量。 Chromosome automatic identification is a topic of concern at home and abroad. This article focuses on the automatic identification of chromosome pretreatment methods. This method is the 64 × 64,32 grayscale chromosome encoded images input FELIX C-512 computer segmentation, histogram and filter to make the histogram smooth, the use of procedures to find the optimal threshold to Determine the chromosome geometry. The I value of the chromosome image, the first smoothing, the isolated point and bump removed, in order to improve image quality.
