一种复杂图像背景中残留液晶识别方法
Identification method of rudimental liquid crystal in complex background image
摘要
Abstract
LCD screen requires strict surface cleanliness.The inspection method based on digital image processing focusing on the residual liquid crystal can give quantitative and objective assessment on the components surface cleanliness.According to the difficulty to identify the rudimental liquid accurately in a complex background image,this paper proposes an effective image processing flow and algorithm, including the operation of segmentation,edge connection,image filling,redundant boundary and noise removing,etc.An edge connecting operator is designed to connect the discontinuous boundary in the image after the segmentation.A classifier is designed and implemented based on binary classifi-cation method for automatic identification of geometry types of contaminants.Experiments show that the residual liquid crystal in the simple background image can accurately inspected, and the interference of the noise is excluded.The identification and analysis method for the complex back-ground image can accurately process particular types of images that their backgrounds have significant differences.关键词
