基于HSI的彩色图像二值化技术研究

当今的工业应用中存在着大量没有输出接口的数字仪表。要想自动读取仪表中的数据,只能通过识别技术。数字仪表识别的关键在于图像的二值化处理。在工业环境中实时采集的图像多为彩色图像,由于现场光线以及仪表位置等因素,应用传统的二值化技术存在处理速度慢、清晰度不高等缺点。给出一种基于HSI空间上彩色图像二值化方法。这种方法不需要对图像进行灰度处理而是直接对彩色图像进行处理,不仅能够提高处理速度,而且对较模糊的图像也能获得较好的处理效果。

Color Image Binarization Based on HSI

In today's industrial applications,there exist a variety of digital instruments without output ports,where recognition techniques have to be exploited for obtaining the measuring data automatically.The key of recognizing the digits on an instrument is image binarization.The images acquired in industrial environments are generally blurred color images affected by environmental lights,where the traditional binarization technique cannot produce good results.An approach to color image binarization based on the ...
