一种彩色印刷图像网点检测与识别算法的研究

An Algorithm of Detecting and Recognizing Dots in Color Printing Images

针对当前印刷图像色彩检测和控制的方式及设备存在的不足 ,提出了一种新的基于数字图像处理和模式识别技术的网点检测与分色方法 ,并依此设计出了基于色度检测法的网点检测和识别系统———DIA系统 ;最后通过实验验证了该方法的有效性。

For overcoming the drawbacks of existing methods and devices for detecting and controlling colors of the printing images, a new method based on digital imaging and pattern recognition was proposed to detect dots and separate colors. Then DIA system, a dot detecting and recognizing system based on the colorimetric measurement, was designed according to this principle; finally some experiments were carried out to prove its validity.
