中文摘要：
在HSI颜色模型基础上提出了一种融合颜色和空间信息的彩色图像二值化算法。该算法对H,S,I通道依次进行动态阈值法、高低阈值法和直方图固定阈值法分割,并应用阈值结果到全局信息来获取二值化结果;针对阈值处理带来的纹理和光影的过分割,使用彩色形态学开运算进行区域合并。测试证明,此算法提取率高达98%,运行速度满足实时性要求。
英文摘要：
A Binary-Conversion method of color image using combined information of color and space features based on the HSI color model is proposed.The algorithm handles the H,S and I components by dynamic threshold method,high and low threshold method and fixed threshold histogram segmentation method,and applied the threshold result to the global information access to get the binarization result.The over-segmentation of texture and shadow which was caused by threshold division is settled by the morphological opening operation to merge region.The experimental results proves that the extraction rate of color image can achieve 98 % and the running time meets the real-time requirements.
