摘　　要：基于RGB颜色空间,对目前使用较为广泛和最近使用的几种RGB颜色色差算法进行分析对比,评价其优缺点,吸收它们的优点,屏蔽它们的缺点,提出了一种全新的基于特征向量的色差公式。给出了基于RGB颜色空间的特征提取方法和特征向量的色差计算方法。通过图像的分割实验对比,验证了本算法的有效性和平滑性。本算法得到的色彩容差符合人眼的视觉判断。由于本算法具有较小的时间复杂度和空间复杂度,可应用于实际生产与生活。Based on study of RGB color space and the compares and analysis of several color difference formulas in currently and recently usage,evaluating its merit and shortcoming,absorbing their advantages,shielding their weakness,a brand new formula based on feature vector to compute the color difference is put forward.Based on RGB color space,the method of feature extraction and the method of compute the feature vector are given.Through the image segmentation contrast experiment,verified the effectiveness and smoothness of our method.This algorithm＇s calculation results is suitable according with human visual judgment.This algorithm has smaller time complexity and space complexity,so can be applied in practical production and life.
