针对色调在颜色量化时容易出现偏差,提出了一种基于直方图特性的颜色量化算法,在颜色量化时对色调进行修正,并采用脉冲耦合神经网络对颜色量化结果进行分割验证.-For color in the color quantization error prone, a feature based on the color histogram quantization algorithm, when the color quantization for color correction, and using pulse coupled neural network segmentation of color quantization results verified.
