基于视觉注意力模型的背景斑点提取方法

A method to extract the pattern from background based on visual attention model

针对传统人工选取背景斑点的不足,提出了一种基于视觉注意力模型的背景斑点提取方法。首先根据Itti显著图模型确定背景图中的显著区域;然后找出若干注意视点,并将这些视点作为种子点在原图上进行区域生长;最后在区域生长的基础上依据相关准则提取出斑点。实验结果表明,该方法可以准确地找到背景图中的明显斑点,使进一步的背景斑点分析成为可能。

Because of the shortage of the extracting the background pattern by men in tradition,a method to extract the pattern from background based on visual attention model is presented.First the saliency area in the background image is ascertained according to the Itti saliency map model;then some attention vision focus are found and they are used as the seed to do region growing in the image;at last the pattern is extracted from background according to the rule.The experimental results show that this method can exactly find the saliency pattern in background image,and it also makes the farther pattern analysis be possible.
