Target pre-detection based on visual attention
Bin Zhu · Journal of Chongqing University. English Edition · 2009
An improved integration model combining the bottom-up and top-down cues for visual attention is proposed.It uses an integrated outline as the symbol for object recognition and overcomes the shortcomings of the top-down visual attention method that needs excessive a priori knowledge.Furthermore,adopting the object outline as the main character for recognition and pre-detection also overcomes the drawbacks existing in the bottom-up visual attention model that only uses three saliency maps from the original picture,resulting in an overextended recognition region.Experimental results show that compared to the original algorithm,the proposed algorithm is more effective for target pre-detection.
