Study on Artificial Mark Recognition in Augmented Reality

Artificial mark recognition,including mark area recognition and mark pattern recognition,is a significant process of augmented reality.A method to recognize mark area by connectivity area abstraction of the binary image which includes marks,is presented.According to different mark pattern recognition,a method based on the number of connectivity areas of the pattern and a method based on template match are presented.The result proves the methods presented can recognize the marks accurately,which gets prepared for the real time synthesis of the virtual and the real.
