Binary projection for image local descriptor
Yicheng MAI · Journal of Computer Applications · 2013
In order to reduce the computational burden and maintain the recognition rate of the image local descriptor,a binary projection method for image local descriptor was proposed.The image patch was projected and transformed into a binary string for boosting the performance as well as speeding up the matching speed.The projection matrix was optimized by machine learning method to maintain its recognition rate and robustness.The experimental result indicates that only a 32-bit binary string is needed to perform as well as the state-of-art descriptors and it shows significantly faster matching speed.
