Title Research and implementation of image matching search algorithm
Abstract
As image matching image registration process technology, image processing is fundamental issue, but also a key step in many image analysis and processing tasks, it has very important significance and practical value. Using image matching technology to improve the efficiency in the plant leaf identification recognition. Using digital image processing technology and plant leaves are processed to extract image features. The relative value of leaf extract geometric features combine six invariant moments leaf used for feature matching. System will eventually use Android as a client, PC machine as a server to achieve plant leaf recognition system. Experimental results show that this kind of matching method has some effect, of course, there are some flaws to be further improved.
