Research of an Improved Snail Image Recognition Method Based on Grayscale Template Matching

As the lack in the accuracy and speed of the template matching algorithm for the snail image in the complex environment, the snail sourceimage and the template image have the appropriate scaling in order to improve their sizes in the traditional algorithm. The new algorithm avoids the very big and accurate characteristics about the snail images through shrinking the source images down. The grayscale template matching method is put forward based on the traditional template selection set to prevent that the error caused by human factors on the selected template,the redundancy between the templatesis removed in a large extent, further the accuracy of the matching improved, and the matching time is reduced greatly in the case of matching accuracy guarantee.
