Abstract:

In order to solve the image matching problems in the field of missile guidance,target search and other fields,a fast image matching method-the matching function method based on the sub-image features is proposed to accelerate the speed of matching.The matching image and the search image are divided into a number of sub-images of the same size and their scale invariant features are calculated.These features form a sequence.The failure function produces the matching results by calculating the characteristic sequences of the two images.It takes advantage of the characteristic sequences of the image itself to improve the search speed of image matching.Due to the association of the image characteristic sequences,the algorithm does not restart its application from the original characteristics sequence,but according to the lapse function,producing a new position to matching.
