Abstract

For the original random Hoff transform (RHT) in a small color image, the detection accuracy of the shortage of the circle, and if uncontrolled on the radius of the circle, not only the poor accuracy, but also a huge amount of computation.In order to improve the accuracy of finding circle, compared to the fitting, it need to provide additional parameters to control, parameter requirements more stringent, and poor overall stability. I proposed a modified RHT to find out the number of candidate circles after the vote, and then draw the circles, And comparison with the actual Contour,sorting by the actual total number of pixels overlap, then the highest score of the circle is the target circle.This method can solve the problem of low recognition accuracy. The following experiments we can see the error is improved, accuracy improvement has been very good. in improving the same time, it did not increase the amount of calculation. the algorithm has a high recognition accuracy, wide range, and strong anti-interference.
