Reasearch on the condom image detection algorithm for automatic sorting

To realize the automatic sorting before electrical testing of condoms, the position of condom ring needs to be discriminated with image processing method. Procedures for ellipse detection are written based on OpenCV, Gauss filter is applied to smooth the collected images, and then Canny operator is used for edge detection, combined with the modified Hough transform method to determine the ellipse center to achieve the effective detection of the condom ring.
