- Abstract
The width parameter detection method based on colloidal gold strip microscopic image has lots of merits such as easy operation, high testing speed, and high resolution. However, the coHoidal gold strip microscopic image is inevitable slanted by many factors. The slanted image is difficult to be segmented and measured. So it is necessary to rectify the slanted image before it is segmented and measured. According to the advantages of Hough transform method and the least-square method in the line detection, a method combining Hough transform and the least-square is proposed to detect the edge lines of the colloidal gold strip microscopic image and find the angle parameters of the edge lines. Image rotation algorithm is used to rotate the slanted image and get the correction image. Experiments show that the method has high detection precision with less computer memory and shorter calculation time, and the measure result is accurate.
