| Abstract: | Based on a measuring system using digital image processing and recognition,several algorithms of contour extracting are analyzed and compared.With the combination of optimal thresholding and contour tracking,the air bubble image taken by CCD camera is examined.As a result,the balancing result for calibration is improved and the noise of the image is reduced. |
