FENG Shu-qing, ZHANG Quan-fa. Study on improving success rate of edge detection for scanned image of bacteriostatic ring[J]. 2009, 28(1): 40-42+45. DOI: 10.13873/j.1000-97872009.01.012.
A method is presented to calculate automatically the best gray threshold
which is suitable for images under different scanning resolutions.By observing the morphology characteristics of the bacteriostatic ring and disturbance region
a template filter algorithm is presented to eliminate effectively the disturbance pixels around the edge of bacteriostatic ring without influence to it.Experiment achieves a very satisfactory result when doing image binarization and filtration
the success rate of edge detection of bacteriostatic ring is improves obviously.
