tUTOTHRESHOLDING OF NOISY IMAGES |
| 摘要 |
The present invention provides to image processing methods that include a method of selecting an optimal threshold value (t<o#191) for an image comprising the steps of: obtaining an image; selecting a test segment of the said image; determining the mean feature size (S) of features appearing in the test segment at each of a plurality of threshold values (t), so as to produce mean feature size data (S(t)); selecting a relevant subset of the mean feature size data (S(t)); and determining an optimal threshold value (t?o#191) as a function of said subset of the mean feature size data. The present invention additionally provides methods of thresholding an image to produce a binary image by application of the optimal threshold value (t?o#191) determined according to the methods of the present invention. |
