Thyroid tissue localization pipeline. Tissue localization is applied at the 4th level of the whole slide image to eliminate background regions that are irrelevant to slide diagnosis, thereby speeding up the automatic diagnosis process. Color space conversion, image smoothing, inverse binarization, and binary image refinement are successively applied to generate the thyroid tissue mask.
