(a) The result of the esophagus test is normal. It is not displayed under the diagnosis of SSD. (b) represents the detection result of the area with low-grade dysplasia, under the diagnosis of SSD, the blue bounding box surrounds the lesion area; (c) shows the area with high-grade dysplasia. The test result shows that the gray bounding box surrounds the lesion area under the diagnosis of SSD; (d) shows the detection result of the invasive cancer area, and the orange bounding box surrounds the lesion area under the diagnosis of SSD.
