Table 2.

AFB single-frame dataset, subdivided into train, validate, and test datasets. The complete dataset consists of 685 $720\times 720$ video frames. The column “Cases” indicates the number of patient airway exams used for a given data subset. The “Total frames” and “Split ratio” columns indicate the number of frames and the percentage of frames, respectively, that were allocated to a particular subset. For an entry of the form “A/B” in these two columns, “A” corresponds to lesion frames and “B” corresponds to normal frames. Lastly, the column “Size range” denotes the percentage of pixels within of a frame’s circular scan area that correspond to lesion regions.

Dataset	Cases	Total Frames	Split Ratio	Size Range
Train	10	97/223	47/47	0.3–54.3
Validate	5	58/139	28/29	0.2–75.1
Test	5	53/115	25/24	0.5–45.8
