Table 1.

Outputs of I2N.

Term	Description
True SDEEp	Annotator marked a SDEEp as a true if captured images contain food items. I2N provides the total number of true SDEEp and its corresponding time. This validates the SDEEp.
False SDEEp	Annotator marked a SDEEp as false if the captured images of a SDEEp do not contain any food items. This helps to remove false SDEEp from the annotated record.
