An example of selecting responsible frames

Step 1: MaxPool the three frame feature matrices and yield the video feature matrix. Step 2: choose frame1 as the first responsible frame for it minimizing the difference between FScorevideo and FScoreframei. Step 3: add another frame to the responsible frame collection, whereas step 2 already chose one. Since the FScore difference between the responsible frame collections of frame1 and frame3 is the smallest, frame3 is picked as the second responsible frame. Example Figure 1 Schematic diagram of automatic stop of responsible frame selection. Note: RF_1: The first responsibility frame, and so on; When the model selects the video responsibility frame, it gradually rises from the initial malignant prediction value to RF_9 (0.93), from RF_10 starts to decline gradually, so the model is selected to RF_9 stop.
