Image Recognition
Frame extractionTo generate spatial frames, we extract raw video frames from each video file. Confidence score calculationHere, we first examine how to calculate the frame-wise confidence score ({\widehat{p}}_{j}). We refer to this confidence score as the “max softmax score,” since it is derived from the maximum softmax probability. Now that we have established the process for generating a frame-wise confidence score, we can generate the clip-wise confidence score that is used in the confidence-based review. In the best case, the first (k) clips reviewed would be the (k) clips with the lowest accuracy.
