This raises the fascinating question of whether future analyses could combine Google's Cloud Video AI API's OCR with traditional perceptual hashing, color and spatial histograms and other similarity metrics to visually cluster all images matching a particular query to see if there are particular images the channels turn to more frequently to illustrate specific stories.
