While our Cloud Vision montaging workflow has yielded highly robust results across the majority of broadcasts we've tested it on, it does result in some reduced accuracy in edge cases, such as the Congolese broadcast below in which it fails to discern the blurry-pixelated-black-on-green chyron text. To be fair, however, even to a human it is extremely difficult to fully discern what the text says.
