Abstract: In some embodiments, a method inputs a frame sample of a video into a prediction network of a discriminator. The frame sample is analyzed to determine whether the frame sample includes burned-in caption text. When the frame sample is determined to include burned-in caption text, the method sends the frame to a recognition engine to perform a recognition process on the frame sample, performs the recognition process on the frame sample to recognize text in the frame sample, and outputs the text for a service to be performed for the video. When the frame sample is determined to not include burned-in caption text, the method bypasses the recognition engine and does not perform the recognition process on the frame sample.
