For people thinking it detected the decoy text. It did not. It was the text I entered myself. Here are the thinking steps:
Inspected video metadata, extracted frames, and analyzed content
Detected and analyzed periodicity in stereogram image data
Blurred, downsampled, and analyzed image frames
Computed frame pixel shifts and cross-correlation
Checked OpenCV installation, optimized and analyzed optical flow processing
Analyzed motion for text
Estimated vertical displacement and processed image flow
Refined text extraction
Processed optical flow and analyzed image
