End-to-end deepfake detection pipeline combining input validation, frame preprocessing, neural network inference, and confidence scoring to classify media as authentic or synthetic. User uploads image or video, which flows through validation and normalization stages before model inference computes a deepfake confidence score. The system branches on detection threshold to output FAKE or REAL classification with error handling for invalid inputs and inference failures. Fork this flowchart to customize preprocessing steps, swap detection models, or adjust confidence thresholds for your media authentication use case.
