Our algorithm, DejaVuAI, is useful as a stand-alone technology for image comparison and search, or could be paired with other databases and analytics to achieve drastic efficiency and accuracy for image recognition. This new algorithm is much faster than methods for finding identical and similar images based on feature recognition (SIFT, etc.) and Artificial Intelligence/Machine Learning (AI/ML). Applications include: Reverse Image Search, Identification, Product Recognition, and Logo Recognition.
