Face Recognition Performance

Sighthound is a leader in deep learning, specializing in building intelligent convolutional neural networks that can run real time in resource-constrained environments, including on embedded systems. Sighthound's facial recognition system leads the world, with measured accuracy of 99.2% against PubFig200, some ten percentage points clear of other commercial or academic methods.

Our model uses 3.8 million images, or about 1.5% of the number of images Google lists for training FaceNet. Our pipeline uses only a single crop of the face. Crops are partial areas of training images used to enhance results. However each additional crop slows down performance in recognition tasks, meaning the models are optimized for test-taking, not for real world use. Sighthound is not specifically tailored to verification tasks, and the same model can be used with industry-leading performance on identification tasks.

The result is that Sighthound’s software is highly accurate, robust to a variety of real world use cases and runs in real time.
