Governing Deep Learning Models

Understanding Computer Vision

Computer vision is a field of AI that teaches computers to interpret and understand visual information. It's similar to how humans use their eyes and brains to understand the world around them.

At its core, computer vision involves creating deep learning algorithms that can process and analyse digital images or videos. These algorithms can identify objects, recognise faces, read text and even understand complex scenes.

Although computer vision is a subset of deep learning, because of the types of data it processes and the use cases it is applied to, we believe it has different governance requirements compared to traditional deep learning.
