image recognition

Image recognition refers to the recognition of objects or ther features in an image. This can be useful in day-to-day aplications, for example, labelling people in a personal photo collection, and also more life-critical situations such as looking for cancerous cells in X-rays.. It is also critical in autonomous vehicles identifying road markings, obstacles, other cars and pedestrians. A more controversial application is in CCTV surveliance, partcularly facial recognition, which can be used to track down criminals, but also to control citizens in authoritarian regimes. There are also potential problems of bias in both therapeutic and law-enforcement applications.
