Abstract
A method of detecting and recognizing faces using a light field camera array is provided. The method includes capturing multi-view color images using the light field camera array; obtaining a depth map; conducting light field rendering using a weight function comprising a depth component and a sematic component, where the weight function assigns a ray in the light field with a weight; and detecting and recognizing a face.
