Abstract
An embodiment of a visual search system includes at least one imaging device, each imaging device operable to capture a corresponding image, a feature extraction device coupled to each imaging device, each feature extraction device operable to generate feature descriptors from the image received from the corresponding imaging device. A descriptor encoding device is coupled to each feature extraction device and operable to generate compressed feature descriptors from the received feature descriptors. An application processor is coupled to each descriptor encoding device. The application processor is operable to process the received compressed feature descriptors to generate output information as a function of the processed compressed feature descriptors.
