Abstract
Techniques for direct local binary pattern (LBP) generation are presented. An image sensor for LBP generation includes a variable reference signal generator and a sensor pixel array that can generate events based on optical signals on the sensor pixel array and a reference level from the variable reference signal generator. The image sensor also includes an address encoder that can encode the addresses of the sensor pixels that generate events, and a binary image generator that can create a binary image based on the addresses of the sensor pixels that generate the events at the reference level. The image sensor may also include a local binary pattern generator configured to determine local binary pattern labels for image pixels whose binary value changes from a first binary image at a first reference level to a subsequent second binary image at a next reference level.
