Classification: CPC G  H | IPC G  H

Claim 0:
1. A method comprising:
obtaining, by pixel sensors in a first integrated circuit layer and that are grouped based on position into pixel sensor groups, pixel information;
performing, by image processing circuitry groups in a second integrated circuit layer in electrical communication with the first integrated circuit layer, image processing operations on the pixel information from a corresponding pixel sensor group to provide processed pixel information;
performing, by neural network circuitry groups in a third integrated circuit layer in electrical communication with the second integrated circuit layer, analysis for object detection on the processed pixel information from a corresponding image processing circuitry group, the third integrated circuit layer comprising circuitry that is configured to implement a recurrent neural network, the recurrent neural network being configured to receive the pixel information regarding objects detected by all of the neural network circuitry groups and detect objects sensed across multiple ones of the pixel sensor groups; and
outputting information that indicates results of the analysis for object detection by the neural network circuitry groups,
wherein the first integrated circuit layer is stacked on the second integrated circuit layer and the second integrated circuit layer is stacked on the third integrated circuit layer.
