Patent ID: 11967121
Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 4:
5. A difference detection device comprising
a processor;
a storage medium having computer program instructions stored thereon, when executed by the processor, perform to:
based on association among a first image and a second image captured at different times and illustrating a substantially identical space and encoding information of each of the first image and the second image, detect difference between a third image and a fourth image captured at different times and illustrating a substantially identical space,
wherein the encoding information is information acquired from data including the first image being encoded and data including the second image being encoded, after transform processing is executed in encoding processing executed on the first image and the second image,, wherein the association is association of output values from neural networks at a previous stage, which have executed learning based on any of the first image, the second image, and the encoding information; and
a neural network at a later stage, which has executed learning so that each output value approaches a first value when it is determined that the first image and the second image have difference and the output value approaches a second value when it is determined that the first image and the second image have no difference.
