Object detection device

Abstract

To provide an object detection device which facilitates learning.SOLUTION: In a new model generation device, an object extraction existing model 4 is a neural network model learned so as to extract an object from an object image having one or more objects in the background. Extraction object acquisition means 2 acquires object images with different backgrounds (different background object images). An object is extracted by giving the object images with the different backgrounds to the object extraction existing model 4, and extracted object information is obtained. Learning data generation means 6 generates learning data on the basis of the different background object images and the object information. Additional learning means 8 performs additional learning of the object extraction existing model 4 on the basis of the generated learning data. Thus, an object extraction new model capable of accurately extracting an object from the different background object images can be generated without manually creating the learning data.SELECTED DRAWING: Figure 1
