Claim 0:
1. An image processing method for an image processing apparatus comprising a hierarchical network that receives an image and outputs a feature quantity of the image, the image processing method comprising:
executing first learning processing of inputting a first data set selected from a first image group to the hierarchical network and of causing the hierarchical network to learn the first data set; and
executing, after execution of the first learning processing, second learning processing of inputting a second data set selected from a second image group having an identity different from an identity of the first image group to the hierarchical network and of causing the hierarchical network to learn the second data set, learning being performed in the second learning processing with a learning rate in a layer near an input side of the hierarchical network being set to be higher than a learning rate in a layer near an output side of the hierarchical network,
wherein the first data set and the second data set are common in a task as detection of a specific photographic subject,
wherein the identity of the first image group indicates the first data set is constituted by first medical images recorded in a first image database and the identity of the second image group indicates the second data set is constituted by second medical images recorded in a second image database.
