Abstract

Provided are an image processing apparatus, an image processing method, and a storage medium that can determine an anomaly while reducing influence of an individual difference of images. The image processing apparatus includes: a first generation unit that generates a first estimation image including at least a predetermined region of an inspection target by using a part of an inspection image including the inspection target; a second generation unit that estimates a difference between the first estimation image and the inspection image to generate a second estimation image by using the part of the inspection image; a comparison unit that compares the first estimation image with the inspection image; and an output unit that outputs a comparison result obtained by the comparison unit, and the comparison unit compares a difference between the first estimation image and the inspection image with the second estimation image.

Dependent claims

An image processing apparatus comprising:

a processor;
a memory storing executable instructions that, when executed by the processor, causes the processor to perform as:
a first generation unit that generates a first estimation image including at least a predetermined region of an inspection target by using a part of an inspection image including the inspection target;
a second generation unit that estimates a difference between the first estimation image and the inspection image to generate a second estimation image by using the part of the inspection image;
and
a comparison unit that compares the first estimation image with the inspection image;
and
an output unit that outputs a comparison result obtained by the comparison unit,
wherein the comparison unit compares a difference between the first estimation image and the inspection image with the second estimation image,
wherein the inspection image includes a first region and a second region,
wherein the first generation unit generates the first estimation image of the second region by using an image of the first region in the inspection image,
wherein the second generation unit estimates a difference between the first estimation image of the second region and the image of the second region in the inspection image to generate the second estimation image by using the image of the first region in the inspection image, and
wherein the comparison unit compares a difference between the first estimation image of the second region and the image of the second region in the inspection image with the second estimation image.
