Abstract
The image processing device includes a change area detection unit which detects a change area, where an object has changed compared to the first image, in the second image obtained by observing the same observed area as an observed area in the first image, an image correction unit which performs a correction process to make the change area in the second image smaller relative to a non-change area where the object has not changed, and an image pair output unit which outputs an image pair of the second image processed by the image correction unit and the first image.
Claims8
An image processing device comprising:
- a memory storing software instructions, and
- one or more processors configured to execute the software instructions to
- detect a change area, where an object has changed compared to a first image, in a second image obtained by observing a same observed area as an observed area in the first image;
- perform a correction process to make the change area in the second image smaller relative to a first non-change area where the object has not changed;
- and
- output an image pair of the corrected processed second image and the first image,
- wherein the one or more processors are configured to execute the software instructions to
- generate two deformed images by deforming object presence areas in two object presence images, which are images obtained from each of two observed images, in which one or more objects are present, and which correspond to the first image and the second image, based on an observation angle of each of the two observed images and a size of the object that appears in each of the two observed images, and
- generate a synthesized image by combining the two deformed images, determine a change of the object between the two object presence images using the synthesized image, and generate an image capable of identifying the determined change.

An image processing device comprising:
- a memory storing software instructions, and
- one or more processors configured to execute the software instructions to
- detect a change area, where an object has changed compared to a first image, in a second image obtained by observing a same observed area as an observed area in the first image;
- calculate a matching degree between the first image and the second image based on a size of a non-change area in the second image where the object has not changed;
- and
- output an image pair of the second image and the first image when the matching degree exceeds a predetermined value, wherein the one or more processors are configured to execute the software instructions to
- generate two deformed images by deforming object presence areas in two object presence images, which are images obtained from each of two observed images, in which one or more objects are present, and which correspond to the first image and the second image, based on an observation angle of each of the two observed images and a size of the object that appears in each of the two observed images, and
- generate a synthesized image by combining the two deformed images, determine a change of the object between the two object presence images using the synthesized image, and generate an image capable of identifying the determined change.
