Title: IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM
Abstract:
[Problem] To provide an image processing device with which it is possible to extract an object even in an image in which the object and a part of the background change in a linked manner. [Solution] An image processing device having: a storage means for storing, as background information, feature amount information for each pixel constituting the background of an image that includes the object; and a control means for, on the basis of the background information, extracting the object from the image in which the object and a part of the background change in a linked manner. The control means has: a calculation unit for calculating the feature amount of each pixel; a change region extraction unit for extracting a change region; an identification unit for identifying the image from the start of the change until the end; a determination unit for determining the similarity between the calculated feature amount and the feature amount of the background information using the pixels of an identified image; an update unit for, when a nonsimilar pixel is contained in a change region of the identified image, registering the feature amount information for the pixel in the background information; and an object extraction unit for extracting the object on the basis of the updated background information.
