Abstract: A video processing device includes a foreground region estimation unit that determines whether a pixel of an input image is a foreground or a background, and a blinking correction unit that determines, for a target pixel on which a foreground and a background have been switched, whether switching between the foreground and the background is a color change in the foreground or in the background by using a lookup table capable of determining whether switching is in the foreground or in the background from a temporal change of a pixel value, and corrects a result of determination as to whether it is the foreground or the background that has been performed for the target pixel in a case where the switching between the foreground and the background is the color change in the foreground or in the background.

Abstract: An information processing device includes an extraction unit, an inverse sampling unit, a mapping unit, a generation unit, and a correction unit. The extraction unit is to extract a first feature value of a first image. The inverse sampling unit is to generate a second image having a resolution lower than that of the first image based on the first image and first information indicating a lighting environment different from that of the first image. The mapping unit generates a vector representing a latent space based on the second image. The generation unit is configured to generate a second feature value of a third image having a resolution higher than that of the second image based on the vector. The correction unit is configured to generate a fourth image obtained by correcting the third image based on the first feature value and the second feature value.

Abstract: It is possible to inhibit deterioration of extraction precision of a subject and reliably extract the subject even when colors of the subject and a background are the same or similar. An image processing device 1 includes an input unit 11 configured to input a first invisible light image of only a background in which a subject is not included and a second invisible light image in which the subject and the background are included and a subject region extraction unit 15 configured to calculate a difference between a pixel value of each pixel of the second invisible light image and a pixel value of a corresponding pixel of the first invisible light image, determine whether the pixel is in a subject region or a background region in accordance with whether the difference is equal to or greater than a predetermined threshold, and extract the subject region from the second invisible light image.

Abstract: Accurate and rapid identification can be performed even when feature vectors of input pixels and background pixels are close.
