An image processing device includes: a feature extractor which extracts features of pixels from an input image and an input image of a different time; a quantization unit which reduces the number of gradations of features extracted by the feature extractor; a learning unit 107 which learns combinations of the features of pixels through a machine learning algorithm that performs nonlinear identification and constructs a network according to machine learning; an LUT generator 109 which generates an LUT that replaces arithmetic operations of the network constructed by the learning unit 107; a foreground region estimator 103 which rapidly estimates similarity of each pixel of the input image to a foreground by referring to the LUT generated by the LUT generator 109; and a boundary corrector 121 which classifies regions similar to the foreground estimated by the foreground region estimator 103 into the foreground, a background, and an unclassified region including boundary pixels of the foreground and the background and performs boundary correction only on the unclassified region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video processing device, video processing method, and video processing program","description":"Accurate and rapid identification can be performed even when feature vectors of input pixels and background pixels are close.
