A moving object detection device (100) includes a window setting unit (102) configured to set a window having a predetermined volume in a video, an orientation of spatial intensity gradient calculation unit (104) configured to calculate, for each pixel included in the window, an orientation of spatial intensity gradient, a spatial histogram calculation unit (106) configured to calculate a spatial histogram that is a histogram of the orientation of spatial intensity gradient within the window, an orientation of temporal intensity gradient calculation unit (108) configured to calculate, for each pixel included in the window, an orientation of temporal intensity gradient, a temporal histogram calculation unit (110) configured to calculate a temporal histogram that is a histogram of an orientation of temporal intensity gradient within the window, and a determination unit (112) configured to determine whether or not the moving object is included within the window based on the spatial histogram and the temporal histogram. |
