Abstract: A luminance variation (dI) pertaining to each pixel is calculated (21) using a plurality of captured images obtained by image capturing under different illumination conditions, a texture variation (dF) pertaining to each pixel is calculated (22) using a plurality of captured images obtained by image capturing at different time points, and a subject region is extracted (23) based on the luminance variation (dI) and the texture variation (dF). A variation in the texture feature (F) pertaining to each pixel between the images is calculated as the texture variation (dF). The subject can be extracted with a high accuracy even when there are changes in the ambient light or the background.

Abstract: A gesture judgment device includes a reference part detection unit that outputs reference part information indicating a reference part region, a movement extraction unit that outputs movement information indicating a movement region, a reference part disappearance judgment unit that generates a reference part disappearance information, a timing judgment unit that judges whether first timing indicated by the reference part disappearance information and second timing of occurrence of a frame in which the movement region overlaps with the reference part region indicated by the reference part information are synchronized with each other or not and outputs a timing judgment result as the result of the judging, and an operation judgment unit that judges contents of a gesture operation performed by an operator based on the timing judgment result and the movement information.

Abstract: Provided are a gesture recognition device, a gesture recognition method and an information processing device for making it possible to quickly recognize a gesture of a user. The gesture recognition device includes a motion information generator that generates body part motion information by performing detection and tracking of the body part, a prediction processor that makes a first comparison of comparing the generated body part motion information with previously stored pre-gesture motion model information and generates a prediction result regarding a pre-gesture motion on the basis of a result of the first comparison, and a recognition processor that makes a second comparison of comparing the generated body part motion information with previously stored gesture model information and generates a result of recognition of the gesture represented by a motion of the detected body part on the basis of the prediction result and a result of the second comparison.

Abstract: An information display device includes a display control unit, a gesture detection unit, a gesture identification unit that makes identification of an operator's gesture based on gesture information and outputs a signal based on a result of the identification, a distance estimation unit that estimates a distance between the operator and a display unit, and an identification function setting unit that sets gestures identifiable by the gesture identification unit so that the number of gestures identifiable by the gesture identification unit when the estimated distance is over a first set distance is smaller than the number of gestures identifiable by the gesture identification unit when the estimated distance is less than or equal to the first set distance.
