Abstract: A non-transitory computer-readable recording medium has recorded thereon a computer program for face direction estimation that causes a computer to execute a process including: generating, for each presumed face direction, a face direction converted image by converting the direction of the face represented on an input image into a prescribed direction; generating, for each presumed face direction, a reversed face image by reversing the face represented on the face direction converted image; converting the direction of the face represented on the reversed face image to be the presumed face direction; calculating, for each presumed face direction, an evaluation value that represents the degree of difference between the face represented on the reversed face image and the face represented on the input image, based on the conversion result; and specifying, based on the evaluation value, the direction of the face represented on the input image.

Abstract: A processor generates a first road surface image from an image at a first time captured by an imaging device mounted on a moving body, and generates a second road surface image from an image at a second time after the first time. Next, the processor determines direction information depending on a direction of travel of the moving body between the first time and the second time from an amount of turn of the moving body between the first time and the second time. Then, the processor determines a relative positional relationship between the first road surface image and the second road surface image by using the amount of turn and the direction information, and determines an amount of travel of the moving body between the first time and the second time on the basis of the relative positional relationship.

Abstract: From plural observation features of a time series acquired by observing movements of a person, plural candidate segments are decided of a target action series containing plural respective actions expressing plural movements. Each of the plural candidate segments is divided into each action segment that is a time segment of the action, a likelihood corresponding to each of the plural actions computed for each of the action segments is normalized by action segment, and as an evaluation value a representative value is computed of normalized likelihood corresponding to each of the action segments selected from out of all of the respective action segments in the candidate segments based on an order of actions in the target action series. Being the target action series is determined in cases in which the evaluation value exceeds a common threshold.
