Abstract: A learning model construction device (3A) according to the present disclosure includes: a plurality of learning units (354-k) that constructs a respective plurality of learning models by using a respective plurality of loss functions different from each other on the basis of teacher data in which image data indicating a learning image is associated with a true value of a scale of the learning image; a plurality of verification units (355-k) that respectively calculates, for an optimal verification image, a plurality of estimated values; a plurality of correlation calculation units (356-k) that calculates respective correlations of the true value with the plurality of estimated values of the scale; and an optimal learning model selection unit (357) that selects an optimal learning model that is a learning model of which a corresponding one of the correlations is the highest.

Abstract: An image processing device (10) according to the present disclosure includes a feature point detection tracking unit (12) that detects a feature point in a first frame that is a frame at a first time, tracks the feature point from the first time to a second time later than the first time, and calculates a two-dimensional vector indicating a motion of the feature point, a feature point movement amount calculation unit (13) that calculates a movement amount of the feature point based on the calculated two-dimensional vector, and a determination unit (14) that determines whether the calculated movement amount is equal to or greater than a predetermined threshold value, and outputs a second frame as the clipped frame, the second frame being a frame at the second time, when the movement amount is determined to be equal to or greater than the threshold value.

Abstract: A region correction device (1) according to the present disclosure includes: an input unit (41) that receives an input of prediction region information indicating a prediction region (PA) indicating an image of a predetermined subject, the prediction region (PA) being detected from a captured image obtained by imaging the predetermined subject; a line segment extraction unit (42) that extracts a line segment on the basis of a contour of the prediction region (PA) indicated by the prediction region information; a correction unit (43) that corrects the prediction region (PA) on the basis of the line segment; and an output unit (44) that outputs corrected prediction region information indicating a corrected prediction region, the corrected prediction region being the prediction region (PA) that has been corrected.
