This invention provides an object tracing apparatus that traces an object in a video obtained by an image capturing apparatus, comprising a tracking unit that tracks the object in a frame in the video and obtains track data indicating consecutive appearances of the object, and a tracing unit that generates trace information indicating which object ID each track ID belongs to, by associating a track ID obtained via tracking by the tracking unit with an object ID for uniquely identifying an object, wherein the tracing unit, on a basis of a coexistence possibility relating to imaging time between a track ID associated with one or more existing object IDs and target track data without an associated object ID, determines which object ID the target track data belongs to.

Object tracing apparatus, method for same, and non-transitory computer-readable storage medium

There is provided with an information processing device. A defect detecting unit detects a defect of an object in an input image. An extracting unit extracts a feature amount pertaining to a partial image of the defect from the input image, on the basis of a result of detecting the defect. An attribute determining unit determines an attribute of the defect using the feature amount pertaining to the partial image of the defect.

Information processing device, information processing method, and storage medium

An apparatus includes a display control unit, a receiving unit, an adjusting unit, and a determination unit. The display control unit is configured to display an image showing a result of detection of a defect from a captured image of a structure on a display device. The receiving unit is configured to receive an operation to specify part of the displayed image as a first region and an operation to give an instruction to correct at least part of the detection data corresponding to the first region. The adjusting unit is configured to adjust a parameter to be applied to the first region according to the instruction. The determination unit is configured to determine one or more second regions to which the adjusted parameter is to be applied from a plurality of segmented regions of the image.

Information processing apparatus, information processing method, and recording medium

An information processing apparatus includes a map creation unit configured to create a defocus map corresponding to a captured image of a subject, an object setting unit configured to set a recognition target, and a determination unit configured to determine, based on the defocus map, whether the recognition target is recognizable in the image.

Information processing apparatus, information processing method, and storage medium for determining whether a captured image of a subject is suitable for recognition processing

Some embodiments are directed to, by a simple operation, appropriately displaying an image to which attention is paid. An information processing apparatus according to some embodiments is an information processing apparatus for performing display for measuring a width of a region in an image of an inspection target object, the information processing apparatus including an acquisition unit configured to acquire a bending position where a bend of a line approximating the region from the image satisfies a predetermined condition, and a display control unit configured to display, in an aligned manner in a predetermined direction, a plurality of partial images obtained by dividing the image based on the bending position.

Information processing apparatus, information processing method, and storage medium

On the basis of a difference between first distribution regarding target task learning data as a plurality of learning data which belongs to a first category of a first task as a target task and second distribution regarding a plurality of learning data which belongs to the first category of source task learning data as learning data which belongs to the first category of a second task different from the first task, a transformation parameter for transforming the source task learning data is adjusted, the source task learning data is transformed based on the adjusted transformation parameter, and a classifier regarding the first task is generated based on the transformed source task learning data and the target task learning data.

Information processing apparatus and information processing method for generating classifier using target task learning data and source task learning data, and storage medium

Embodiments of the present invention are directed to learning of an appropriate dictionary which has a high expression ability of minority data while preventing reduction of an expression ability of majority data. A dictionary generation apparatus which generates a dictionary used for discriminating whether data to be discriminated belongs to a specific category includes a generation unit configured to generate a first dictionary based on learning data belonging to the specific category and a selection unit configured to estimate a degree of matching of the learning data at each portion with the first dictionary using the generated first dictionary and select a portion of the learning data based on the estimated degree of matching, wherein the generation unit generates a second dictionary based on the selected portion of the learning data.

Dictionary generation apparatus, evaluation apparatus, dictionary generation method, evaluation method, and storage medium for selecting data and generating a dictionary using the data

An image processing device includes: a determination unit configured to determine, based on a feature amount of input image data, a category of the input image data and a score representing confidence of the category, with a classification model; a display unit configured to display an image representing the input image data and the determined category of the input image data; an acceptance unit configured to accept a correction of the displayed category from a user; and an updating unit configured to update the classification model, based on the correction of the category.

Device that updates recognition model and method of updating recognition model

An apparatus according to the present disclosure acquires a display condition for displaying at least a part of target data as a display image on a display unit, determines, in a case where the display image is changed, whether to store the display condition according to a changed display image in a storage unit, based on an index relating to the change of the display image, and stores, in a case where the display condition is determined to be stored, the display condition according to the changed display image in the storage unit.

An information processing apparatus includes a reception unit configured to receive an input specifying a position of a detection target included in an image, an acquisition unit configured to acquire a storage amount of training data including a pair of information indicating the image and information indicating the position specified by the input, a training unit configured to train a training model to detect the detection target from the image based on the stored training data, and a display control unit configured to control a display unit to display the storage amount, and a reference amount of the training data set as an amount of the training data necessary for the training unit to train the training model, in a comparable way.
