An image processing apparatus includes a detection unit configured to detect at least one identical object or at least one object of an identical type from images captured by a plurality of imaging apparatuses, a selection unit configured to select at least one object from among at least one detected object based on color information of each object, and a determination unit configured to determine color correction information related to a plurality of the imaging apparatuses based on color information of at least one selected object. The image processing apparatus enables restricting the degradation of the color matching accuracy.

Image processing apparatus, image processing method, and recording medium

There is provided with an image processing apparatus. An evaluation is set for each of the pairs. The evaluation is set based on at least one of the number of feature points in the first image where local feature amounts are similar to a local feature amount at one of the pair or the number of feature points in the second image where local feature amounts are similar to a local feature amount at one of the pair, in such a manner that the smaller the number of feature points, the higher the evaluation. A similarity between the first image and the second image is determined using a RANSAC method. A pair having a high evaluation is used with priority in derivation of a function for transforming coordinates using the RANSAC method.

Image processing apparatus, image processing method, and storage medium

A tint of an object according to a second image capturing device is corrected by a first parameter for correcting a tint of a second object that the second image capturing device captured in a first time zone to a tint of a first object that a first image capturing device captured in a first time zone. If a third object captured by a third image capturing device corresponds to the first object, a parameter for correcting a tint of the third object to the tint of the first object is used for correcting a tint of an object according to a third image capturing device. If the third object corresponds to the second object, the first parameter and a third parameter for correcting the tint of the third object to the tint of the second object is used for the foregoing tint correction.

A feature point is extracted from an input image including an image region for which depth values of pixels change consecutively. A transformation that normalizes depth values of pixels of a vicinity of the feature point with respect to a region of at least a portion of the input image is set as a normalization transformation, and an image for a feature amount calculation is generated by performing the normalization transformation on a pixel position of the feature point. A feature amount is calculated from the image for the feature amount calculation.

Depth normalization transformation of pixels

To obtain a clustering result which is less unnatural to the user, a data processing apparatus clusters at least one data arranged in time-series; generates, if new data is added, a reference value for defining a group division criterion in the clustering using at least one existing data that exists forward of the new data in time-series after a forward boundary; and determines based on the reference value whether a group division boundary exists between the new data and existing data positioned immediately before the new data.

This invention suppresses bloating of indices for an image search. To accomplish this, when a target image to be registered is given, an apparatus described in this specification executes partial image search processing using the target image to be registered as a query image. As a result, if a corresponding image is found, and an already registered image includes the query image, the target image to be registered is registered as an image linked to the already registered image.

Image search apparatus and control method thereof

An information processing apparatus includes first and second position acquiring units which respectively acquire a position metadata piece from a target data piece and position metadata pieces from plural data pieces different from the target data piece. A target acquiring unit acquires target metadata pieces other than the position metadata pieces from the other data pieces, and an analysis unit analyzes a distribution of the target metadata pieces based on positions indicated by the position metadata pieces acquired from the other data pieces. An assignment unit assigns to the target data piece a target metadata piece that has a value related to the target data piece, the target metadata piece being selected from among the analyzed target metadata pieces, based on the distribution and the position indicated by the position metadata piece acquired from the target data piece.

Information processing apparatus, information processing method and program therefor

Information processing in which a position metadata piece is acquired from a target data piece, the position metadata piece indicating a position. Position metadata pieces are acquired from a plurality of other data pieces different from the target data piece. Target metadata pieces other than the position metadata pieces from the other data pieces are acquired, a distribution of the target metadata pieces is analyzed based on positions indicated by the position metadata pieces acquired from the other data pieces, and a target metadata piece that has a value related to the target data piece is assigned to the target data piece, the target metadata piece being selected from among the analyzed target metadata pieces, based on the distribution and the position indicated by the position metadata piece acquired from the target data piece.
