There is provided with an image processing apparatus, for example, for image recognition. An extraction unit extracts a feature amount from a target image. An estimation unit estimates distribution of regions having attributes different from each other in the target image based on the feature amount.

Image processing apparatus, training apparatus, image processing method, training method, and storage medium

An image processing apparatus that tracks a target object by estimating a position of the target object on each of a plurality of images. A first estimating unit estimates the position of the target object in at least one of images. A second estimating unit estimates the position of the target object in at least one of images, wherein estimating accuracy of the position of the target object in the second estimating process is lower than the estimating accuracy in the first estimation process. A correcting unit corrects the position of the target object estimated by the second estimation process on a second image, based on the position of the target object estimated by the first estimation process on a first image. The second image is an image captured at a different time from the first image.

Image processing apparatus, method of tracking a target object, and storage medium

An image processing apparatus includes an image acquisition unit configured to extract an image from a video image, a history management unit configured to generate movement history of an object, a setting unit configured to set a search range in the image based on the movement history, and a tracking unit configured to detect a target object in the search range and associate a currently detected target object with a previously detected target object, to perform tracking on the target object.

Image processing apparatus, image processing method, and storage medium

An image processing apparatus includes an acquisition unit, a first detection unit, a selection unit, and a correction unit. The acquisition unit acquires an image including a target object having a plurality of parts. The first detection unit detects a candidate region of each of the plurality of parts of the target object included in the acquired image using a previously learned model. The selection unit selects, based on the candidate region detected by the first detection unit, a first part having relatively high reliability and a second part having relatively low reliability from among the plurality of parts. The correction unit corrects the model by changing a position of the second part based on the first part selected by the selection unit.

Image processing apparatus, image processing method, and storage medium to detect parts of an object

When a human skin region is detected, misdetection or detection failure is prevented. An image processing apparatus of the present invention acquires an image from which a human body skin region is to be extracted, and estimates a human body part region in the image. The image processing apparatus then estimates a skin attribute of the estimated human body part region and corrects the human body part region based on the estimated skin attribute. The image processing apparatus extracts the skin region from the acquired image based on the skin attribute of the estimated human body part region and the corrected human body part region.

Image processing method, image processing apparatus, and recording medium

An image retrieval apparatus includes a designation unit configured to designate a query area of an image based on a user's designation operation, a display unit configured to display an area where a local feature amount is difficult to be extracted in the query area designated by the designation unit as a feature non-extractable area, and a retrieval unit configured to retrieve, based on a local feature amount extracted from an area which is not displayed as the feature non-extractable area in the query area by the display unit, image feature data with which a local feature amount and the image are associated and which is stored in a storage device.

Image retrieval apparatus, image retrieval method, and storage medium

An information processing apparatus includes: a calculation unit adapted to analyze an image and calculate an intermediate value; a setting unit adapted to set a feature extraction region in the image, using the intermediate value; and an extraction unit adapted to extract a local feature of the feature extraction region, reusing the intermediate value used by the setting unit.

Local feature extraction apparatus, control method therefor, and computer-readable medium

A image processing apparatus extracts a plurality of feature points, comprising a local feature amount, from an inputted image, and a region information that relates to the feature point, identifies at least one of the plurality of feature points, associates the feature point thus identified with a feature point with a high relational degree between the feature point thus identified and a region that is denoted by the region information of the feature point thus identified, and registers the feature point thus identified and associated as an index of the inputted image.

Image processing apparatus and image retrieval method

An image processing apparatus executes smoothing processing (reduction conversion) of an input image to acquire a smoothed image (reduced image), acquires a normalization parameter for normalization from the smoothed image, and normalizes pixel values of the input image based on the normalization parameter.

Image processing apparatus, image processing method, and program

An image search apparatus, which determines a similarity between an input query image and a registered comparison destination image and searches an image similar to the query image, extracts a plurality of corresponding pairs of feature points in two images based on feature points selected from the both images. A coordinate transformation coefficient to execute a coordinate transformation process is decided so that coordinates of the feature point of one of the two images match coordinates of the feature point of the other image, in relation to each pair. Only if an amount of transformation of coordinates satisfies the constraint conditions designated in advance, the coordinate transformation process using the coordinate transformation coefficient is executed in relation to the plurality of pairs of feature points, and coordinates of the feature points after the transformation of one image are compared with coordinates of the corresponding feature points of the other image.

Image search with feature point transformation

An image processing method performs reduction processing on an input image to acquire a reduced image, extracts a feature point from a group of images including the input image and one or more of the reduced images, determines as a matched feature point the feature point extracted from a matching position in each of two or more images in the group of images, calculates a local feature quantity of the matched feature point determined by the determination unit, and registers the calculated local feature quantity as a local feature quantity of the input image.

Image processing apparatus, image processing method and program

An image processing apparatus extends the edge portion of an image in a prescribed range, detects, from the image, a plurality of feature points that each indicate a setting position of a local region, sets a local region corresponding to each of the feature points in the image on which region extension has been performed, and calculates a local feature amount corresponding to each feature point based on image information in the local region.
