An image retrieval apparatus acquires an image to be processed, the image to be processed including at least one article. The image retrieval apparatus specifies, as an association image, a product image of a product having an evaluation value that has a predetermined relationship with an evaluation value of the article included in the image to be processed, from among product images of a plurality of products each belonging to a particular category, the particular category being different from a category to which the article included in the image to be processed belongs. The image to be processed and the specified association image may be output in association with each other.

An image searching apparatus includes processing circuitry configured to calculate an evaluation value that indicates a preference of a customer, by using an image feature amount based on an image; and identify an image to be recommended to the customer by using the calculated evaluation value, from among images of a plurality of articles.

Image searching apparatus, printed material, and image searching method

An information processing system includes circuitry configured to store, in a memory, one or more feature value patterns associated with appearance attribute of one or more groups of persons calculated from a plurality of acquired image data using machine learning, in which each one of the groups assumed to have a unique group value being different for each one of the groups, receive image data of a target person input as analysis target data, analyze an appearance attribute of the target person in the image data using the one or more feature value patterns associated with the appearance attribute of the one or more groups stored in the memory, and output a response corresponding to an analysis result of the appearance attribute of the target person.

Image attribute processing system, image attribute processing apparatus, and method of processing image attributes

An image processing apparatus includes a skin area extraction unit that extracts a skin area from image data, a chromaticity computation unit that computes hue information and saturation information of the skin area, a hue conversion unit that converts the hue information so that the hue information is in agreement with target information, a reception unit that receives a change instruction to change the saturation information, a parameter determination unit that determines a conversion parameter based on the change instruction, and a saturation conversion unit that converts the saturation information based on the conversion parameter.

An image processing apparatus includes an image information acquisition unit acquiring average brightness of image data and cumulative frequency distribution of pixels related to gradation of the image data; a conversion range determination unit acquiring a conversion threshold value from the average brightness based on a previously set relationship and determining a gradation conversion range where the gradation of the image data is to be converted based on a gradation where a cumulative frequency corresponds to the conversion threshold value in the cumulative frequency distribution; and a gradation conversion unit converting the gradation of the image data in the gradation conversion range.

Image processing apparatus, image processing system, image processing method, and recording medium converting gradation of image data in gradation conversion range to emphasize or reduce shine appearance

An image processing apparatus includes a skin information obtaining unit that extracts a skin area from an image and obtains skin information from the skin area; an independent component extracting unit that extracts independent components constituting the skin area from the skin information; and a bias calculation unit that calculates, based on the independent components, a bias representing color information of a light source used to illuminate the skin area when the image is captured.
