  • Patent number: 11615132
    Abstract: Low-dimensional feature values with which semantic factors of content are ascertained are generated from relevance between sets of two types of content. Based on a relation indicator indicating a pair of groups indicating which groups are related to first types of content groups among second types of content groups, an initial feature value extracting unit 11 extracts initial feature values of the first type of content and the second type of content. A content pair selecting unit 12 selects a content pair by selecting one first type of content and one second type of content from each pair of groups indicated by the relation indicator. A feature value conversion function generating unit 13 generates feature conversion functions 31 of converting the initial feature values into low-dimensional feature values based on the content pair selected from each pair of groups.

  • Publication number: 20190387166
    Abstract: Provided is an image processing apparatus which receives moving image data obtained while a camera is moved, estimates a camera movement trajectory, selects, from among points on the estimated camera movement trajectory, a plurality of points satisfying a predetermined condition, and extracts, from the received moving image data, image data captured at the selected plurality of points. The image processing apparatus generates and outputs moving image data that have been reconfigured on the basis of the extracted image data.

  • Patent number: 10331953
    Abstract: Provided is an image processing apparatus which is connected to and accessible to a database storing a plurality of pieces of previously prepared reference data, and which stores at least one piece of individual data having an image captured by the user in association with the information regarding the food/beverage contained in the captured image. The image processing apparatus compares information of the food/beverage in the captured image with the reference data stored in the database and the individual data, and acquires the food/beverage information included in the reference data together with the reference image similar to the captured image, the food/beverage information associated with the captured image in the individual data, or the food/beverage information in the reference data or the individual data including the food/beverage information relating to the captured image.

  • Patent number: 9449226
    Abstract: To provide an information processing device for outputting estimated nutrition value information on at least one dish or a drink through simplified processing. The information processing device holds as reference information a captured image of at least one dish or a drink and nutrition value information set for the item of food or drink included in the image so as to be correlated to each other, receives an image including at least one dish or a drink, and retrieves a plurality of images similar to the image received from among the reference information held. Further, the information processing device calculates a statistic of a plurality of nutrition value information pieces correlated to the plurality of respective images retrieved, and outputs the statistic calculated.

  • Patent number: 6571023
    Abstract: An image processing method using multiple images includes the steps of imaging multiple differently focused images Im (m=1, . . . , n); deriving an identical equation based on superposition models realized between the multiple differently focused images Im and desired images I, obtaining a solution by substituting multiple images Im and the functions Tmk and Tk of different focusing into the identical equation; performing an image process for generating desired image I based on this solution; and selectively generating a desired image I by controlling the function Tk.

  • Publication number: 20010013895
    Abstract: The object of this invention is to provide an apparatus for reconstructing, from a plurality of images that are focused differently, an arbitrarily focused image that is an image wherein the degree of blur at any depth is suppressed or intensified. A first filter for converting a first image that is in focus in a first portion based on a first blur parameter input from the outside, a second filter for converting a second image that is in focus in a second portion based on a second blur parameter input from the outside, a synthesizer for synthesizing the output of the first filter and the output of the second filter and generating an arbitrarily focused image, and a brightness compensator for performing brightness correction in image block units so that the brightness of the first image and of the second image become about the same, and supplying the images after brightness correction to the first filter and the second filter, are provided.
