An image processing apparatus extracts a foreground image corresponding to an object included in a processing image using a background image corresponding to the processing image, and generates the background image from the processing image. The image processing apparatus determines whether it is allowed to update the background image for use in the extraction, and based on a result of the determination, updates the background image for use in the extraction using the generated background image.

Image processing apparatus, image processing method, and storage medium

An object is to appropriately determine a color of a three-dimensional model of an object. In an image processing apparatus, based on the analysis of the three-dimensional model of the object, the determination method of a color for the portion, which corresponds to the object shape of the component constituting the three-dimensional model, is made different from that for the portion, which does not correspond to the object shape.

A file generation apparatus generates a file which includes material data used for generation of a virtual viewpoint image that is based on a multi-viewpoint image and type information for specifying a type of the material data, and outputs the generated file.

File generation apparatus, image generation apparatus based on file, file generation method and storage medium

The present invention provides a user with a user interface for enabling the user to efficiently perform an operation for generating a virtual viewpoint image for each imaging target subject to be imaged by a plurality of imaging apparatuses. An event information acquisition unit acquires information about an event subjected to virtual viewpoint image generation, and transmits the acquired event information to a user interface (UI) determination unit. The UI determination unit determines a UI to be generated by a UI generation unit based on the event information transmitted from the event information acquisition unit. The UI generation unit generates the UI determined by the UI determination unit. The user performs an input operation for generating a virtual viewpoint image according to the UI generated by the UI generation unit.

Information processing apparatus, method for controlling the same, and storage medium

An image processing apparatus generates, based on an input image, region information indicating a region including an object, determines, based on the region information, a region including an object to be transmitted, and transmits, based on the region information indicating the determined region, an image of the object and region information indicating the determined region.

In an image processing apparatus, three-dimensional shape data indicating a shape of an object is generated based on at least one of a plurality of images captured from different directions by a plurality image capturing devices. Color information indicating a color of each element of the three-dimensional shape data is generated based on the generated three-dimensional shape data and the plurality of images. The three-dimensional shape data and the color information are associated with each other and written to a storage unit as material data for generating a virtual viewpoint image corresponding to virtual viewpoint information indicating a virtual viewpoint.

Image processing apparatus, method and storage medium for generating a virtual viewpoint with reduced image data

An information processing apparatus that generates a three-dimensional model based on a plurality of camera images obtained using a plurality of cameras, performs: transforming, into two-dimensional coordinate points on a camera image, a plurality of representative coordinate points specified from one processing unit voxel of a plurality of processing unit voxels that are obtained by dividing a target three-dimensional space serving as a target of three-dimensional model generation; determining, by using transformation results of the plurality of representative coordinate points, a coordinate point on the camera image corresponding to an internal coordinate point of the one processing unit voxel; and generating the three-dimensional model based on the determined coordinate point on the camera image corresponding to the internal coordinate point of the one processing unit voxel.

To present relevant information about an object of interest to a viewer in an appropriate timing based on the display state of objects that appear in a video image. A video image processing apparatusprocesses the additional information including content data and relevant information about the respective objects. A display feature information calculation unitacquires frame data indicating the display state of an object to be displayed in each frame constituting video data and calculates display feature information about the object to be displayed in each frame. A frame evaluation unitevaluates a frame using an evaluation criteria relating to the degree of attention of the object within a frame based on the calculated display feature information. A display timing determination unitdetermines a frame at which displaying relevant information about the object is to be started in accordance with the frame evaluation result. A display data generation unitgenerates data for displaying relevant information about an object, and a superimpose unitsuperimposes the data with video data, and output the superimposed data to a display unit
