Abstract:
A projection system of the present disclosure includes: a flying object having an exterior body, a flying device that causes the exterior body to fly, and an image capturing device that captures an image; a projection device that projects a capture-dependent image on the exterior body, the captured-dependent image depending on the image; and a controller that causes the projection device to project the capture-dependent image.
Abstract:
An image coding apparatus is an image coding apparatus which encodes a plurality of to-be-displayed images forming video by using inter prediction. The image coding apparatus includes an obtaining unit that obtains a reference-specific image which is an image different from the plurality of to-be-displayed images or different from a plurality of reconfigured images obtained by reconfiguration of the plurality of to-be-displayed images and which is an image used as an image that is specific to reference for the inter prediction, and an encoding unit that encodes one or more to-be-displayed images among the plurality of to-be-displayed images by referring to the reference-specific image as a reference image for the inter prediction.
Abstract:
In a coding method, a background image is extracted from a target frame included in a moving image (S11), a plurality of kinds of pieces of metadata indicating a feature of at least one object included in the target frame are extracted from the target frame (S12), the plurality of kinds of pieces of metadata are hierarchically disposed in each kind (S13), and coded information is generated, the coded information including background image information specifying the background image and meta-information indicating a part of or all the pieces of metadata corresponding to a hierarchy selected from the plurality of kinds of pieces of metadata (S14).
Abstract:
Provided is a prediction image generation method for generating a prediction image of a current block, the prediction image generation method including: an extraction step of extracting a plurality of first feature points each of which has a local feature quantity, the plurality of first feature points being included in a reconstructed image; a search step of searching a corresponding point from the plurality of first feature points, the corresponding point having a local feature quantity similar to a local feature quantity of a second feature point corresponding to the current block, a relationship between the corresponding point and the second feature point being expressed by information including a non-parallel translation component; and a generation step of generating the prediction image from the reconstructed image based on the relationship.
