Perspective warp

摘要

Systems and methods are provided that allow a user to specify one or more areas of, e.g., a digital image, upon which perspective manipulation is to be applied. Once the one or more areas of the digital image have been specified, the user may specify one or more portions within the one or more areas, such as points, lines, etc., as being constrained in some manner. Thereafter, the user is able to manipulate perspective within the one or more specified areas in an intuitive and efficient manner.

主权项

1. A method, comprising:
receiving an indication of a portion of digital media to undergo perspective manipulation; providing a user interface arising from the indicated portion of the digital media through which the perspective manipulation is to be performed; identifying a sub-portion of the digital media that is within the indicated portion of the digital media and that is to remain unchanged by the perspective manipulation, wherein the sub-portion of the digital media is identified based on information received via the user interface regarding at least one constraint associated with the indicated portion of the digital media; updating the user interface to include a visual indicator identifying the sub-portion of the digital media that is to remain unchanged by the perspective manipulation; performing the perspective manipulation of the indicated portion of the digital media in accordance with user input and the received information regarding the constraint; and displaying a real-time preview of the perspective manipulation such that the identified sub-portion of the digital media is not changed in the real-time preview.
