METHODS AND APPARATUS TO SPECIFY REGIONS OF INTEREST IN VIDEO FRAMES
First Claim
1. A method to specify a region of interest in a graphical presentation, the method comprising:
- determining an initial template region to represent the region of interest, a location of the initial template region based on a first point selected in the graphical presentation by a user;
determining a first modification to perform on the initial template region in response to a second point selected in the graphical presentation by the user, the first modification at least one of selected by the user or corresponding to a default modification;
detecting the second selected point in the graphical presentation, the second selected point at least one of outside or inside the initial template region, but not substantially on a boundary defining the initial template region; and
reshaping the initial template region toward the second selected point, the reshaping corresponding to the first modification, the reshaping being performed in response to detecting the second selected point without also requiring the user to select any point substantially on the boundary defining the initial template region to initiate the reshaping.

Abstract
Methods and apparatus to specify regions of interest in video frames are disclosed. An example disclosed method comprises determining an initial template region to represent a region of interest whose location is based on a first point selected in a graphical presentation, determining a first modification to perform on the initial template region in response to a second point selected in the graphical presentation, detecting the second selected point in the graphical presentation, and reshaping the initial template region toward the second selected point, the reshaping corresponding to the first modification, the reshaping being performed in response to detecting the second selected point without also requiring the user to select any point substantially on the boundary defining the initial template region to initiate the reshaping.

13. An article of manufacture storing machine readable instructions which, when executed, cause a machine to:
-
determine an initial template region to represent a region of interest in a graphical presentation, a location of the initial template region based on a first point selected in the graphical presentation by a user; determine a first modification from a set of modifications to perform on the initial template region in response to a second point selected in the graphical presentation by the user, the first modification at least one of selected by the user or corresponding to a default modification; detect the second selected point in the graphical presentation, the second selected point at least one of outside or inside the initial template region, but not substantially on a boundary defining the initial template region; and reshape the initial template region toward the second selected point, the reshaping corresponding to the determined type of modification, the reshaping being performed in response to detecting the second selected point without also requiring the user to select any point substantially on the boundary defining the initial template region to initiate the reshaping. - View Dependent Claims (14, 15)

16. A system for marking a region of interest in a graphical presentation, the system comprising:
-
an output device to display the graphical presentation to a user; an input device for manipulation by the user to select points within the displayed graphical presentation; and a graphical user interface (GUI) processing element to; determine an initial template region to represent the region of interest in the graphical presentation, a location of the initial template region based on a first point selected in the graphical presentation by the user; determine a first modification from a set of modifications to perform on the initial template region in response to a second point selected in the graphical presentation by the user, the first modification at least one of selected by the user or corresponding to a default modification; detect the second selected point in the graphical presentation, the second selected point at least one of outside or inside the initial template region, but not substantially on a boundary defining the initial template region; and reshape the initial template region toward the second selected point, the reshaping corresponding to the determined type of modification, the reshaping being performed in response to detecting the second selected point without also requiring the user to select any point substantially on the boundary defining the initial template region to initiate the reshaping. - View Dependent Claims (17, 18, 19, 20)
