US 8,300,893 B2 · Methods and apparatus to specify regions of interest in video frames

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.

Dependent claims

A method to mark a region of interest in a graphical presentation, the method comprising:

determining a first shape to define the region of interest, the first shape being positioned to include a first point in the graphical presentation;
detecting selection of a second point in the graphical presentation, the second point not being associated with a boundary defining the first shape;
and
reshaping the first shape toward the second point to form a second shape to redefine the region of interest, the reshaping being performed in response detecting the selection of the second point.

1 more element

A tangible machine readable storage medium comprising machine readable instructions which, when executed, cause a machine to at least:

determine a first shape to define a region of interest in a graphical presentation, the first shape being positioned to include a first point in the graphical presentation;
detect selection of a second point in the graphical presentation, the second point not being associated with a boundary defining the first shape;
and
reshape the first shape toward the second point to form a second shape to redefine the region of interest, the machine to perform the reshaping in response to detecting the selection of the second point.

1 more element

A system for marking a region of interest in a graphical presentation, the system comprising:

an output device to display the graphical presentation;
an input device to select points within the displayed graphical presentation;
and
a processor to:
determine a first shape to define the region of interest, the first shape being positioned to include a first point in the graphical presentation using the input device;
detect selection of a second point in the graphical presentation using the input device, the second point not being associated with a boundary defining the first shape;
and
reshape the first shape toward the second point to form a second shape to redefine the region of interest, the processor to perform the reshaping in response to detecting the selection of the second point.
