Abstract: Some embodiments provide a method of selecting a section of interest in an image that includes numerous pixels. the method draws a curvilinear boundary about the section of interest. From the curvilinear boundary, the method generates a two-dimensional transition tunnel region about the section of interest.

Abstract: Some embodiments provide a method of color correcting an image. Some such embodiments provide (1) a display area for displaying a modifiable graph correlating a first color attribute of the image to a set of second color attributes and (2) at least one tool that adjusts the graph in order to adjust color attributes in the image. The graph adjustment tool of some embodiments is a set of control points that specify the color correction adjustment over a parameterized curve representation of the graph. In some embodiments, the graphs are rasterized curves that are adjusted through the use of a Gaussian manipulator. The Gaussian manipulator distributes a second color attribute adjustment over a set of first color attribute values according to a Gaussian distribution. Moreover, some embodiments allow for the selective switching between the parameterized and rasterized curves or the control points and the Gaussian manipulator.
