Abstract: Some embodiments provide a method for selecting a portion of an image. The method identifies edges in the image. The method defines a border about the portion of the image by using the identified edges. The method represents the border as a deformable curve. In some embodiments, defining the border includes detecting a cursor moving over the image and defining the border along identified edges in the vicinity of the cursor. In some embodiments, the method searches for edges in the vicinity of the cursor and snaps the border to the edges. Identifying the edges of the image includes performing an edge detection algorithm in some embodiments. Identifying the edges further includes performing a de-noise algorithm in some embodiments. In some embodiments, the parametrizable curve is a bezier spline.

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.

Abstract: The disclosed implementations relate generally to improved workflows for color correcting digital images. In some implementations, a method of correcting images includes: presenting a user interface on a display device, the user interface including a display area; presenting a digital image in the display area; overlaying a correction interface on the digital image; and performing a correction operation on at least a portion of the digital image in response to a user interaction with the correction interface, where the correction operation is performed with real-time responsiveness.
