Embodiment Construction

[0062] Numerous details are set forth in the following description for purposes of explanation. However, one of ordinary skill in the art will realize that the present invention may be practiced without the use of these specific details.

[0063] Section 1. Overview

[0064] Some embodiments of the present invention provide a method for defining boundaries as a cursor scrolls over an image. In some embodiments, when an image editing application loads an image for display and editing, the application identifies the edges of the image. Before identifying edges, some embodiments apply a denoising algorithm to the image, thereby retaining only the most relevant edges in the image.

[0065] Some embodiments use edges to define boundaries for images. For example, in some embodiments, the method (1) identifies an edge located near a cursor moving on the image, and (2) locks the defined boundary to the nearby identified edge. In some of these embodiments, the method displays a sea...

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.

Description

technical field [0001] The present invention relates to image editing. In particular, the present invention relates to defining boundaries for images. Background technique [0002] Image editing applications (as well as video and other media editing applications) provide users with the ability to modify a digital image from its initial state. Often, a user wishes to modify the color properties of the entire image, or more commonly a selection of the image. For example, a user may wish to increase the saturation in a selection to make the colors more striking, and thereby make the selection stand out more in the image. Other color properties that the user may wish to change include chromaticity, lightness, and so on. Modification of the color properties of the selection will be referred to as color correction. [0003] In order to modify a selection of an image, the user must first have tools for defining the selection he wishes to modify. Some prior art selection tools ...
