Techniques are disclosed for selecting a targeted portion of a digital image. In one embodiment, a selection cursor having central and peripheral regions is provided. The central region is used to force a selection or a deselection, and therefore moving the central region over a portion of the image causes that portion of the image to be selected or deselected, respectively. The peripheral region of the cursor surrounds the central region and defines an area where a localized level set algorithm for boundary detection is performed. This provides more accurate boundary detection within the narrowly-focused peripheral region and eliminates the need to apply the level set algorithm across the entire image. Thus moving the peripheral region of the selection cursor over a boundary of the targeted portion of the image applies the level set algorithm in that boundary region and increases the likelihood that the boundary will be detected accurately.
A method for defining a selection region in a source image, the method comprising:
An image segmentation system that includes a memory device and a processor that is operatively coupled to the memory device, wherein the processor is configured to execute instructions stored in the memory device that, when executed, cause the processor to carry out an image segmentation process, the process comprising:
A non-transitory computer readable medium having instructions encoded thereon that, when executed by one or more processors, causes an image segmentation process to be carried out, the process comprising:
