Abstract:
1. An object based boundary refinement method for object segmentation in digital images comprising the steps of: a) Inputting an image; b) Inputting a single initial object regions of interest; Using a computer to perform the steps of c) Performing refinement zone definition using the initial object regions of interest to generate refinement zones output, wherein the refinement zones output consists of an outer-limit zone and an inner-limit zone; d) Performing directional edge enhancement using the input image and the refinement zones to generate directional enhanced region of interest output; e) Performing radial detection using the input image, the refinement zones and the directional enhanced region of interest to generate radial detection mask output; f) Performing final shaping using the radial detection mask to generate single object region output wherein the final shaping step further consists of the steps of:
