Figure 4

This shows how we obtained our valid region for the Orange County Coastline example. Figure (a) is the initial aerial image of the region to be considered. The region of interest is about 15.2 km by 10 km. Figure (b) is the denoised version of the initial image. We took this denoised image and smoothed away from regions of large discontinuities to obtain figure (c)., (a) Google earth image of orange county coastline, (b)Orange county coastline denoised image, (c)Orange county coastline smoothed image
