Mumford–Shah algorithm applied to videokeratography image processing and consequences to refractive power values

Corneal topography reinterpretation through separate analysis of the projected rings

“…This work, like others1,[3][4][5] , improves videokeratography algorithms by using open methods. The ESA allows an analysis of annular regions of the surface, fact that reduces the unequal density of samples in different sectors of the surface and improves the fitting.…”
