Epiretinal Membrane Detection Bhavna Antony
Method • Detect ILM • Refine ILM surface detection • search for 2 surfaces i.e. ERM and ILM • Edge cost terms derived from 2-D edge detector because volumes have few slices. • Regional term looks for bright bounding surfaces and dark spaces. • Works well for clear subretinal spaces, fails in the case of pockets that have mueller cells.
Status of Flattening Paper Previously used two 3-D splines Now using one 3-D spline, followed by 2-D spline estimating “ripple” in y-direction
After 3-D spline fit and flattening After 2-D spline fit and flattening
Use dual direction scans to estimate artifact free OCT volume Horizontal Scan 128 Vertical Scan 128
