Figure Lengend Snippet: (a) Pixel intensity distribution of Spectralon OCT images before (blue) and after (yellow) DW-SR (five 30 nm windows). The pixel intensity exhibits a Rayleigh distribution before DW-SR due to speckle noise, and shifted towards a Poisson distribution after DW-SR due to speckle reduction. (b) Normalized standard deviation C before and after DW-SR, plotted against a theoretical speckle reduction curve (dotted black line) if the speckle noise in the compounding images are completely uncorrelated
Article Snippet: A scattering Spectralon phantom (Labsphere, North Sutton, NH) was imaged to quantitatively demonstrate the capability of the DW-SR method in speckle reduction.
Techniques: Standard Deviation
