Contrast sensitivity function (Barten's model)

Calculate contrast sensitivity values of input spatial frequencies using the Barten's model

Calculate contrast sensitivity values of input spatial frequencies using the Barten's model. Input parameters include spatial frequency (cycle/degree), display luminance (cd/m2), surrounding luminance (cd/m2), and field of view (degree).
