kr.yhat

Kernel regression on sphere using Fisherian density with
polar coordinates

Reconstructs retinae by morphing a flat surface with cuts
(a dissected flat-mount retina) onto a curvilinear surface (the
standard retinal shape). It can estimate the position of a point
on the intact adult retina to within 8 degrees of arc (3.6% of
nasotemporal axis). The coordinates in reconstructed retinae can
be transformed to visuotopic coordinates. For more details see
