Application of cepstral preprocessing for the improvement of spatial contrast of ocular fundus images

A method based on the cepstral analysis is proposed to preprocess fundus images. The method effectively reveals spectral peaks in a narrow band of spatial frequencies thus improving the spatial contrast of the image. The resulting images can be readily used for an automated structural analysis of ey...

Description
Summary:A method based on the cepstral analysis is proposed to preprocess fundus images. The method effectively reveals spectral peaks in a narrow band of spatial frequencies thus improving the spatial contrast of the image. The resulting images can be readily used for an automated structural analysis of eye pathologies. The method is applied to stitch several small-aperture fragments together.[PUBLICATION ABSTRACT]
