On the illumination compensation of retinal images by means of the bidimensional empirical mode decomposition
(SPIE, 2015)
Retinal images are used for diagnostic purposes by ophthalmologists. However, despite controlled conditions in acquisition retinal images often suffer from non-uniform illumination which hinder their clinical use. In this ...
Programmable diffractive optical elements for extending the depth of focus in ophthalmic optics
(SPIE, 2015)
The depth of focus (DOF) defines the axial range of high lateral resolution in the image space for object position. Optical devices with a traditional lens system typically have a limited DOF. However, there are applications ...
Improving the blind restoration of retinal images by means of point-spread-function estimation assessment
(SPIE, 2015)
Retinal images often suffer from blurring which hinders disease diagnosis and progression assessment. The restoration of the images is carried out by means of blind deconvolution, but the success of the restoration depends ...
