Also, the speed in performing the processes of area computing and damage evaluation, especially in the extensive damaged forest regions is very slow; consequently, the expression of results takes more ti...
A two stage approach for burnt scar detection from single date multispectral medium spatial resolution optical remote sensing data (AWIFS) has been developed. The approach includes first an identification of burnt scar seeds based on a learning algorithm followed by a region growing process. An Artificial Neural Network (ANN) and a Classification tree (CT) were tested as learning algorithms. Bo...
Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
