Global Teleophthalmology With the Smartphone for Microscopic Ocular Surgery.

Eye Contact Lens

September 2016

Department of Ophthalmology (Y.Y., J.Z., X.H., H.Z.), Hangzhou First People's Hospital, Hangzhou, China; Bascom Palmer Eye Institute (J.W., H.J.), University of Miami, Miami, FL; and Hangzhou Normal University (Y.X.), Medical College, Hangzhou, China.

Purpose: This study aimed to determine the feasibility and quality of real-time video transferring in global teleophthalmology using two smartphones during microscopic ocular surgery.

Methods: An iPhone 4S (Apple) was adapted into a surgical microscope in Hangzhou, Zhejiang, China to capture video during microscopic ocular surgery. An iPhone 5 (Apple), an iPad2 (Apple), and a desktop computer were used as the receptor on the other side of the globe (Miami, FL).

Hard and soft classification techniques are the conventional methods of image classification for satellite data, but they have their own advantages and drawbacks. In order to obtain accurate classification results, we took advantages of both traditional hard classification methods (HCM) and soft classification models (SCM), and developed a new method called the hard and soft classification model (HSCM) based on adaptive threshold calculation. The authors tested the new method in land cover mapping applications.
