      Direct Estimation of Choroidal Thickness in Optical Coherence Tomography Images with Convolutional Neural Networks
      Automatic and accurate estimation of choroidal thickness plays a very important role in a computer-aided system for eye diseases. One of the most common methods for automatic estimation of choroidal thickness is segmentation-based methods, in which the boundaries of the choroid are first detected from optical coherence tomography (OCT) images. The choroidal thickness is then computed based on the detected boundaries. A shortcoming in the segmentation-based methods is that the ...

  2. About The Chinese University of Hong Kong

    The Chinese University of Hong Kong

    The Chinese University of Hong Kong, commonly referred to as CUHK, is the second oldest university in Hong Kong; it is campus-based and also the only collegiate university in the territory. Despite its name, the Chinese University does not conduct its classes solely in Chinese. Both Chinese (Mandarin and Cantonese) and English are languages of instruction.

    The university's founders hoped that it would become the bridge that connects China and the West, and to combine tradition with modernity. The collegiate system CUHK comprises four colleges: Chung Chi College, New Asia College, United College, and Shaw College. All undergraduates are affiliated to one of them. Currently, five new colleges are to be established in the near future; namely Morningside College, S. H. Ho College, C. W. Chu College, Wu Yee Sun College and Lee Woo Sing College.

    Founded in 1963, The Chinese University of Hong Kong (CUHK) is a forward looking comprehensive research university with a global vision and a mission to combine tradition with modernity, and to bring together China and the West. CUHK teachers and students hail from all corners of the world. In 2007, we have more than 5,800 staff members, some 20,000 undergraduate and postgraduate students. Of these students, about 3,000 are from 45 countries and regions outside Hong Kong. The 100,000 alumni are connected through some 80 alumni associations both within and outside Hong Kong.
