    2. Registration of SD-OCT en-face images with color fundus photographs based on local patch matching

      Registration of SD-OCT en-face images with color fundus  photographs based on local patch matching

      Registration of multi-modal retinal images is very significant to integrate information gained from different modalities for a reliable diagnosis of retinal diseases by ophthalmologists. However, accurate image registration is a challenging, we propose an algorithm for registration of summed-voxel projection images (SVPIs) with color fundus photographs (CFPs) based on local patch matching. SVPIs are evenly split into 16 local image blocks for extracting matching point pairs by searching local maximization of the similarity function. These matching point pairs are used for a coarse registration and then a search region of feature matching points is redefined for a more accurate registration ...

    3. Photonics innovations win R&D 100 Awards

      Photonics innovations win R&D 100 Awards

      Super-resolution microscopes from Carl Zeiss and Leica Microsystems, a novel radiation detector from Brookhaven National Lab (BNL), and an origami microscope are among more than a dozen optics and photonics innovations to win one of this year's R&D 100 Awards. Intended to recognize the 100 "most technologically significant products" introduced over the past year, the list also includes an all-fiber isolator from AdValue Photonics, an optical coherence tomography (OCT) diagnostic endoscope developed by NinePoint Medical, and a lunar laser communication system co-developed by NASA and MIT's Lincoln Laboratory.

    4. Automated mosaicing of feature-poor optical coherence tomography volumes with an integrated white light imaging system

      Automated mosaicing of feature-poor optical coherence tomography volumes with an integrated white light imaging system

      We demonstrate the first automated , volumetric mosaicing algorithm for optical coherence tomography (OCT) that both accommodates 6-DOF rigid transformations and implements a bundle adjustment step amenable to generating large fields of view with endoscopic and freehand imaging systems . Our mosaicing algorithm exploits the known, rigid connection between a combined white light and OCT imaging system to reduce the computational complexity of traditional volumetric mosaicing pipelines. Specifically, the search for 3D point correspondences is replaced by two, 2D processing steps: we first co-register a pair of white light images in 2D and then generate a surface map based on the volumetric ...

  2. About Stanford University

    Stanford University

    Stanford University was founded in 1891 by Leland and Jane Stanford to "promote the public welfare by exercising an influence on behalf of humanity and civilization." More than a century later, Stanford remains dedicated to finding solutions to the great challenges of the day and to preparing our students for leadership in today's complex world.
