Development and evaluation of a head-mounted display system based on stereoscopic images and depth algorithms for patients with visual impairment.

Abstract: In this work, we developed a wearable system using a commercial stereoscopic head-mounted display. We compared depth first-then contour (df-tc) and contour first-then depth (cf-td) algorithms in terms of images processed per second rate versus the window size and sweep values. Likewise, we...
