[POSTER] Optimizing Background Subtraction for OST-HMD

Color Contrast Enhanced Rendering for Optical See-Through Head-Mounted Displays

“…Thereafter, the background color is subtracted from the rendered color of the virtual scene [5]. Certain research pays more attention to colorimetric estimation [8], [25] or radiometric measurement [7] of the background to obtain background information with higher accuracy.…”

“…These approaches attempt to mitigate the color-blending effect via the subtraction compensation. Researchers have developed high-precision, pixel-precise color correction algorithms [6], [7] and accurate colorimetric background estimation [8]. However, for commercial OST-HMDs, such as Google Glass 1 , Microsoft HoloLens 2 , and Magic Leap 3 , using the subtraction compensation may decrease the brightness of the virtual content, resulting in low visual distinctions between rendered images and the physical environment.…”
