Microsoft delivers visual quality improvements to the Windows Mixed Reality VR platform


Microsoft worked with HP and Valve for the development of HP Reverb G2 VR headset. During this development, Microsoft made some visual quality improvements to the Windows Mixed Reality VR platform. In addition to the HP Reverb G2 VR headset, these improvements are available for all the existing Windows Mixed Reality VR headsets as well. Read about the new improvements below.

Chromatic Aberration Correction:

Chromatic aberration is an artifact caused by red, green, and blue light refracting through lenses differently. A white pixel on the panels will refract through the lenses and separate into red, green, and blue pixels visible to the viewer. Chromatic aberration correction aims to adjust for this by pre-distorting the rendered image so that the image viewed by the user after lens refraction appears as a single white pixel as intended. Chromatic aberration artifacts usually look like opposing red and blue color fringes emanating from the center of the optics

Microsoft has delivered new improved algorithms to several Windows Mixed Reality headsets to improve the visual quality. Check out the below image to see the difference.

Light Leak Correction:

Almost every VR headset released to date has had some level of visual corrections implemented in software or on the GPU to correct for artifacts caused by some aspect of the hardware. Correcting for lens distortion is a great example of this.

Microsoft’s correction algorithms reduce both color fringing and the overall color tinting. Check out the below image to see the difference.
