The Perfect Picture: Optimising Chromostereoscopic Images for Desired Depth and Colour

Abstract

Chromostereoscopic images encode depth as colour, with the red part of the visible spectrum encoding nearby depths and the blue part encoding far-away depths. However, when encoding a regular image with its depth, the generated colours may not match with the original colours in the image. Following a user study, a technique has been developed which takes both the chromostereoscopic effect and the original colours into consideration.

This problem was solved by creating a program to generate chromostereoscopic images from an arbitrary RGBD input image. An optimisation metric was devised to assess if a chromostereoscopic image takes both the target depth and original image into consideration. A user study was conducted to correct this metric with respect to human perception. The new technique can take a desired amount of original colour and chromostereoscopic depth and will generate a chromostereoscopic image, taking these preferences into account.
