Human color discrimination for memory-efficient encoding in extended reality

A method for memory-efficient encoding in an extended-reality device, the method comprising:

• calculating a plurality of two-dimensional boundaries in a color space;
• ascertaining extrema points for two or more two-dimensional boundaries of the plurality of two-dimensional boundaries;
• adjusting a color value within at least one of the two-dimensional boundaries to generate an adjusted color that reduces variances of color values for a color channel, based on ascertaining the extrema points for the two or more two-dimensional boundaries;
• and
• presenting the adjusted color on a display.

A memory device comprising instructions that, when executed by one or more processors, cause the one or more processors to perform the following steps:

• calculating a plurality of two-dimensional boundaries in a color space;
• ascertaining extrema points for two or more two-dimensional boundaries of the plurality of two-dimensional boundaries;
• adjusting a color value within at least one of the two-dimensional boundaries to generate an adjusted color that reduces variances of color values for a color channel, based on ascertaining extrema points for the two or more two-dimensional boundaries;
• and
• presenting the adjusted color on a display.
