color space, such as XY Z, is an important step in the camera processing pipeline. Until now,
this procedure has been primarily solved by using a 3× 3 matrix obtained via a least-squares
optimization. In this paper, we propose to use the spherical sampling method, recently
published by Finlayson et al., to perform a perceptual color characterization. In particular, we
search for the 3× 3 matrix that minimizes three different perceptual errors, one pixel based …
