摘要

There is provided a system and method for color representation generation. In an aspect, the method includes: receiving three base colors; receiving a patchwork parameter; and generating a color representation having each of the three base colors at a vertex of a triangular face, the triangular face having a color distribution therein, the color distribution discretized into discrete portions, the amount of discretization based on the patchwork parameter, each discrete portion having an interpolated color determined to be a combination of the base colors at respective coordinates of such discrete portion. In further aspects, one or more color representations are generated based on an input image and can be used to modify colors of a reconstructed image.

說明書

In some cases, the layout of the color sail on the user's screen does not have to be fixed; i.e., the user can deform the triangle in any way for easier exploration and color picking. Additionally, it is contemplated that the color sail can have any suitable shape; for example having rounded sides. In further cases, other types of arrangements for the sail colors can be used; for example, as shown in FIG. 21.

Advantageously, the color sail has a fixed number of parameters, unlike other approaches to interactive continuous gamuts, making it more amenable to machine learning approaches. As well, the discrete-continuous setting gives color sail an additional degree of flexibility, varying the number of represented colors with no change to the required storage.
