Patent attributes
Disclosed herein are embodiments of systems and computer-implemented methods for extracting a set of discrete colors from an input image. A playful palette may be automatically generated from the set of discrete colors, where the playful palette contains a gamut limited to a blend of the set of discrete colors. A representation of the playful palette may be displayed on a graphical user interface of an electronic device. In a first method, an optimization may be performed using a bidirectional objective function comparing the color gamut of the input image and rendering of a candidate playful palette. Initial blobs may be generated by clustering. In a second method, color subsampling may be performed from the image, and a self-organizing map (SOM) may be generated. Clustering the SOM colors may be performed, and each pixel of the SOM may be replaced with an average color value to generate a cluster map.
