Providing diverse and representative swatches extracted from an input image

A non-transitory computer-readable medium embodying program code for determining a set of representative swatches of an image, the program code comprising instructions which, when executed by a processor, cause the processor to perform operations comprising:

• determining a salient object in an image, where the salient object includes pixels that depict a pattern or color visible on the salient object;
• extracting multiple swatches from the image, wherein each of the multiple swatches includes pixels that depict the pattern or color visible on the salient object;
• computing selection scores for the multiple swatches, respectively, wherein, for each particular swatch of the multiple swatches, a respective selection score is computed by:
• determining, for the particular swatch, (i) a respective likelihood score indicating a representativeness of the pattern or color depicted by the pixels included in the particular swatch, and (ii) a respective dominance value indicating a dominance of the pattern or color depicted by the pixels included in the particular swatch, and
• determining, for the particular swatch, a respective selection score based on a combination of the respective likelihood score and the respective dominance value;
• and
• generating, based on the selection scores of the multiple swatches, a subset of the multiple swatches extracted from the image.

A system for determining a set of representative swatches of an image, the system comprising:

• a means for determining a salient object in an image, where the salient object includes pixels that depict a pattern or color visible on the salient object;
• a means for extracting multiple swatches from the image, wherein each of the multiple swatches includes pixels that depict the pattern or color visible on the salient object;
• a means for computing selection scores for the multiple swatches, respectively, wherein, for each particular swatch of the multiple swatches, a respective selection score is computed by:
• determining, for the particular swatch, (i) a respective likelihood score indicating a representativeness of the pattern or color depicted by the pixels included in the particular swatch, and (ii) a respective dominance value indicating a dominance of the pattern or color depicted by the pixels included in the particular swatch, and
• determining, for the particular swatch, a respective selection score based on a combination of the respective likelihood score and the respective dominance value;
• and
• a means for generating, based on the selection scores of the multiple swatches, a subset of the multiple swatches extracted from the image.
