1. A dark circle detection and evaluation method, comprising:
obtaining, by a processor, a to-be-processed image;
extracting, by the processor, a dark circle region of interest from the to-be-processed image;
performing, by the processor, color clustering on the dark circle region of interest to obtain n types of colors in the dark circle region of interest, wherein n is a positive integer;
determining, by the processor, a first color in the n types of colors as a dark circle color in the dark circle region of interest;
determining, by the processor, a second color in the n types of colors as a reference skin color in the dark circle region of interest;
determining, by the processor, a dark circle region in the dark circle region of interest based on the dark circle color and the reference skin color; and
obtaining, by the processor, a dark circle evaluation result based on the dark circle region.
