Abstract

The invention belongs to the technical field of image processing, and particularly relates to a method for extracting primary colors of a painting work image. The method comprises the following steps: 1, color clustering, to be specific, inputting the painting work image, and selecting 15 colors; 2, factor quantification, to be specific, analyzing area factors, purity factors and comparison factors of the 15 colors; 3, color sequencing, to be specific, grading the three types of factors in the step 2 to obtain grades of the 15 colors; 4, color selection, to be specific, selecting 5 colors according to the grade sequence and the selection rule in the step 3. The method disclosed by the invention has the benefits that the primary accurate colors of the painting work image can be obtained, so that the primary colors instruct image coloring and image color transmission to achieve a better effect. By the adoption of the method, a painting process of a person is fully considered, and quantification is realized, so that the primary colors of the painting work image conforming to human visual cognition are obtained. The method is qualitatively improved in the result quality aspect.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a main color extraction method of a painting image. Background technique [0002] Color combinations are often used in art to describe the main colors of an image, that is, the main color composition of an image. Color combination (color theme or color combination) is a group of collocations composed of several colors, commonly used three-color combination and five-color combination. [0003] In the international related research work on the extraction of the main color of the image, the simplest method is the extraction method based on the color histogram, that is, the three or five colors with the largest number of pixels in the color histogram are selected as the main colors. After that, a main color extraction method based on block is proposed, which considers the spatial position distribution of image color, divides the image into regular rectangular bl...
