Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the present invention provides a method for interactive instant extraction of color information based on a mobile terminal, comprising the following steps:

[0016] Step 1, read image color data;

[0017] Step 2, the user inputs the number of color categories;

[0018] Step 3, select the initial cluster center;

[0019] Step 4, calculate the distance between the color of each pixel and each cluster center, and classify it into the category to which the nearest cluster center belongs;

[0020] Step 5, define the mean square error as the measurement function, and calculate the measurement function value of each type of color (Reference: Wang Jing. Research on Image Classification Algorithm Based on Color Features [D]. Dalian: Dalian Maritime University, 2012), if it does not converge , then calculate the RGB mean valu...

Abstract

The invention discloses a color information interactive instant extracting method based on a mobile terminal. The method comprises the following steps: step one, reading image color data; step two, inputting color category number by a user; step three, selecting an initial clustering center; step four, computing the distance between the color of each pixel and each clustering center, and classifying the distance into the category to which the nearest clustering center belongs; and step five, defining mean square error as a measure function, computing the measure function value of each categoryof color, and computing the RGB mean value of each category of color if the measure function value is not convergent, and updating the clustering center by taking the RGB mean value, and performing the next turn of clustering until the measure function convergence or cycle frequency exceeds the maximum set frequency.

Description

technical field [0001] The invention relates to an interactive instant extraction method of color information based on a mobile terminal. Background technique [0002] In product design and urban design, different color combinations can moderately connect nature with people and life. Designers often need to refer to the color structure in various images when color matching products or patterns. Some of the images come from the gallery or the Internet, while more reference images are captured by the designer based on his instant perception in life. Mobile terminals such as mobile phones now have a camera function, and it is very convenient to capture images, but there is still a lack of convenient tools for color extraction and application. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a mobile terminal-based interactive instant extraction method for color information, comprising the following steps: [000...
