Embodiment 1

[0075] This embodiment provides a processing method for enhancing skin color, which is used in a processing device for enhancing skin color. like figure 1 As shown, the processing method for enhancing skin color includes the following steps:

[0076] In step S11, the image information of the skin color area of ​​the human face in the image is obtained, the image information includes the first color vector of each pixel in the skin color area, and the first color vector includes the color difference value of the red component and the color difference value of the blue component.

[0077] In the image processing technology of human face skin color, it is necessary to perform different processing on the category and depth of the image color. Therefore, in the image processing of human face skin color, it is usually distinguished by chroma (ie hue saturation). In this embodiment, the acquired image information of the skin color area of ​​the human face includes a first color vec...

Embodiment 2

[0086] This embodiment provides a processing method for enhancing skin color, which is used in a processing device for enhancing skin color. like figure 2 As shown, the processing method for enhancing skin color includes the following steps:

[0087] Step S21: Obtain the image information of the skin color area of ​​the human face in the image, the image information includes the first color vector of each pixel in the skin color area, and the first color vector includes the color difference value of the red component and the color difference value of the blue component. It is the same as step S11 in Embodiment 1, and will not be repeated here.

[0088] Step S22 , calculating the center area of ​​the skin color in the skin color area according to the color difference value of the red component and the color difference value of the blue component.

[0089] In this embodiment, the pixel color difference value of each pixel in the skin color area within the face frame is counte...

Embodiment 3

[0131] This embodiment provides a processing method for enhancing skin color, which is used in a processing device for enhancing skin color. like image 3 As shown, the processing method for enhancing skin color includes the following steps:

[0132] Step S31: Obtain the image information of the skin color area of ​​the human face in the image, the image information includes the first color vector of each pixel in the skin color area, and the first color vector includes the color difference value of the red component and the color difference value of the blue component. It is the same as step S21 in Embodiment 2, and will not be repeated here.

[0133] Step S32 , according to the color difference value of the red component and the color difference value of the blue component, calculate the center area of ​​the skin color in the skin color area.

[0134] In this embodiment, the pixel color difference value of each pixel block in the skin color area within the face frame is co...

Abstract

The invention discloses a skin color enhancement processing method and device and an image processing device. The method comprises the following steps: obtaining image information of skin color region of a human face in an image, wherein the image information comprises a first color vector of each pixel point in the skin color region, the first color vector comprising a red component color difference value and a blue component color difference value; according to the red component color difference value and the blue component color difference value, calculating a skin color center region in the skin color region; according to the relation between each pixel point in the skin color region and the skin color center region, calculating offset amount of the first color vector of each pixel point in the skin color region; and carrying out skin color enhancement processing on the image according to the offset amount of the first color vector. Selection of the skin color center region in a dynamic skin color model is set, so that skin color selection of the skin color center region is based on the feeling of the human eye on color difference, and real skin color under the current situation is reflected truly; and the processing method has a better skin color enhancement effect, and has wide applicability.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a processing method and device for enhancing skin color, and an image processing device. Background technique [0002] In the field of image processing technology, especially in human image processing, skin color enhancement is a relatively important part. Skin color enhancement is a part of skin color beautification, but the main focus of skin color beautification is on the texture and texture of the skin, while skin color enhancement It focuses on fine-tuning the skin color so that the picture looks more in line with aesthetic needs. [0003] The current mainstream skin color enhancement is mainly composed of two steps: skin color detection and skin color transformation. Among them, the skin color detection method is generally based on a static skin color model. The so-called static skin color model means that before the image is input, which areas in the colo...
