Embodiment 1

[0020] See figure 1 , which shows the implementation flowchart of the method for obtaining the oily area in the face image provided by the present application. The method for obtaining the oily area in the face image provided by the present application can be applied to various smart terminals, for example, the smart terminal It can include various electronic devices that can take pictures, such as mobile phones, cameras, computers, and tablet computers.

[0021] like figure 1 As shown, the method for obtaining the oily area in the face image includes the following steps:

[0022] S101. Acquire a first image including a human face.

[0023] Wherein, the first image is an original image, that is, an original image obtained by taking pictures with a camera. Certainly, the first image may also be a processed image, and the image includes a greasy face area.

[0024] S102. Perform blurring processing on the first image to obtain a second image.

[0025] Wherein, performing bl...

Embodiment 2

[0072] Based on the same idea as that of Embodiment 1, correspondingly, this embodiment also provides a device for acquiring oily areas in a face image.

[0073] See Figure 5 , which shows a schematic structural diagram of the device for obtaining the oily area in the face image provided according to the present application, as shown in Figure 5 As shown, the device 500 includes: an image acquisition module 510, which is used to acquire a first image containing a human face; a blur processing module 520, which is used to perform blur processing on the first image to obtain a second image; a skin color area recognition module 530, It is used to identify the skin color area of ​​the human face in the first image based on the pixel parameters of the first image and the second image under the RGB color model; the highlight area identification module 540 is used to obtain the highlight in the skin color area area, and confirm that the highlight area is the target oily area in th...

Abstract

The invention belongs to the technical field of image processing, and specifically discloses a method and a device for acquiring an oily region in a face image. The method comprises the following steps of: carrying out fuzzy processing on the obtained first image containing a human face to obtain a second image which is blurred, and identifying a skin color region of the human face in the first image based on pixel parameters of the first image and the second image under an RGB color model; and secondly, calculating and acquiring a highlight region in the skin color region, and determining that the highlight region is the target oily region in the first image. According to the method, the oily region in the portrait image is effectively identified, the highlight region in the background cannot be mistakenly recognized as the oily region, the implementation process of the method is simple, complex calculation is not needed, and the method has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method and a device for acquiring oily areas in human face images. Background technique [0002] When taking portrait photos, due to lighting and other reasons, it is easy to produce obvious oily sheen, making the people in the photos look old, with dirty and greasy faces. Therefore, when taking general wedding photos, parent-child photos, etc., some methods will be used to remove oily shine in post-image processing. Most of this method of removing oily light can only be used for partial post-processing, which requires the use of relatively large computing resources, so the application scenarios are very limited, and professional personnel are required to operate. Contents of the invention [0003] The present application provides a method and device for acquiring oily areas in human face images, which are used to solve the problem of effective identific...
