Problems solved by technology

However, on the one hand, with the continuous improvement of the hardware of smart devices, the pixels of the cameras are also continuously improved, and the images taken are getting larger and larger, which is quite time-consuming for the existing algorithms for the blurring and skinning processing of these full images. On the other hand, the information of image details (such as eyes, eyebrows and nose, etc.) will be lost after the full image is blurred, which will cause the processed image to become unclear and make the face look not very energetic

Embodiment 1

[0052] figure 1 It is a flow chart of a beautifying treatment method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of performing beautifying treatment on portraits in pictures. This method can be integrated into a smart phone or a digital The beautification processing device in the camera equipment is implemented, specifically including the following steps:

[0053] Step 110, perform face detection on the picture to be processed, and determine the face area in the picture to be processed.

[0054] Wherein, the picture to be processed can be a local picture or a picture collected in real time by a camera, face detection is performed on the picture to be processed, and if no face is detected in the picture to be processed, return to continue to obtain the picture to be processed. Preferably, face detection is performed on the picture to be processed through an open source computer vision library, and the face area in the pictu...

Embodiment 2

[0066] image 3 It is a flow chart of a beauty treatment method provided for an embodiment of the present invention. On the basis of the above technical solution, preferably, step 120 includes:

[0067] Step 121. Obtain key points of the estimated human face.

[0068] Specifically, for example, the estimated face key points may be obtained according to a face picture dataset marked with human face key points. The face picture data set includes at least 20,000 human face pictures that have manually marked the key points of the face. The key point location of the face can be understood as, assuming that the real key point position of the face is S'=(x 1 ,y 1 ,...,x n ,y n ), where (x 1 ,y 1 ) is the coordinates of the first face key point in the picture, (x n ,y n ) is the coordinates of the nth face key point in the picture, the process of predicting the face key point position S can be converted into an optimization problem: min||S-S'||, even if the predicted face key ...

Embodiment 3

[0080] Figure 8 It is a flow chart of a beauty treatment method provided for an embodiment of the present invention. On the basis of the above technical solution, it is further refined. Step 150 includes:

[0081] Step 151. Acquire the area to be processed in the image to be processed.

[0082] Among them, the area covered by the beautification processing layer in the image to be processed is determined as the area to be processed, the beautification processing of the image to be processed is to perform beautification processing on the area to be processed, and the area outside the area to be processed in the image to be processed is not beautified. Yan treatment.

[0083] Step 152: Perform beauty treatment on areas other than the set area in the area to be processed, and generate a pre-processed picture.

[0084] Among them, the face key point layer and the skin color processing layer synthesize the beautification processing layer, and the setting area in the face key point ...

Abstract

The present invention discloses a beauty processing method and device. The method comprises: performing face detection of a picture to be processed, and determining the face area in the picture to be processed; performing face key point detection of the face area, determining the face key points, and generating a face key point layer according to the face key points; detecting the skin color area of the picture to be processed, and generating a skin color processing layer; splicing at least one setting area in the face key point layer to a position synthesis beauty processing layer corresponding to the skin color processing layer; and performing beauty processing of the picture to be processed according to the beauty processing layer, and generating a beauty picture. The beauty processing method and device are able to realize the beauty process of a portrait in a picture and reserve the details of a face setting area.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to a method and device for beautification processing. Background technique [0002] With the rapid development of digital technology in recent years, people record every detail of life through devices with camera functions. Therefore, there are more and more image editing software to improve the effect of taking pictures. The most demanded one is face editing for selfies. [0003] However, existing beautification solutions generally perform overall blurring and tone adjustment on the entire picture to achieve visual whitening and skin resurfacing effects. However, on the one hand, with the continuous improvement of the hardware of smart devices, the pixels of the cameras are also continuously improved, and the images taken are getting larger and larger, which is quite time-consuming for the existing algorithms for the blurring and skinning processing of the...
