Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0047] The embodiment of the present invention provides a face detection method, see figure 1 , the method includes:

[0048] S1. Obtaining a face image;

[0049] S2. Perform blurring processing on the face image to compress the data volume of the face image;

[0050] S3. Detecting a human face from the processed image.

[0051] It should be noted that when the human eye recognizes a face, it can correctly judge a face using only a small amount of fuzzy overall features. It does not require these features to be detailed at the pixel level, nor does it require information about all pixels. This implementation Example After obtaining the face image, blur the face image without changing the size of the face image, such as figure 2 Th...

Abstract

The invention discloses a face detection method. The method comprises the following steps: acquiring a face image; performing fuzzy processing on the face image to compress the data volume of the faceimage; and detecting a human face from the processed image. In addition, the invention discloses a face detection system. According to the invention, the face detection rate can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a face detection method and system. Background technique [0002] At present, face detection and recognition algorithms are mostly at the image pixel level, using all pixel values ​​to extract detailed face features, but inspired by the working mode of human eyes, this processing method is not the mechanism for human eyes to recognize faces. When the human eye recognizes a face, it can make a correct judgment using only a small amount of fuzzy overall features. It does not need these features to be detailed at the pixel level, nor does it need information about all pixels. Even if the picture is fuzzy information, the human eye can quickly judge that it is a human face as a whole, which proves that the facial features extracted from the pixel level have redundant information for the recognition ability of the human eye. Therefore, the current algorithm for face detectio...
