Embodiment Construction

[0058] Embodiments of the present invention provide an image processing method and device, which can improve the efficiency and accuracy of human face capture.

[0059] see figure 1 , an embodiment of the image processing method in the embodiment of the present invention includes:

[0060] 101. Perform wavelet transform processing on the collected face image to determine the position of the human eye;

[0061] In this embodiment, after the human face image is collected, wavelet transform processing may be performed on the collected human face image to determine the position of the human eyes.

[0062] 102. Select the front face image according to the determined human eye position;

[0063] Since the human eyes are located in the front of the human face, after the human eye positions are determined, the front face image can be selected according to the determined human eye positions.

[0064]103. Perform pixel point difference processing on the frontal face image to determin...

Abstract

The embodiment of the invention discloses an image processing method and a device. The method comprises the following steps: collected facial images are subjected to wavelet transform to define positions of human eyes; choosing front-view facial images according to the positions of the human eyes; the front-view facial images are subjected to pixel point differential processing to define a target facial image satisfying preset conditions. The embodiment of the invention also provides an image processing device. The method and the device can improve the efficiency and precision of face capture.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing method and device. Background technique [0002] In recent years, with the advancement of national strategic projects such as "Smart City" and "Safe City", the demand for capturing and analyzing the faces of people entering and exiting at the entrances and exits of urban villages, smart communities, commercial buildings, and industrial and mining enterprises will increase. More and more, with the rapid development of computer hardware and the gradual maturity of face recognition algorithms, the application of face recognition is becoming more and more extensive. [0003] Face capture is an important part of face recognition. In the existing technology, after the data image is collected, the face capture is often performed manually by technicians. The technician will select the face with the naked eye, and then the computer will perform the face capture....
