Abstract

The invention belongs to the field of digital image processing and discloses a method for automatically removing image black eyes. The method is characterized by comprising the following steps: first drawing the contour regions of a left eye bag and a right eye bag and marking as eye bag contour pictures; then, obtaining a face region picture; extracting the brightness of each pixel of the face region, leading into a result and marking as an image B; sequentially carrying out average filtering, high contrast reservation and brightening algorithms on the image B to obtain an image C; sequentially carrying out average filtering and histogram statistics on the image B, then calculating the image B with the eye bag contour pictures and the image C to obtain an image D, and carrying out Gaussian blurring on the image D; carrying out Gaussian blurring on the face region to obtain a face Gaussian picture; finally calculating the image D, the face region and the face Gaussian picture to obtain a result picture. The technical scheme realizes the function of automatically removing black eyes, reduces user operation difficulty and threshold to the lowest, can be popularized in various portable digital devices, saves man-machine interaction devices such as a mouse and a keyboard, is low in hardware cost and has the characteristics of convenience and rapidness.

Description

technical field

[0001] The invention relates to a digital image processing method. Background technique

[0002] The widespread use of portable digital devices has made photography an operational skill with a lower threshold, so that people can record their own activities at any time for home, business and other fields. Portrait shooting is one of the usual technical means. This kind of portraits captured by digital equipment has better editing capabilities. For aesthetic considerations, dark circles in portraits often require technical processing, but usually digital images can be used for such delicate processing methods Processing software for editing, but its technical requirements are very high, and the operation steps are numerous, time-consuming, and even professional human-computer interaction tools such as mouse, stylus, etc. are required. Therefore, this method is difficult to popularize on popular portable digital devices , causing many users to be helpless with...
