Embodiment Construction

[0022] The method disclosed in the present invention can be applied to electronic devices with image processing capabilities, such as personal computers, digital cameras, digital photo frames and other electronic devices. However, it should be noted that the method of the present invention is not limited to the above examples, and is only described here. And in order to clearly illustrate the technical means of the present invention, the following terms are defined here.

[0023] The input image P is an image of the size of an x*y pixel array; the selection window is an m*n pixel array, where m and n are positive integers, and in the implementation of the present invention, the selection window of 5*5 is For example, which is not a limitation of the present invention, please refer to Table 1 for the arrangement of pixels in the selected window, and Pn is the nth position in the selected window; in this implementation description, P12 is used as the target pixel.

Abstract

The invention discloses a method for beautifying faces in a digital image, which carries out beautifying processing on a facial region of an input image. The method comprises the following steps: setting a selection window for selecting part image regions of the input image; assigning a target pixel from the selection window and assigning the rest of pixels as comparison pixels; performing a detail test program according to a variation amount of the target pixel to the comparison pixels and judging whether the target pixel has detailed information or not; performing a brightness test program on the target pixel and judging whether the target pixel corresponds to a brightness region or not; performing a nonlinearity filtering program, processing the target pixel by a nonlinearity filter togenerate a filter value, providing a mixing proportion and mixing the target pixel and the filter value in the mixing proportion to generate a completed pixel; replacing the original target pixel with the completed pixel; and repeating the steps until all the pixels are completed.

Description

technical field [0001] The invention relates to a digital image processing method, in particular to a face beautification method in a digital image. Background technique [0002] With the development of digital cameras, photography is no longer an expensive consumption. Users can take desired images at will to record memorable moments or scenes. Especially shooting people is one of the key points of many photographers. However, during the shooting process, the subject may be affected by factors such as spots, dust or fine lines on the face, which will affect the reader's perception of the captured digital image. [0003] In order to solve this problem, although digital image editing software can be utilized to edit the digital image in detail. However, not all users are familiar with image editing software, which also raises the entry threshold for users. Another way is to increase the softening of the image, although it can partially dilute the above-mentioned color blo...
