Embodiment Construction
[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0027] Automatic white balance can solve a series of problems of image color reproduction and tone processing. Ordinary cameras can automatically detect the color temperature value of the object to be photographed according to the light conditions of the lens and white balance detector, and select the closest color tone setting. However, the image auto white balance is less effective when shooting in low light conditions. This sol...

The invention discloses a method for generating an automatic white balance model. wherein the automatic white balance model is suitable for outputting color correction values of images, comprises a first convolution processing layer, a second convolution processing layer and a full connection layer, and comprises the following steps: collecting original images under different light source environments, and marking a target color value of each image, and the original images comprise a face image and a non-face image; Preprocessing the original image to extract feature information of the image;Based on the feature information of the non-face image, inputting the marked non-face image into a first convolution processing layer and a full connection layer for training; And based on the featureinformation of the face image, inputting the marked face image into a second convolution processing layer for training to generate a trained automatic white balance model. According to the scheme, the automatic white balance processing efficiency and precision of the image can be improved, and the skin color can be adjusted to an ideal value range according to different light source environments.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method for generating an automatic white balance model, an image processing method, a computing device and a storage medium. Background technique [0002] With the development of mobile phone chips, more and more functions can be realized on the mobile phone platform, especially the functions of the built-in camera of the mobile phone are becoming more and more rich and specialized. At present, more and more mobile phone manufacturers focus on the Selfie function. The automatic white balance function of mobile phone cameras will come with automatic facial white balance. However, the current automatic facial white balance function generally locks the skin color. Skin color correction at fixed value. However, since the target value of skin color correction under different light sources is not fixed, this method of adjusting skin color cannot achieve the optimal effect. ...
