Title:
ELECTRONIC APPARATUS, VIRTUAL SAMPLE GENERATION METHOD AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/071663
Kind Code:
A1
Abstract:
Disclosed are an electronic apparatus, a virtual sample generation method and a storage medium. The method comprises: carrying out wavelet transformation processing on a first human face image, and acquiring a first wavelet coefficient of a low and medium frequency part in a grayscale value corresponding to the first human face image and a second wavelet coefficient of a medium and high frequency part in the grayscale value corresponding to the first human face image; carrying out wavelet transformation processing on an average human face image under a first illumination condition, and acquiring a third wavelet coefficient of a low and medium frequency part in a grayscale value corresponding to the average human face image and a fourth wavelet coefficient of a medium and high frequency part in the grayscale value corresponding to the average human face image; and replacing the first wavelet coefficient with the third wavelet coefficient, and carrying out wavelet inverse transformation processing on the third wavelet coefficient and the second wavelet coefficient so as to obtain a sample of the first human face image under the first illumination condition. By means of the method, the present invention solves the problem that the training sample collection process is tedious, saves a lot of manpower, and improves the efficiency of sample generation.
