CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. § 119 to Indian Patent Application No. 201941011541 (PS) filed on Mar. 25, 2019 and Indian Patent Application No. 201941011541 (CS), filed on Dec. 27, 2019, in the Indian Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety.

BACKGROUND

1. Field

The disclosure relates to image processing. More particularly, the disclosure relates to a method and an electronic device for processing facial images.

2. Description of Related Art

With the advance of technology, the electronic devices such as digital cameras, smart phones, notebooks, laptops, etc., are able to capture and process images to enhance appearance of objects. Faces of people are frequently captured by the image capturing devices, and face enhancement or beautification applications have huge popularity among users, who capture and post self-portrait images on social media.

SUMMARY

In accordance with an aspect of the disclosure, there is provided a method of generating a texture restored image by enhancing a source image. The method includes determining information associated with a source image. The information is indicative of at least one facial characteristic associated with at least one face in the source image. The method includes processing the source image using a filter based on the information associated with the source image. Further, the method includes performing wavelet decomposition on each of the filtered image and the source image. The method also includes determining weightage factors associated with the wavelet decomposition of each of the filtered image and the source image, based on the information associated with the source image. Further, the method includes obtaining a wavelet image to generate the texture restored image from the wavelet decomposition of each of the filtered image and the source image based on the weightage factors for processing the source image.
