|1. (WO2018176929) IMAGE BACKGROUND BLURRING METHOD AND APPARATUS|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||IMAGE BACKGROUND BLURRING METHOD AND APPARATUS|
Embodiments of the present application disclose an image background blurring method and apparatus. The method comprises: extracting a reference image and m non-reference images from a target video according to an image extraction rule; constructing a first image pyramid by using the reference image, and constructing m second image pyramids by using the m non-reference images; determining a scene depth map of the reference image by using the first image pyramid and the m second image pyramids; dividing pixel points of the reference image into n depth layers by using the scene depth map; determining target positions in the reference image; determining, from the n depth layers, a target depth layer at which pixel points corresponding to the target positions are located; and blurring pixels to be processed. In the embodiments of the present application, pixels to be processed comprised in a depth layer of n depth layers other than a target depth layer can be blurred, so as to obtain an image in which pixels of the target depth layer are clear and the pixels to be processed are blurred.
