Title
(EN) Method of image background blur
(ZH) 一种图像背景虚化的方法
Abstract
(EN)
The invention discloses a method of image background blur. The method utilizes the approach of estimating the depth of the defocus to extract the focal area of the image, namely extracting the focused subject, and segments the focused subject and the background with the combination of super pixel division. Morphological binarization means is utilized to obtain the template of the focused subject area and the background area, the method blurs the background area, and the resulting image of the final background blur is obtained through overlaying the image of the focused subject area and the image of the background area. The method is capable of highlighting the effects of the focused subject area through blurring the background of the original image, and the whole process realizes to be automated and self-capable without human intervention.

本发明公开了一种图像背景虚化的方法,该方法将离焦深度估计的方法用于提取图像中的准焦区域即关注主体,结合超像素分割将关注主体与背景分割,并利用形态学二值化手段得到对焦主体区域模板和背景区域模板,对背景区域进行模糊,进一步将关注主体区域图与模糊背景区域图叠加得到最终背景虚化的结果图。可实现对原图像的背景进行虚化从而突出关注主体区域的效果,全过程可实现自动化与自能化,无需人工干预。
