Abstract

The invention provides an image segmentation method and a mobile terminal and relates to the electronic technology field. A problem that an existing intelligent mobile phone of a single camera can not well segment a portrait is solved. The method comprises the following steps of acquiring an image to be segmented including the portrait and a portrait shape image which is generated in advance; according to the image to be segmented, adjusting the portrait shape image and acquiring the portrait shape image matching with the image to be segmented; and according to the portrait shape image, segmenting the portrait and a background in the image to be segmented and acquiring the segmented image. In the scheme of the invention, a single image is taken as input, the segmented image in which the portrait and the background are accurately segmented is acquired and an application of the portrait segmentation of the single camera is realized. Through the portrait shape image, segmentation is guided so that segmentation precision and accuracy are increased.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to an image segmentation method and a mobile terminal. Background technique [0002] With the continuous popularization of smart phones and the better and better imaging quality of the shooting equipment equipped with smart phones, it has become an indispensable high-frequency habit in daily life for users to take pictures with mobile phones. Among all the shooting scenes, shooting portraits is undoubtedly one of the most important scenes, especially selfies of portraits. Nowadays, selfie-based applications are becoming more and more popular, such as beauty, background blur, etc. [0003] Background blur is a technology that simulates the shallow depth domain of a SLR, and has the shocking effect of highlighting the center of gravity (such as a person) in a shot. The more popular method now is to use a device based on dual cameras to calculate the depth map th...
