Method and system for scratching target object from digital picture

Abstract

The invention discloses a method for scratching a target object from a digital picture, which belongs to the technical field of the image processing and the human-computer interaction. The method comprises the following steps that: a plurality of nodes are arranged on the boundary of a target object through a human-computer interaction device, a straight line or a curved line is arranged between nodes, and the lines are enclosed to form a boundary outline of the target object; any target point on the node or on the nodal interval line is pressed through the human-computer interaction device, and different operations are respectively executed by judging whether the target point after being pressed is dragged within a given time, and the operations comprise: directly changing the straight or curved shape of the line, changing the nodal position and adjusting the shape of the line which is connected with the nodes, inserting new node, and deleting existed node. With the method and the system, target object can be simply, conveniently, correctly and directly scratched from the digital picture image on a plurality of electronic devices.

Description

technical field [0001] The invention relates to the technical field of image processing and human-computer interaction, in particular, using a computer mouse, or a touch screen of an electronic device such as a mobile phone or an IPad as a human-computer interaction device, for certain objects of interest in a digital picture, such as a person or a certain part of a person After the boundary contours of the area where some specific parts (such as the head) are located are determined, only the object of interest in the picture is kept and the rest is cleared. Background technique [0002] People have a large number of digital pictures containing objects of interest in their daily life. Objects of interest may be people, parts of people, animals, flowers, etc. For the convenience of description, the following sections collectively refer to these objects of interest as target objects. Extract the target objects in these pictures to obtain a digital image with transparent surr...
