Abstract

The invention provides a method and device for segmenting an image. The method and device for segmenting the image solves the problem that an image segmenting method in the prior art is low in efficiency. The method comprises a step of downsampling an input image to obtain a preprocessed image, a step of establishing an image date model according to the preprocessed image, a step of determining the edge outline of a target image based on the calculation of the image data model, a step of determining the position where the target image is located in the input image according to the position where the edge outline is located in the preprocessed image, and a step of extracting the target image according to the position where the target image is located in the input image. By the adoption of the technical scheme, the calculated amount in the process of segmenting can be reduced, the speed of segmenting the image can be increased, and the segmenting time can be effectively saved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image segmentation method and device. Background technique [0002] In the process of digital image application, people are often only interested in certain parts of an image, and these interested parts generally correspond to specific areas with special properties in the image, which are called target images or foregrounds; The part is called the background of the image. In order to identify and analyze the target image, it is necessary to segment the target image from the original image, so as to perform post-processing on the target image. Extracting the desired target image from images and videos is the prerequisite for editing, modifying and producing images and videos. [0003] At present, there are many methods of image segmentation: [0004] The Magic Wand method calculates an area composed of connected pixels through the points or areas specified by the user. In thi...
