The invention discloses an image segmenting method based on a data field, comprising the following steps of: defining each pixel of an image as a data object in a two-dimensional space; defining the gray value of the pixel as the quality of the data object; obtaining the potential value of each pixel by utilizing the gray value of each pixel; generating an equipotential line according to the potential value of the pixel so that an image data field is generated; and segmenting the image by utilizing the image data field. Experiments show that compared with the prior art, the image segmenting method can obtain better image segmenting effect and also has very good noise immunity.
Description
technical field [0001] The invention relates to image segmentation and object recognition in image processing, in particular to a method for realizing image segmentation by using a data field. Background technique [0002] Image segmentation refers to the technology and process of dividing the image into regions with different characteristics, and using some features in the image information to extract several objects of interest in the image (Zhang Yujin, 2001). Image segmentation is a key technology in image processing, and it is also the main problem in low-level vision in the field of computer vision, and it is also a classic problem. [0003] Data field is a physical method of uncertain knowledge discovery (Li Deyi, Du Yu, 2005). It borrows the concept of the field of physics to describe the interaction between objects. Think of concepts, language values, words in natural language, even data points in domain space, and every pixel in an image as interacting objects or...
