Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0056] Such as figure 1 As shown in the flow chart, the present invention comprises the following steps:

[0057] Step (1): Input the original image, perform superpixel segmentation on the original image, and record the relevant situation of the superpixel;

[0058] Step (2): For the image segmented in step (1), calculate the geodesic distance of each superpixel;

[0059] Step (3): Using the geodesic distance of each superpixel obtained in step (2) to calculate the generation area of ​​each superpixel;

[0060] Step (4): Calculate the boundary length of each superpixel using the generated area of ​​each superpixel obtained in step (3);

[0061] Step (5): use the results of step (3) and step (4) to calculate the boundary connectivity value of each superpixel; enter step (7);

[0062] Step (6): Carry out saliency detection to the original image to obt...

Abstract

The invention discloses a robust automatic image salient region segmenting method. The robust automatic image salient region segmenting method includes the steps of firstly, subjecting an image to superpixel segmenting to obtain geodesic distances, generating regions, boundary length and boundary communication values of image superpixels; secondly, subjecting an original input image to superpixel segment by an HSLIC (hexagonal simple linear iterative clustering) method, performing overall saliency detection by an SC (superpixel contrast) method to obtain a salient image of the image; finally, adopting the boundary communication values and a saliency value of the salient image, performing image segmenting and outputting a salient region segmenting result of the image. The robust automatic image salient region segmenting method has the advantages that the boundary communication values, the image saliency value and the image segmenting method are combined, and the image salient region segmenting result can be obtained by the aid of an automatic image segmenting technology.

Description

technical field [0001] The invention is mainly used in the technical field of image processing and target recognition, and is specifically a robust automatic segmentation method for image salient regions. Background technique [0002] The detection of image salient regions is an important research direction in the field of image processing. Image salient regions are often the most attention-getting parts, which contain most of the information of an image. Therefore, it has a wide range of application backgrounds. Generally, it can be used in the fields of object recognition, image segmentation, adaptive compression, image retrieval, etc. An effective detection method of image salient regions is of great help to the development of these fields. [0003] At present, there are many different salient region detection methods, which are mainly divided into two general directions: methods based on local contrast and methods based on global contrast. The method based on local cont...
