Embodiment Construction

[0032] According to the various application requirements of the image, the user hopes to divide the large stitched image into the state before stitching as much as possible, or split it into multiple rectangular areas with independent meaning. The solution provided in the embodiment of the present application can realize the automatic segmentation processing of large-scale mosaic images. First, an image segmentation method provided in the embodiment of the present application will be described below, including the following steps:

[0033] According to the pixel characteristics of the rows and columns of the image to be segmented, determine the candidate segmentation line in the image to be segmented;

[0034] Determine the line segment between the intersection of the row and column where the candidate dividing line is located as the official dividing line of the image to be divided, and determine the line segment between the intersection of the original boundary line of the im...

Abstract

The application discloses image segmentation method and a system. The image segmentation method comprises the steps of according to the pixel characteristics of rows and lines of an image to be cut, determining an alternative cutting line in an image to be cut; determining a line section clamped by the intersection points of the row and the line on which the alternative cutting line is positioned as a formal cutting line of the image to be cut, and determining a line section clamped by the intersection points of an original border line and the alternative cutting line of the image to be cut as a formal cutting line of the image to be cut; utilizing the formal cutting line to form a rectangular region so as to store the information of the rectangular region; and cutting the rectangular region corresponding to the stored information from the image to be cut. In the technical scheme, according to the pixel characteristics of the rows and lines of the image to be cut, a possible cutting line of the image can be determined, then an independent region block in the image can be determined in the rectangular region formed by the cutting lines, and finally, the region blocks are cut from an original image, so that the automatic segmentation of a large-size splicing image can be realized.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image segmentation method and system. Background technique [0002] With the development of image processing technology, images have become an important form of information carrying in the field of computers and the Internet. [0003] Generally speaking, an image should be able to independently express relatively complete information, but in practical applications, we often encounter some large images, which are composed of multiple simple images, although the display effect is different from that of ordinary images. The image is similar, but it is not conducive to post-processing the image. For example, in application requirements such as image recognition, image classification, image retrieval, and image database establishment, operations such as image analysis and feature extraction are required. On the one hand, due to the large size of the image, image...
