Embodiment Construction

[0045] Such as figure 1 As shown, an embodiment of the present invention is shown, a method for image segmentation based on a modified gradient image and a watershed algorithm, comprising steps:

[0046] S100: Obtain a gradient image of an image to be segmented.

[0047] S200: Perform distance transformation on the image to be segmented, and obtain a first transformation map of the image to be segmented.

[0048] S300: Convert the first transformation map to obtain a second transformation map of the image to be segmented.

[0049] S400: Extract a foreground marker of an image to be segmented according to the first transformation map or the second transformation map.

[0050] S500: Perform watershed transformation on the second transformed image, and extract background markers of the image to be segmented.

[0051] S600: Correct the gradient image according to the foreground mark and the background mark to obtain a corrected gradient image.

[0052] S700: Perform watershed ...

Abstract

The present invention relates to an image segmentation method and system, and a cell image segmentation method and system based on a corrected gradient image and a watershed algorithm. Since a gradient image of a to-be-segmented image is corrected in advance by a foreground mark obtained by distance transformation and a background mark obtained by watershed transformation and then the corrected gradient image is subjected to watershed transformation to obtain an image segmentation result, not only are the advantages of performing watershed transformation on the gradient image, effectively locating the edges of a target object and segmenting out a complete outline of the target object reserved, but also targets with no obvious boundaries in adhesion areas can be distinguished by the foreground mark and the background mark, the phenomena of under-segmentation and over-segmentation do not occur, and the accuracy of image segmentation is improved. Therefore, the methods and the systems are especially suitable for the field of adhesive and overlapped cell image segmentation.

Description

technical field [0001] The invention relates to the field of image engineering, in particular to an image segmentation method and system, and a cell image segmentation method and system. Background technique [0002] In the field of image engineering, it is often necessary to separate the cohesive objects independently. Taking medical image engineering as an example, it is often necessary to automatically analyze the cell morphology, quickly and accurately segment complete cells from the cell microscopic image and perform cell analysis. However, blood cells often appear to adhere and overlap, so accurately segmenting and counting the adhered cells is a difficult point and research focus in medical image processing. [0003] In recent years, the watershed transform technology based on mathematical morphology has been applied to the segmentation of cohesive objects. The watershed transform algorithm, etc., is rigid in the segmentation of the cohesive target, and cannot fully ...
