Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] A method for establishing boundary-based leukocyte segmentation evaluation criteria, such as figure 1 shown, including the following steps:

[0044] Step S1. For the result of expert segmentation, the intermediate variable target is obtained by expanding morphology and selecting appropriate structural elements.

[0045] In step S1, for a white blood cell picture, such as figure 2 As shown, the result of expert segmentation is obtained, such as image 3 As shown, denoted as G, the result of using the algorithm segmentation, such as Figure 4 Shown, denoted as C.

[0046] Perform morphol...

Abstract

The invention provides a boundary-based white cell segmentation evaluation standard establishment method. The method includes firstly establishing an intermediate variable after processing expert segmentation results in a horologic manner, and allowing micro differences to exist between two segment results; finding out the corrective segmenting portion, the unsegmented portion and the segmented residual portion according to the segmentation results by the algorithm and the set relationships of the intermediate variable; converting the portions into boundaries segmented by the algorithm and boundaries segmented by the experts through morphological reconstruction and set calculation, counting the number of pixels of the boundaries, calculating a measure F, and evaluating the algorithm segmentation effect. The algorithm is simple and effective; compared with the existing evaluation standard based on regions, the method has the advantages that the boundary information can be well described, and the boundary micro differences can be ignored.

Description

technical field [0001] The invention belongs to the field of medical image processing, in particular to a method for establishing a boundary-based white blood cell segmentation evaluation standard. Background technique [0002] Cell segmentation is an important step in the automatic identification of white blood cells and the basis for subsequent cell identification. Due to the complex characteristics of blood cells and the uncertainty of microscopic pictures, and cells often overlap, and the contrast between cell boundaries and background is not obvious, cell segmentation is a big challenge in image processing, and it is also a very active field. research direction. Although a variety of segmentation schemes have been proposed in this field, there is no reasonable objective evaluation standard for the quality of white blood cell segmentation. [0003] Most of the current evaluation criteria for segmentation are based on natural images, but due to the complexity of natural...
