Embodiment Construction

[0061] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] (1) Enhance the collected blood cell image:

[0063] The collected images of peripheral blood leukocytes are enhanced, including converting color images to grayscale images and filtering to reduce noise. It lays a foundation for further image processing. The conversion formula for converting a color image to a grayscale image is:

[0064] f(x,y)=R(x,y)×0.2989+G(x,y)×0.0.5870+B(x,y)×0.1140 (1)

[0065] Among them: f(x,y) is the gray value of the grayscale image at point (x,y); R(x,y), G(x,y), B(x,y) are the color image at Red (Red), Green (Green), Blue (Blue) component values ​​at position (x,y).

[0066] The median filtering method is adopted in the noise filtering step. The median filtering method can suppress the interference pulse and point noise and keep the edge of the image better. In the specific implementation, th...

Abstract

The invention discloses a method for extracting peripheral blood leucocyte edges with application of quaternion edge detection and graph theory optimization. The method comprises the steps of image preprocessing used for improving an image signal to noise ratio, cell window positioning used for acquiring a square area only containing one white blood cell, white blood cell karyon contour extraction and linking achieved by applying a orthogonal wavelet packet multiscale analysis and chain code method, cytoplasm contour fragment acquisition through applying quaternion edge detection, and cytoplasm contour linking achieved by applying a graph theory optimization method. According to the method, the division extraction of the peripheral blood leucocyte edges is achieved by synthesizing extraction and linking results of white blood cell karyons and cytoplasm edges.

Description

technical field [0001] The invention belongs to the field of image analysis, and relates to a peripheral blood leukocyte edge extraction method, in particular to a method for peripheral blood leukocyte edge detection and linking using a quaternion edge detection and graph theory optimization method. Background technique [0002] Blood routine examination is an important auxiliary means for doctors to diagnose. Hospitals now generally use blood routine testing instruments for blood routine examinations. The blood routine detector mainly completes the statistics of various blood cells by analyzing the photoelectric effect of different types of blood cells when they pass through the set micropores. Technically, due to the extraction of too few cell features, the general classification accuracy is not high, and the function is relatively simple. The detection results are usually used as the preliminary judgment basis for disease diagnosis. In practical application, in order to...
