Embodiment Construction

[0039] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation of the present invention is not limited thereto.

[0040] Such as figure 1 , the main flow of the slender connected region extraction method for digital images includes the following steps:

[0041] (a) Read an image of an egg with a light on its back.

[0042] (b) Detecting the embryo region according to the image read in step (a), and performing rotation correction and cropping on the region;

[0043] (c) performing image enhancement processing on the embryo image obtained in step (b), expanding the difference between embryonic blood vessels and non-vascular areas;

[0044] (d) performing blood vessel detection on the enhanced embryo image obtained in step (c);

[0045] (e) according to the result of step (d), post-processing the embryo blood vessel detection result;

[0046] (f) According to the result of step (e), count t...

Abstract

The invention relates to a method for extracting slender connected regions of digital images. It belongs to the field of digital image processing. In the method, the image to be detected is input, and the detected connected region information is finally output through four steps of interest region detection and extraction, image enhancement, elongated connected region detection, and elongated connected region detection result post-processing . The invention utilizes the image enhancement technology and the digital image morphology processing technology, and can realize the automatic blood vessel detection of the poultry egg embryo under the condition that the normal development of the poultry egg embryo is not affected. The invention overcomes the defects of the invasive poultry egg blood vessel measurement method represented by manual dissection, such as long time consumption, high cost, and damage to the development of poultry egg embryos, and realizes fast and accurate detection of poultry egg embryo blood vessels that does not affect embryo development, and provides a new method for poultry breeding. The automated poultry egg screening in provides an effective solution.

Description

technical field [0001] The invention generally relates to the field of computer vision, in particular to a method for extracting elongated connected regions of digital images. Background technique [0002] With the development of poultry farming technology, poultry has become an important food source for humans. Determining the quality of poultry egg embryo development is a key issue in poultry breeding, which plays an important role in improving the quality of breeding and reducing the cost of breeding. Among them, the length and thickness of poultry egg embryo blood vessels determine the development quality of poultry egg embryos, and then an important indicator for poultry egg screening. Traditional poultry egg embryo blood vessel detection methods (such as manual dissection) will destroy the poultry egg embryo structure, which not only takes a long time to detect, but also It is necessary to manually operate each poultry egg, and the cost of required human resources is ...
