Problems solved by technology

[0002] For a long time, the tobacco leaf grading at the tobacco leaf purchasing station has relied on the experience of the graders to touch, see, and smell. There are problems such as heavy workload, subjective factors and experience, and inconsistent grading standards. The phenomenon of non-compliance with grades has brought adverse effects on the acquisition work

Embodiment Construction

[0025] Embodiment of the present invention: a method for synthesizing a standard grade tobacco leaf image database based on digital image processing technology, as shown in the attached figure 1 shown, including the following steps:

[0026] Step 1: Take pictures of standard-grade tobacco leaf samples to obtain tobacco leaf sample images. Photo sampling refers to taking three pictures of each tobacco leaf sample, and selecting the one with the best effect as the tobacco leaf sample image.

[0027] Step 2: Use image processing software to select a relatively representative area on the obtained tobacco leaf sample image.

[0028] Step 3: Perform image preprocessing operations on the region images obtained in step 2 respectively to obtain clear tobacco leaf sample region images;

[0029] Wherein the image preprocessing comprises the following steps;

[0030] 1. Decompose the image of the tobacco leaf sample area into R, G, and B three-channel image data;

[0031] 2. Use median...

Abstract

The invention discloses a method for synthesizing a standard-grade tobacco leaf image database based on digital image processing technology. The standard-grade tobacco leaf sample is photographed to obtain the tobacco leaf sample image, and then the image processing software is used to select a relatively representative area. The image preprocessing operation is to obtain a clear image of the tobacco leaf sample area, and the clear image of the tobacco leaf sample area is binarized to obtain a binary image, and the binary image is reversed to obtain a binary image template. The channel is used to extract color features, and the extracted tobacco leaf color feature values ​​are used to synthesize standard-grade tobacco leaf images to construct a tobacco leaf image database. The present invention utilizes digital image processing and image feature recognition technologies to construct a standard-grade tobacco leaf image database, which can realize the scientific classification of flue-cured tobacco leaves. Quantification greatly reduces the workload in the purchase of tobacco leaves, and the product classification accuracy is high.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a method for synthesizing a standard grade tobacco leaf image database based on digital image processing technology. Background technique [0002] For a long time, the tobacco leaf grading at the tobacco leaf purchasing station has relied on the experience of the graders to touch, see, and smell. There are problems such as heavy workload, subjective factors and experience, and inconsistent grading standards. The phenomenon of non-compliance with grades has brought adverse effects to the acquisition work. [0003] With the continuous improvement of the level of industrialization, image processing technology is widely used in monitoring, medical equipment, military and other industries, and image processing technology is getting more and more attention. Contents of the invention [0004] The purpose of the present invention is to: provide a method for synthesizing a ...
