Embodiment Construction

[0051] Step 1. Image enhancement: Through the processor and adopt a fuzzy logic -based image enhancement method, the enhanced processing needs to be processed. The process is as follows:

[0052] Step Ⅰ, transform from image domain to fuzzy domain: according to the affiliated degree function μ gh = T ( x gh ) = x gh / X T x gh ≤ X T x gh / X ...

Abstract

The invention discloses an image enhancement and partition method, which comprises the following steps of I, image enhancement: a processor and an image enhancement method based on fuzzy logic are adopted for performing enhancement processing on an image needing to be processed, and the process is as follows: i, converting from an image domain to a fuzzy domain: mapping the grey value of each pixel point of the image needing to be processed to a fuzzy membership degree of a fuzzy set according to a membership function (shown in the specifications); ii, performing fuzzy enhancement processing by utilizing a fuzzy enhancement operator in the fuzzy domain; iii, converting from the fuzzy domain to the image domain; II, image partition: partitioning a digital image subjected to enhancement processing, i.e. a to-be-partition image, according to an image partition method based on a three-dimensional fuzzy division maximum entropy. The method is simple in steps, reasonable in design, convenient to realize, good in processing effect and high in practical value, and an image enhancement and partition process can be simply, conveniently and quickly completed with high quality.

Description

Technical field [0001] The invention is the field of image processing technology, especially in an image enhancement and segmentation method. Background technique [0002] The fire is one of the major mines, which seriously threatens the safety of human health, natural environment and coal mines.With the advancement of science and technology, the automatic fire detection technology has gradually become an important means for monitoring and fire warning.Nowadays, under the coal mines, the fire prediction and detection are mainly based on the temperature effect of the fire, the combustion generic (the effect of smoke and the gas) and the electromagnetic radiation effect, but the existing detection methods are in terms of sensitivity and reliability in terms of sensitivity and reliabilityIt is still necessary to improve and cannot respond to early fire, so it is not compatible with the increasingly strict fire safety requirements.Especially when there is a blocking material in the l...
