Abstract

Fuzzy image enhancement is an important method in the process of image processing. Fuzzy image enhancement includes steps: gray-level fuzzification, modifying membership using intensifier (INT) operator, and obtaining new gray-levels by defuzzification. This paper proposed an adjustable INT operator with parameter k. Firstly, the image’s pixels are divided into two regions by the OTSU method (low and high region), and calculate the pixels’ membership by fuzzification in each region. Then, the INT operator reduce pixels’ membership in the low region and enlarge pixels’ membership in the high region. The parameter k is determined base on the pixel’s location information (neighborhood information), and plays an adjusting role when the INT operator is working. And finally, the result image is obtained by the defuzzification process. In the experiment results, the fuzzy image enhancement with the adjustable intensifier operator achieves a better performance.

基于可调增强算子的模糊图像增强

模糊图像增强是图像处理过程中的一种重要方法。模糊图像增强包括灰度模糊化、使用增强算子(INT)修改隶属度、通过去模糊化获得新的灰度。本文提出了一种参数为k的可调INT算子。首先，采用OTSU方法将图像像素划分为两个区域(低区和高区)，并对每个区域进行模糊化计算像素的隶属度;然后，INT算子在低区域减少像素的隶属度，在高区域增加像素的隶属度。参数k是根据像素的位置信息(邻域信息)确定的，在INT算子工作时起调节作用。最后对结果图像进行去模糊处理。实验结果表明，采用可调增强算子的模糊图像增强效果较好。
