摘要:

分析了基于Retinex理论图像增强算法和传统的Canny边缘检测算法,提出将2种方法有效结合起来,应用于曝光不均匀、图像模糊不清或者对比度低图像的边缘检测中。实验表明该方法能准确检测图像中的目标边缘,比单一应用Canny算法检测到的边缘细节更丰富,且能较好地保持目标边缘的连通性。

关键词: Retinex理论, 图像增强, Canny算法, 边缘检测

Abstract:

In this paper,the image enhancement algorithm based on Retinex theory and the traditional Canny edge detection algorithm is analyzed.The new method was proposed by effectively combined the two methods to apply to the exposure of uneven,blurred images,or low contrast images.The experimental results show that the method can accurately detect the image edge of the target,more abundant than the only application of the Canny algorithm to detect the edge details,and can maintain good goal edge connectivity.

Key words: Retinex theory, imagee nhancement, Canny algorithm, edgede tectio
