针对热红外图像目标与背景区分不明显、效果模糊,以及传统的Roberts、Sobel、Canny 等边缘检测方法难以取得理想检测效果的特点,以玉米植株为测试对象,首次将蚁群优化算法应用于热红外图像边缘检测。该算法由初始化过程开始,进行N步迭代构造信息素矩阵,然后执行信息素过更新过程,最后图像边缘由决策过程给出。仿真实验结果表明,该算法与传统边缘检测算法相比,能够较好地得到边缘检测结果,可为农作物热红外图像处理提供一种新的方法。
針對熱紅外圖像目標與揹景區分不明顯、效果模糊,以及傳統的Roberts、Sobel、Canny 等邊緣檢測方法難以取得理想檢測效果的特點,以玉米植株為測試對象,首次將蟻群優化算法應用于熱紅外圖像邊緣檢測。該算法由初始化過程開始,進行N步迭代構造信息素矩陣,然後執行信息素過更新過程,最後圖像邊緣由決策過程給齣。倣真實驗結果錶明,該算法與傳統邊緣檢測算法相比,能夠較好地得到邊緣檢測結果,可為農作物熱紅外圖像處理提供一種新的方法。

The thermal infrared image often has the drawbacks of inconspicuous distinction between target and back -ground , fuzzy effect .The traditional edge detection methods , such as Robert method , Sobel method , Canny method , are difficult to obtain satisfactory results .In order to solve the problems , the corn plant as the test object , the ant colony op-timization algorithm is applied for the first time thermal infrared image edge detection .The algorithm begins by initializing process , carried out N-step iterative constructing pheromone matrix , and then performing the pheromone update process , finally , image edge given by the decision making process .The simulation and experimental results show that this method can accurately detect the target edge and it is better than the traditional edge detection .Provided a new method for crop thermal infrared image processing .
