With the help of the search technique based on traditional optimal methods , gradient operator cross search operator and evolution operator are exploited to strengthen the local search ability of genetic algorithm 第3章借鉴了传统优化方法中的搜索技术,开发了梯度算子、正交搜索算子和进化算子以强化遗传算法的局部搜索能力。
In this paper the detection result of some gradient operators and laplacian are also compared with the result of bp fusion model to analysis the fusion effect . at last the paper pointed out that the fusion model has higher accuracy and higher speed in the processing of oil spill image ' s edge detection 文章最后把经五个简单算子和bp融合模型处理过的边缘图像放在一起并进行了比较,得出溢油图像经该模型处理后基本收到了预想的效果。
By means of multi - resolution analysis concept for auto - zooming of wavelet transformation , a multi - resolution gaussian gradient operator which is suitable for noisy edge detection is configured . the experiment results show that this method is an automatic rapid and effective target detection method 该方法利用小波变换的自动变焦的多分辨分析思想,构造了适合的噪声中边缘检测的多分辨率高斯梯度算子。实验结果表明,该方法是一种快速、有效的自动化目标检测方法。
