| 摘 要： | 为了给生产单位害虫管理的普通技术人员提供简便易操作的昆虫鉴别方法, 本文提出了一种新颖的基于图像颜色及纹理特征的昆虫图像识别方法。鳞翅目昆虫翅面图像经过预处理, 确定目标区域, 再进行特征提取。首先将彩色图像从三原色(red-green-blue, RGB)空间转换至色调饱和值（HSV）空间并提取有效区域内的色度、饱和度直方图特征, 然后经图像位置校准, 提取灰度图的双树复小波变换（DTCWT）特征; 匹配首先计算两颜色直方图特征向量之间的相关性, 将相关性大于阈值的样本再进一步用DTCWT特征匹配; DTCWT匹配通过计算Canberra距离实现, 从通过第一层颜色匹配的样本中取出最近邻作为最终匹配类别。算法在包含100类鳞翅目昆虫的图像库中进行试验验证, 取得了76%的识别率, 其中前翅识别率则达92%, 同时取得了理想的时间性能。试验结果证明了本文方法的有效性。

| Abstract: | This study aims to provide general technicians who manage pests in production with a convenient way to recognize insects. A novel method to classify insects by analyzing color histogram and dual tree complex wavelet transform (DTCWT) of wing images was developed. The wing image of lepidopteran insect is preprocessed to get the region of interest (ROI). First,the color image is converted from red-green-blue (RGB) to hue-saturation-value (HSV) space,and the 1D color histogram of ROI is generated from hue and ... |
