摘要
提出了一种提取分形尺度误差的电视图像检测分割算法。首先针对强海杂波背景特性,将多目标统归于目标类,分析了归一化的数字图像形态维分形模型,再构建分形尺度误差作为模式分类特征,并设定类间最优阈值进行分割,获得目标区域的精确位置信息,最后选取分割结果中最大局部熵点作为种子,通过区域生长得到较为完整的目标轮廓。通过对实际海景序列图像进行了仿真实验,取得了良好的检测分割效果,并具有较强的抗噪声性能。
A novel fractal segmentation algorithm is introduced to deal with multi-targets in sea surf.Based on analyzing and normalizing fractal morphology model,multi-targets are regarded as a whole class to avoid interaction.Then,a fractal feature named as Scale Error performs detection.After threshold segmenting and region growing,satisfied results are attained.A plenty of simulation experiments for recorded data approve its validity and veracity.
