摘要 针对SAR影像边缘检测结果,提出了一种定量的质量评估方法。该方法不需要边缘基准图等先验知识,而是通过计算评估窗口内边缘点的方向一致性指标与边缘形态指标,并将其组合得到最终的评估得分值。初步的实验结果表明,方法对SAR边缘检测的评估结果与人工判读的结果比较接近,与边缘质量评估的主观判断结论相吻合。该方法自动化程度高,评价结果客观合理,有较强的工程应用性。 A method for quality evaluation of SAR edge detection is proposed,which needs no standard edge reference.Firstly, test edge results are extracted by ROA and Tupin algorithms from SAR image.Then,indices of direction consistency and edge form are computed in evaluation windows.Finally,evaluation score is obtained by combining above two indices.The experimental results show that the method’s result is consonant with result of manual interpretation and subjective judgment. This method possesses high automation,objective result and practical implementation.
