| 中文摘要: |
| 数学形态滤波中结构的大小和形状不同，处理遥感图像获得的效果也不同。为了更好地理解结构元素的大小和形状对图像边界提取效果的影响，通过实验对比法，从简单到复杂地进行了分析。实验结果表明，道路等规则条状地物适合用线形结构元素，房屋等规则或近似规则的建筑物适合用方形结构元素，各项异性不明显的高分影像适合用圆形结构元素；结构元素的尺寸越大，损失的细节就越大，但是能去除更大的噪声点。 |
| 英文摘要: |
| In mathematical morphological filtering, different structural sizes and shapes lead to the different processed remote-sensing images. A study on the effect of the size and shape of the structural elements on the image edge extraction is carried out successively through experimental comparison. The results show that roads and other regular strip objects are suitable for linear structural elements, buildings and other regular or approximately regular objects are suitable for square structural elements, and various irregular high-resolution images are suitable for circular structural elements. The larger the size of the structural element is, the greater the loss of details is, but more noise points can be removed. |
