Editor's Notes
- Challengeā¦. The currently sophisticated methods like parametric and geometric active contour models and texture measures are not efficient enough to be applied for near-real-time image processing and cannot be applied fully automatically. The only possibility here to keep up with the amount of daily incoming data during the TanDEM-X mission is to process the data fully automatically and to use a less time-consuming threshold method. In this case we apply the threshold method onā¦.
- ā¦ the amplitude image and on the coherence image as we can see here.
- As you can see all water bodies are appearing smooth and dark without any disturbances caused by wind effect, snow and ice coverage or others
