High-resolution remote sensing image building extraction combined with Faster-RCNN and Level-Set
the Level-Set image segmentation method has the problem that the initial contour is greatly affected by human factors. The target segmentation and the target and background gray values are close to each other
and the ideal segmentation effect cannot be achieved. Aiming at this problem
this paper proposes a priori level set image segmentation method based on the Faster-RCNN network model to determine the initial contour and region information of the target
and builds the Caffe deep learning framework to train the Faster-RCNN network model. The IAILD data is obtained through supervised learning. The training model is assembled
the target building is detected and the outline of the building is initially extracted and combined with the shape-priority Level-Set algorithm. The experimental results show that the proposed method solves the problem that the initial contour of the image segmentation result is greatly influenced by the artificial marker frame selection in the Level-Set algorithm. It can better complete the segmentation of the occluded building
and achieve better segmentation effect for the target building and the background gray value.
