研究目的
To solve the problems of salt and pepper errors and low boundary adherence in superpixel-based CNN classification by proposing a region-based majority voting CNN that combines the idea of GEOBIA and deep learning technique.
研究成果
The proposed RMV-CNN method for VHRI classification, combined with the GEOBIA multiresolution segmentation and region majority voting, effectively utilizes deep features in VHRI, improves classification accuracy and boundary fit, and presents a fault-tolerant advantage owing to region majority voting. However, the selection of scale is an issue of great significance when the RMV-CNN algorithm is applied, and the scale effect still evidently affects the classification results.
研究不足
The performance of RMV-CNN classification is very dependent on segmentation, and there is no segmentation algorithm that perfectly meets the requirements of ensuring small objects are clearly segmented and preventing large objects from being over-segmented. Additionally, the scale effect still evidently affects the classification results of the RMV-CNN.
