研究目的
To recognize windmills in remote sensing images using SVM and morphological attribute filters due to their small area and quantity, which make traditional methods unsuitable.
研究成果
The proposed technique effectively recognizes windmills with high accuracy, low false-alarm rates, and minimal miss probabilities, demonstrating the utility of combining SVM and morphological attribute filters for small target recognition in remote sensing.
研究不足
The technique may be limited by the quality and resolution of remote sensing images, and the specificity to windmills might not generalize well to other small objects. Potential optimizations could include handling more diverse environmental conditions or improving filter parameters.
1：Experimental Design and Method Selection:
The technique involves two main steps: preliminary classification using SVM based on spectral information to identify windmill-like areas, followed by application of morphological attribute filters to filter out non-windmill areas based on shape characteristics.
2：Sample Selection and Data Sources:
Remote sensing images from four regions (A to D) with wind power plants were used, containing bands blue, green, red, and near infrared. Training samples included various area types such as factory roof, woodland, cement road, water, and windmills.
3：List of Experimental Equipment and Materials:
Remote sensing images and a computer for processing; no specific equipment brands or models are mentioned.
4：Experimental Procedures and Operational Workflow:
Extract spectral information from images, train SVM classifier, classify images to get regions of interest (ROI), apply morphological attribute filters (e.g., area filters, line number filters, vertex number filters, height filters) to refine ROI and remove non-windmill areas.
5：Data Analysis Methods:
Calculate accuracy, false-alarm rate, and probability of miss for the recognition results in the four regions.
