SwiftUI如何确定图像是在风景中拍摄还是在肖像中拍摄？

import CoreML
import Vision

func analyzeImage(_ image: UIImage) {
    guard let model = try? VNCoreMLModel(for: MyImageClassifier().model) else {
        return
    }
    
    let request = VNCoreMLRequest(model: model) { request, error in
        guard let results = request.results as? [VNClassificationObservation],
              let topResult = results.first else {
            return
        }
        
        // 根据置信度判断图像分类
        if topResult.confidence > 0.5 {
            if topResult.identifier.contains("scenery") {
                print("图像是在风景中拍摄")
            } else if topResult.identifier.contains("portrait") {
                print("图像是在肖像中拍摄")
            }
        }
    }
    
    guard let ciImage = CIImage(image: image) else {
        return
    }
    
    let handler = VNImageRequestHandler(ciImage: ciImage)
    
    do {
        try handler.perform([request])
    } catch {
        print("图像分析错误: \(error)")
    }
}
