                        path of train data

How to use this in your code

Use existing image to train classification model

  segmenter = NormalSegmenter()
  extractor = SimpleFeatureExtractor(feature_size=20, stretch=False)
  analyzer = KNNAnalyzer(segmenter, extractor)
  analyzer.train('data/features.jpg')

• Use classification model to test your own images

  result = analyzer.analyze('data/example.jpg')
