Hierarchical Feature Mining for Image Classification and Segmentation

In this paper, supervised and unsupervised learning are used to classify and segment two different types of images. Specifically, first, we use our deep learning classification model to develop a fast and accurate scheme for feature extraction. We design a DCNN model that is 18 times faster than the state-of-the-art AlexNet at a small loss of accuracy. Second, different classifiers have been trained on the features that are extracted from the fully connected layer of the deep convolutional neural networks (DCNN). Finally, we perform K-means-graph-cut segmentation and qual- iteratively compare with supervised segmentation results. Image-level and region-level classification has been studied by utilizing natural scenes and biomedical image processing, respectively. Our experimental results demonstrate that the proposed method outperforms existing methods on a biomedical image dataset.
