Center node: "superpixel based semantic segmentation trained by statistical process control"
  Abstract: Semantic segmentation, like other fields of computer vision, has seen a remarkable performance advance by the use of deep convolution neural networks. Many recent studies on this field upsample smaller feature maps into the original size of the image to label each pixel into one of semantic categories. However, considering that neighboring pixels are heavily dependent on each other, both learning and testing of these methods have a lot of redundant operations. To resolve this problem, the proposed network is trained and tested with only 0.37\% of total pixels by superpixel-based sampling and largely reduced the complexity of upsampling calculation. In doing so, scale and translation invariant features are constructed by making the hypercolumns using the feature maps obtained by pyramid module as well as the feature maps in convolution layers of the base network. Since the proposed method uses a very small number of sampled pixels, the end-to-end learning of the entire network is difficult with a common learning rate for all the layers, which is caused by the small sampling ratio. In order to compensate for this, the learning rate after sampling is controlled by statistical process control (SPC) of gradients in each layer. The proposed method performs better than or equal to the conventional methods that use much more samples on Pascal Context, SUN-RGBD dataset.
