In TD-CEDN, we initialize our encoder stage with VGG-16 net[27] (up to the pool5 layer) and apply Bath Normalization (BN)[28], to reduce the internal covariate shift between each convolutional layer and the Rectified Linear Unit (ReLU). We fine-tuned the model TD-CEDN-over3 (ours) with the NYUD training dataset. We develop a deep learning algorithm for contour detection with a fully convolutional encoder-decoder network. Contents. BN and ReLU represent the batch normalization and the activation function, respectively. The curve finding algorithm searched for optimal curves by starting from short curves and iteratively expanding ones, which was translated into a general weighted min-cover problem.

This work shows that contour detection accuracy can be improved by instead making the use of the deep features learned from convolutional neural networks (CNNs), while rather than using the networks as a blackbox feature extractor, it customize the training strategy by partitioning contour (positive) data into subclasses and fitting each subclass by different model parameters.
