Deep morphological neural networks
Mathematical morphology is a theory and technique applied to collect features like geometric and topological structures in digital images. Determining suitable morphological operations and structuring elements for a give purpose is a cumbersome and time-consuming task. In this paper, morphological neural networks are proposed to address this problem. Serving as a non-linear feature extracting layers in deep learning frameworks, the efficiency of the proposed morphological layer is confirmed analytically and empirically. With a known target, a single-filter morphological layer learns the structuring element correctly, and an adaptive layer can automatically select appropriate morphological operations. For high level applications, the proposed morphological neural networks are tested on several classification datasets which are related to shape or geometric image features, and the experimental results have confirmed the tradeoff between high computational efficiency and high accuracy
Learning Deep Morphological Networks with Neural Architecture Search
Deep Neural Networks (DNNs) are generated by sequentially performing linear
and non-linear processes. Using a combination of linear and non-linear
procedures is critical for generating a sufficiently deep feature space. The
majority of non-linear operators are derivations of activation functions or
pooling functions. Mathematical morphology is a branch of mathematics that
provides non-linear operators for a variety of image processing problems. We
investigate the utility of integrating these operations in an end-to-end deep
learning framework in this paper. DNNs are designed to acquire a realistic
representation for a particular job. Morphological operators give topological
descriptors that convey salient information about the shapes of objects
depicted in images. We propose a method based on meta-learning to incorporate
morphological operators into DNNs. The learned architecture demonstrates how
our novel morphological operations significantly increase DNN performance on
various tasks, including picture classification and edge detection.Comment: 19 page
