Mathematical methods for signal and image processing present the mathematical methodology for generic image and signal analysis tasks.The existing literature on image methodology is rather scattered.This special issue brings together some seemingly different points of view to stress their conceptual relations and analogies.In this issue, some papers focus on specific applications, while some other papers discuss the methodological frameworks on which specific applications are built.Covering many topics at the forefront of current research, this issue will be of particular interest to researchers in the fields of computer vision, image processing, signal processing, medical imaging, visual perception, pattern recognition, and so on.
Among the 16 exciting papers compiled in this special issue, two papers discuss fundamental mathematical concepts.J.-J.Yao and Z.-L.Jiang consider the skew circulant and skew left circulant matrices with continuous Lucas numbers.They discuss the invertibility of the skew circulant matrices and present the determinant and the inverse matrices by constructing the transformation matrices.In the area of image encryption and image coding, S. Zhang et al. propose a joint encryption and reversible data hiding scheme.R. Gomathi and A. Vincent Antony Kumar introduce a new framework for image coding that uses image inpainting method.In the proposed algorithm, the input image is subjected to image analysis to remove some of the portions purposefully.
There are two papers in the area of communication signal processing.J. Wang et al. discuss 60 GHz wireless communications over the additive white Gaussian noise channel.Channel capacity with quadrature amplitude modulation (QAM) is investigated for the unlicensed 59-64 GHz radio spectrum set aside by FCC.Their results prove that QAM is an attractive scheme for 60 GHz wireless communications.D. Yumin and X. Shufen propose quantum random walk optimization model and algorithm in network cluster server traffic control and task scheduling.
Two papers deal with image retrieval and image matching.M. Xiao et al. propose new optimization strategies on vocabulary tree building, retrieval, and matching methods.F. Nayyeri and M. F. Nasrudin study image matching by using dimensionally reduced embedded earth mover's distance.
In the area of image recognition and image reconstruction, M. A. By compiling these papers, we hope to enrich our readers and researchers with respect to the advances in mathematical methods for image and signal processing.
