Special Issue Information

Dear Colleagues,

We extend to you an invitation to participate in our Special Issue titled Applications of Mathematical Models in Image Processing and Algorithm Theory for the Mathematics journal. This Special Issue aims to present high-impact scientific contributions related to the development, analysis, and application of mathematical models in the field of image processing and computer vision. We invite the academic community, as well as industry professionals, to submit works that address current challenges and propose innovative solutions from a mathematical and computational perspective.

This Special Issue is set to include papers ranging from fundamental theoretical research to practical applications in various domains, as well as review articles and case studies that provide a comprehensive overview of the state of the art. Particular value will be given to contributions that stand out for their originality, methodological rigor, and potential for real-world implementation.

This collection seeks to strengthen interdisciplinary dialogue among applied mathematics, engineering, computer science, and cognitive sciences, thereby advancing knowledge in modern techniques for image analysis and processing, pattern recognition, segmentation, 3D reconstruction, deep learning, and computer vision.

The Hough transform (HT) is widely used in computer vision, tomography, and neural networks. Numerous algorithms for HT computation have been proposed, making their systematic comparison essential. However, existing comparative methodologies are either non-universal and limited to certain HT formulations or task-oriented, relying on application-specific criteria that do not fully capture algorithmic properties. This paper introduces a novel unified methodology for the systematic comparison of HT algorithms. It evaluates key characteristics, including computational complexity, accuracy, and auxiliary space complexity, while explicitly accounting for the property of self-adjointness. The methodology integrates both implementation-level and theoretical considerations related to the interpretation of HT as a discrete approximation of the Radon transform. A set of mathematically justified evaluation functions, not previously described in the literature, is proposed to support our methodology. Importantly, the methodology is universal, applicable across diverse HT paradigms, encompasses pattern-based and Fourier-based fast HT (FHT) algorithms, and offers a comprehensive alternative to existing task-specific methodologies. Its application to several state-of-the-art FHT algorithms (FHT2DT, FHT2SP, ASD2, KHM, and Fast Slant Stack) yields new experimentally confirmed theoretical insights, identifies ASD2 as the most balanced algorithm, and provides practical guidelines for algorithm selection. In particular, the methodology reveals that for image sizes up to 3000, the maximum normalized computational complexity increases as follows: FHT2DT (1.1), ASD2 (15.3), and KHM (30.6), while the remaining algorithms exhibit at least 1.1 times higher values. The maximum orthotropic approximation error equals 0.5 for ASD2, KHM, and Fast Slant Stack; lies between 0.5 and 1.5 for FHT2SP; and reaches 2.1 for FHT2DT. In terms of worst-case normalized auxiliary space complexity, the lowest values are achieved by FHT2DT (2.0), Fast Slant Stack (4.0, lower bound), and ASD2 (6.8), with all other algorithms requiring at least 8.2 times more memory.
