Mathematical Methods in Image Processing under Uncertainty (MAMIPU) Science fund of the Republic of Serbia

Project Description

The project “Mathematical Methods in Image Processing under Uncertainty” consists of three main research directions related to related to image analysis, digital topology, fuzzy metrics, optimization techniques, and bioinformatics.

1. Computational and Digital Geometry and Topology

This part of the project focuses on computational and digital geometry and topology in the context of image analysis and processing. The research includes:

  • Novel algorithms for moments computation
  • Detecting and drawing non-self-crossing digital curves
  • Improving the performance of existing 2D image repairing algorithms
  • Computation of orthogonal hulls of 2D images
  • Applications of persistent homology
  • Investigation of the fixed point property (FPP) in digital geometry and topology

2. Fuzzy Metrics, Fuzzy Shapes, and Image Processing

This research direction studies fuzzy distances, fuzzy shapes, and aggregation-based methods. The main topics include:

  • Construction and analysis of fuzzy metrics using aggregation functions
  • Development of new classes of fuzzy shapes and descriptors
  • Theoretical and empirical analysis of associated measures
  • Applications in image compression using fixed point theory in fuzzy metric spaces

3. Hybrid Models, Optimization, and Bioinformatics

The third part of the project investigates hybrid intelligent systems and optimization techniques. It includes:

  • Hybrid models for uncertainty handling in image segmentation
  • Design and implementation of Bee Colony Optimization (BCO) algorithms
  • Learning-based clustering methods
  • Optimization of neural networks on bioinformatics data

The experimental verification of the results relies on digital image datasets obtained from publicly available databases and authorized external sources.

Title of Paper: FIXED POINT THEORY IN FUZZY METRIC SPACES WITH APPLICATION TO IMAGE PROCESSING 

Authors: T. Došenović, N. Ralević, A. Kršić, M. Paunović, Đ. Dragić

Abstract: Fixed point theory in metric spaces as well as in spaces that represent the generalization of metric spaces is one of the most important areas of nonlinear analysis. There are numerous applications of this theory, such as: solving wide classes of differentials equation, optimization problems, theory of equilibrium, image processing and many other disciplines. In this paper we deal with fixed point theory in the frame of fuzzy metric spaces, where a new class of contractive mappings is introduced and the fixed point theorem for that class of mappings is proved. An example confirming the validity of the results is shown. Appropriate fuzzy metrics are applied to image processing.

Title of Paper: APPLICATION OF FUZZY METRIC SPACES IN IMAGE PROCESSING AND FIXED POINT RESULTS

Authors: T. Došenović, N. Ralević, A. Kršić, M. Paunović, Đ. Dragić

Abstract: The study of fixed point theory in metric spaces and its generalizations plays a crucial role in nonlinear analysis. This paper focuses on fixed point theory in the context of fuzzy metric spaces, introducing a novel class of contractive mappings and establishing a fixed point theorem for this class. An illustrative example is presented to validate the theoretical results, with implications for image processing using appropriate fuzzy metrics.

Title of Paper: Construction of distance functions on a set of fuzzy numbers

Authors: Lj. Nedović, Đ. Dragić, N. Ralević, A. Blesić

Abstract: In this paper, we present a new method of construction of the distance function between fuzzy numbers, i.e., the measure of difference between the two of them. This method is based on the application of some aggregation functions on differences of certain fuzzy number parameters and characteristics. Various types of mean values and measures of dispersion are characteristics that are relevant for determining the difference between two fuzzy numbers. To determine the distance (i.e., difference) between the two of them, in this paper we use some their known characteristics, and we define several new ones.
