Optimizing Image Retrieval with an Extended b-Metric Space

Abdelkader Belhenniche, Roman Chertovskih

TL;DR

This work introduces ${\rm NEM}_{\sigma}$, a dynamic distance measure within extended $b$-metric spaces to enhance image retrieval in QBIC systems. By replacing the fixed stretching in ${\rm NEM}_{r}$ with a velocity-/environment-aware function $\sigma$ and a modular factor $\theta$, the authors derive a generalized relaxed triangle inequality that sustains robust pattern matching in complex, dynamic contexts. They define ${\rm NEM}_{\sigma}$ via a minimal $(m,n)$-\sigma-mapping that combines a stretch cost $\mathcal{S}$ and a distance cost $\mathcal{D}$, both expressible as double integrals, and prove it forms an extended $b$-metric with $\theta(x,z)=1+\Delta(x,z)$. The framework enables finer, adaptive alignment of sequences under varying conditions, demonstrated conceptually through $\delta$-edges and velocity-aware mappings, with the potential to significantly improve large-scale image retrieval in real-world, dynamic datasets.

Abstract

This article provides a new approach on how to enhance data storage and retrieval in the Query By Image Content Systems (QBIC) by introducing the ${\rm NEM}_σ$ distance measure, satisfying the relaxed triangle inequality. By leveraging the concept of extended $b$-metric spaces, we address complex distance relationships, thereby improving the accuracy and efficiency of image database management. The use of ${\rm NEM}_σ$ facilitates better scalability and accuracy in large-scale image retrieval systems, optimizing both the storage and retrieval processes. The proposed method represents a significant advancement over traditional distance measures, offering enhanced flexibility and precision in the context of image content-based querying. Additionally, we take inspiration from ice flow models using ${\rm NEM}_σ$ and ${\rm NEM}_r$, adding dynamic and location-based factors to better capture details in images.

Key Result

Theorem 3.1

Let $X$ be nonempty sequence and let the function $\mathcal{B} \colon X \times X \rightarrow [0, +\infty)$ be an extended $b$-metric with modulus $\alpha \colon X \times X \rightarrow [1,+\infty)$. Then, for all $X, Y, Z$, the measure ${\rm NEM}_{\sigma}$ is extended b-metric.

  • Figure 1: Pattern matching with relaxed triangle inequality. (a) represents the three robots in a stable, stationary state, while in (b) and (c) the robots are in motion.
  • Figure 2: A minimal $(9,9)$-mapping with the stretch-cost of $6r$ (reproduced from FAG98, Fig. 1).
  • Figure 3: Comparison of ${\rm NEM}$ and ${\rm NEM}_r$: The left plot illustrates the alignment of a circle and an ellipse in ${\rm NEM}$, where the circle remains unchanged. In contrast, the right plot demonstrates ${\rm NEM}_r$, where a stretching penalty ($r = 1$) elongates the circle along the $y$-axis, modifying its shape to better match the dimensions of the ellipse.
