Abstract Metaheuristic algorithms have applicability in various fields where it is necessary to solve optimization problems. It has been a common practice this field for several years propose new that take inspiration from natural and physical processes. The exponential increase of controversial issue researchers criticized. However, their efforts point out multiple issues involved these practices insufficient since the number existing metaheuristics continues yearly. To know current state problem, paper analyzes sample 111 recent studies so-called new, hybrid, or improved are proposed. Throughout document, topics reviewed will be addressed general perspective specific aspects. Among study’s findings, observed only 43% analyzed papers make some mention No Free Lunch (NFL) theorem, being significant result ignored by most presented. Of studies, 65% present an version established algorithm, which reveals trend no longer based on analogies. Additionally, compilation solutions found engineering problems commonly used verify performance state-of-the-art demonstrate with low level innovation can erroneously considered as frameworks years, known Black Widow Optimization Coral Reef analyzed. study its components they do not any innovation. Instead, just deficient mixtures different evolutionary operators. This applies extension recently proposed versions.

ReTrackVLM: Transformer-Enhanced Multi-Object Tracking with Cross-Modal Embeddings and Zero-Shot Re-Identification Integration

Applied Sciences, Год журнала: 2025, Номер 15(4), С. 1907 - 1907

Опубликована: Фев. 12, 2025

Multi-object tracking (MOT) is an important task in computer vision, particularly complex, dynamic environments with crowded scenes and frequent occlusions. Traditional methods often suffer from identity switches (IDSws) fragmented tracks (FMs), which limits their ability to maintain consistent object trajectories. In this paper, we present a novel framework, called ReTrackVLM, that integrates multimodal embedding visual language model (VLM) zero-shot re-identification (ReID) module enhance accuracy robustness. ReTrackVLM leverages the rich semantic information VLMs distinguish objects more effectively, even under challenging conditions, while ReID mechanism enables robust matching without additional training. The system also includes motion prediction module, powered by Kalman filtering, handle occlusions abrupt movements. We evaluated on several widely used MOT benchmarks, including MOT15, MOT16, MOT17, MOT20, DanceTrack. Our approach achieves state-of-the-art results, improvements of 1.5% MOTA reduction 10. 3% IDSws compared existing methods. excels precision, recording 91.7% precision MOT17. However, extremely dense scenes, framework faces challenges slight increases IDSws. Despite computational overhead using VLMs, demonstrates track effectively diverse scenarios.
