Bio-Inspired Signal Processing on Image and Audio Data

Dear Colleagues,

Bio-inspired signal processing, grounded in evolutionary computation, cellular automata, and neuromorphic computing, provides powerful paradigms for solving complex and uncertain real-world signal processing problems. By simulating the collective behaviors of simple biological agents and leveraging parallel, self-organizing, and hybrid optimization mechanisms, these approaches enable adaptive, robust, and energy-efficient intelligent systems.

Inspired by biological perception and neural computation, bio-inspired models exhibit complex spatiotemporal dynamics, distributed representations of information, and event-driven processing, while supporting effective cooperation and integration across multimodal signals. Such mechanisms enhance optimization capability, interpretability, and scalability in processing images, audio, and time series data under dynamic and resource-constrained environments.

In this context, this Special Issue aims to present diverse bio-inspired approaches in signal processing. Potential topics include, but are not limited to, the following:

1. Genetic and evolutionary algorithms for adaptive optimization broadly applied to image and audio (and other time series) signal processing under complex and uncertain environments.
2. Cellular automata-based models for distributed, parallel, and self-organizing representation learning, enabling formation of complex spatiotemporal patterns and robust signal analysis.
3. Neuromorphic/neuro-inspired computing and spiking neural network models for energy-efficient, event-driven processing of sensory signals, supporting real-time and low-power intelligent systems that process sensor data in real time.
4. Bio-inspired mechanisms for integrating heterogeneous sensory signals, enabling cooperative multimodal perception and improved interpretability in complex naturalistic environments.
5. Interpretable bio-inspired signal processing frameworks that enhance robustness, scalability, and reliability through biologically grounded structures and functional dynamics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomimetics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
