Multimedia Evaluation Benchmark MediaEval2025 https://lnkd.in/dam7CQrC -- The MediaEval Multimedia Evaluation benchmark offers innovative challenges that are of interests to researchers in the areas of , , , , . Registration is now open and submissions will be in October.

This year’s tasks are:
- : VQA (with multimodal explanations) for gastrointestinal imaging
- : Predicting movie and commercial memorability
- : Multimodal summarization of multiple topically related websites
- : Retrieval and generative AI for news thumbnails
- : Advancing detection of generative AI used in real-world online images

MediaEval places special emphasis on gaining insight into data and algorithms and moving forward the state of the art on tasks that are novel or unexpectedly challenging, due to the nature of the data or to a limited quantity of labels. The overall mission of MediaEval is to support that makes multimedia a positive force for society.

Results are presented at the next edition of the yearly MediaEval workshop, which will take place in Dublin, Ireland, Sat.-Sun. 25-26 October 2025, between CBMI 2025 (the 22th Content-Based Multimedia Indexing) and ACM Multimedia 2025 (the 33rd ACM International Conference on Multimedia). The workshop will provide an opportunity for online participation.

Check out our latest results in generating medical images via a latent-to-image approach in conditional . Apart from the high quality of the results, i.e., doctors cannot differentiate the generated vs real images, our approach ensures -preserving capabilities, i.e., synthetic medical images tend to contain traces of the original real training images, which may lead to revealing the identity of the source – see A.-G. Andrei, M.G. Constantin, M. Graziani, H. Müller, B. Ionescu, “Privacy Preserving Histopathological Image Augmentation with Conditional Generative Adversarial Networks”, Pattern Recognition Letters, Impact Factor 3.9, 2025 https://lnkd.in/dzurYV69 Universitatea POLITEHNICA din București HES-SO Valais-Wallis.

Congratulations to Alexandru Ioniță for winning the 2x 1st place (both in individual and team participation 😃) at the IBM Quantum: Qiskit Fall Fest https://lnkd.in/gdakvYuZ which was organized with the Military Technical Academy "Ferdinand I" -- Qiskit Fall Fest is a collection of events that invites students, researchers and industry professionals around the world to participate in a wide array of quantum-themed activities, ranging from quantum challenges, hackathons, and coding competitions to workshops, social events, and more. PS: Alexandru is developing his PhD thesis on quantum Artificial Intelligence. Keep up the great work! Universitatea POLITEHNICA din București

our special issue on Realistic Data: , , organized with ACM Transactions on Multimedia Computing, Communications and Applications, guest editors Bogdan Ionescu, Ioannis Patras, Henning Müller, Alberto Del Bimbo, is now online https://lnkd.in/dDtWR9Es – it is a timely collection of contributions targeting the various facets and modalities, e.g., signals, images, volumes, audio, etc., of the current trends in generating synthetic data, i.e., data which looks as real as it gets but it is computer generated. We received a record number of 40 submissions out of which 15 were finally accepted for publication. Enjoy your reading!

Check out our latest release on generating of flow-based – this is a COVID pandemic triggered application, i.e., helping to optimize and test network traffic via data that replicate very closely the actual behavior of home/office users, e.g., using software tools, social media, file transfer and so on. We also tested the data generator in augmenting data for traditional machine learning applications and successfully boosted . The data and code are – see Mihai Gabriel Constantin et al., “Exploring Generative Adversarial Networks for Augmenting Network Intrusion Detection Tasks”, ACM Transactions on Multimedia Computing, Communications and Applications, Impact Factor 5.2, Q1, https://dl.acm.org/doi/10.1145/3689636 – this is the outcome of a wonderful cooperation and industry project with Keysight Technologies Romania & USA Universitatea POLITEHNICA din București.
