A vast amount of multimedia data is becoming accessible, making the understanding of spatial and/or temporal phenomena crucial for many applications. This necessitates the utilization of techniques in the processing, analysis, search, mining, and management of multimedia data. The 8th IEEE International Conference on Multimedia Information Processing and Retrieval (IEEE-MIPR 2025) will take place in San Jose, CA, USA, on August 6–8, 2025, to provide a forum for original research contributions and practical system design, implementation, and applications of multimedia information processing and retrieval. The target audiences include university researchers, scientists, industry professionals, software engineers, and graduate students. The event includes a main conference as well as multiple associated keynote speeches, workshops, challenge contests, tutorials, and panels.
