ICMR

Welcome to the 5th ACM International Conference on Multimedia Retrieval, ICMR 2015. ICMR is a premier conference in the area of multimedia retrieval, offering great opportunities for exchanging leading-edge multimedia retrieval ideas among researchers, practitioners and other potential users of multimedia retrieval systems. Multimedia computing, indexing and retrieval continues to be one of the most exciting and fastest-growing research areas in the field of multimedia technology. However, opportunities for the exchange of ideas among different groups of researchers, and between researchers and potential users of multimedia retrieval systems, are still limited. The conference, which puts together the long-lasting experience of former ACM CIVR and ACM MIR series, was initialized in 2011 to illuminate the state of the art in multimedia retrieval.

This year we received a record-high number of 244 submissions to the main conference from 35 countries. After a rigorous review process by the program committee members, 113 papers from 23 countries were accepted for presentation. Conflict-of-interest papers authored by the program chairs were handled separately by the general chairs, and those from the general chairs were handled by the program chairs.

In addition, 12 borderline full papers were recommended to be downgraded to short papers, so the total number of accepted short papers is 46. We also moved 3 accepted special session papers to the regular sessions due to the cancellation of two planned special sessions, leading to a total number of n51 full papers in the regular program. The remaining 7 special session papers are presented in one special oral session and one special poster session.

The program also includes two tutorials and one workshop:

• Tutorial on "Social Multimedia Computing."

• Tutorial on "Multimedia Quality Modeling: Theories and Applications."

• Workshop on "Environmental Multimedia Retrieval."
