This paper describes the participation of our team-MIAR ICT in the ImageCLEF 2013 Robot Vision Challenge. The task of the Challenge asked participants to classify imaged indoor scenes and recognize the predefined objects appeared in the imaged scene. Our approach is based on the recently proposed Kernel Descriptors framework, which is an effective(More)
Food-related photos have become increasingly popular, due to social networks, food recommendation and dietary assessment systems. Reliable annotation is essential in those systems, but unconstrained automatic food recognition is still not accurate enough.

Contextual knowledge is crucial to improve recognition in such scenario. In particular, geocontext has been widely(More)
The phenomenal growth of the usage of mobile devices (e.g., mobile phones and tablet PCs) opens up a new service, namely mobile visual recognition, which has been widely used in many areas, such as mobile shopping and augmented reality. The rich contextual information (e.g., location, time and direction information), easily acquired by the mobile devices,(More)
