Advancement in image/video processing enables many novel applications that improve our daily life, such as immersive and interactive teleconferencing and smart mobile health monitoring. Immersion is a highly desirable characteristic in audio-visual conferencing, with potential to revolutionize long-distance healthcare and education.  However, such capability is currently associated with high-cost and limited accessibility.  In the first part of the talk, I will present a coherent suite of technology, including video analysis and processing as well as human computer interaction that may eventually allow one to experience telepresence using smartphones anywhere with access to the Internet.

As an early exploration of mobile health monitoring, I will present a method for dietary assessment in the second part of the talk.  Measuring accurate dietary intake is an open research problem in the nutrition and health fields.  Our method is capable of automatically identifying and locating food in a variety of images captured during controlled and natural eating events.  Two concepts are combined to achieve this: a set of segmented objects can be partitioned into perceptually similar object classes based on global and local features; and perceptually similar object classes can be used to assess the accuracy of image segmentation.  Improved accuracy of segmenting food images with classifier feedback is achieved.  Finally, I will discuss future developments targeting remote healthcare and long-distance learning.
