Person-Centered Multimedia Computing: A New Paradigm Inspired by Assistive and Rehabilitative Applications

Dr. Sethuraman Panchanathan

Abstract: Human-centered multimedia computing (HCMC) focuses on a tight engagement of humans in the design, development and deployment of multimedia solutions. Today’s multimedia technologies largely cater to the needs of the “able” population, resulting in HCMC solutions that mostly meet the needs of that community. However, individuals with disabilities have specific requirements that necessitate a personalized, adaptive approach toward smart multimedia computing. In addition, individuals with disabilities have largely been absent in the design process, and have to adapt themselves (often unsuccessfully) to available solutions. To address this challenge, we recently introduced the concept of person-centered multimedia computing (PCMC), where the emphasis is on understanding the individual user’s needs, expectations and adaptations towards designing, developing and deploying effective and smart multimedia solutions. In this talk, PCMC will be discussed from two application viewpoints: (i) social assistive aids to enrich the interaction experience of individuals with visual impairments and (ii) cyber-physical systems for stroke rehabilitation. Both these applications embody person-centeredness as the underlying methodology. Our research not only demonstrates the significant potential in using person centered multimedia solutions to enrich the lives of individuals with disabilities, but also the criticality of using a person centered approach to effectively address complex smart multimedia challenges in designing real-world solutions.

Towards Smart Signal Processing in HDR Video Pipeline

Guan-Ming Su, Dolby Labs, USA

Abstract: With the advancement of hardware technologies, such as camera and display, we have arrived at High Dynamic Range (HDR) video era. HDR related devices and content are already available to purchase and subscribe in the current market. On the other hand, HDR video exhibits different characteristics from conventional video owing to covering wide range of luminance and needs smart signal processing to fully utilize the pipeline for optimal perceptual performance. In this talk, we tackle several issues along the HDR video pipeline. More specifically, we will first discuss the HDR signal format, and point out the major difference and challenges from conventional video. Then, at the content processing stage, we present an efficient technique to transfer the image statistics to reuse the current legacy pipeline. At the content distribution stage, we address how to transmit a single bitstream to support different capability of display in a progressive manner.
