    Enabling “Internet of Things” – A New Research Focus of MCLab

Enabling “Internet of Things” – A New Research Focus of MCLab

Professor C.-C. Jay Kuo announced a new research focus of MCLab on “Internet of Things (IOT)”. Professor Kuo said that the concept of IOT and some of its implementations had existed for years yet sparsely in isolated areas such as Fedex/UPS mailing systems, smart green building, smart home, etc. The connection between IOT and cloud/distributed computing platform and the emergence of wearable devices make an extensive IOT deployment a reality. Enabling technologies for IOT systems include: sensing (data acquisition), networking (data exchange/aggregation), computing (data analytics), storage (data preservation), control (decision making) and security/privacy of data and systems.

By leveraging on its core competence, MCLab will have emphasis on visual sensors acquired by video and depth cameras and conduct video analytics to recognize people, scene and environment and to understand human emotions, activities, behaviors. These techniques can be applied to effective learning, video surveillance, assistance to blind, automated driving, etc.

MCLab Releases the New Video Database: MCL-V

The high-definition video broadcasting and streaming services are blooming nowadays.  Consumers can enjoy on-demand video services from Netflix, Hulu or Amazon, and watching high-definition (HD) programs becomes the mainstream for video content consumption. According to the latest report, more than half of US population watches on-line movies or dramas. Specifically, the viewers have increased from 37% in 2010 to 51% in 2013. The watched video programs vary in bit rates and resolutions due to the available bandwidth of their networks. Different sizes of video are transmitted at lower bit rates and up-scaled for display on HDTV (e.g., playing a 720p movie on the 1080p screen). This is common in people’s daily life, yet video quality assessment on HD streaming video has not yet been extensively studied in the past.

To fulfill the need, MCLab has released a new video image database recently, which is called MCL-V. This database captures two typical video distortion types in video services. It contains 12 source video clips and 96 distorted video clips with subjective assessment scores.  The source video clips are selected from a large pool of public-domain HD video sequences with representative and diversified contents. Both distortion types are perceptually adjusted to yield distinguishable distortion levels. An improved pairwise comparison method is adopted for subjective evaluation. Furthermore, several existing image and video quality assessment algorithms are evaluated against MCL-V database.  MCL-V is publicly accessible to facilitate future video quality research of the community.

MCLab Releases the New 3D Database: MCL-3D

Stereoscopic image/video contents have become popular nowadays. Since the multi-view image format is costly for visual communication, the 2D-image-plus-depth format is proposed as an alternative, where a texture image and its associated depth image are recorded at a view point simultaneously. For stereoscopic display, the depth image-based rendering (DIBR) technique is applied to the texture and depth images to generate the proper left and right views.

One critical issue regarding 3D-related applications is to develop a robust metric to assess the quality of 3D image (or video) stimuli. Although a good stereoscopic image quality assessment is much in need due to the emergence of 3D visual contents, most of stereoscopic image databases are still small and based on traditional stereo image format, that is, captured left and right images. This restricts the design of good objective quality metrics.

To tackle these limitations and facilitate the related research, MCLab has released a new 3D image database recently, which is called MCL-3D. This database is valuable for the following reasons. Firstly, the MCL-3D database adopts the 2D-image-plus-depth source, where stereoscopic images are synthesized by the DIBR rendering technique. Secondly, all stereo images in the MCL-3D database are of high resolution, which is closer to today’s real world applications. Finally, the database is downloadable online with the detailed description of the database generation and the corresponding subjective test. We hope that our MCL-3D database can help other researchers in developing a good quality assessment metric.

MCLab Initiates Code Sharing Project

As algorithms become more and more complex, the implementations become more and more difficult. Without firsthand knowledge on the algorithm, it is extremely difficult and time consuming to build programs with respect to the publications. Many researchers are actively releasing their source code to the computer vision community these days. Their kindness gives great momentum to the development of better algorithms and the analysis on the existing approaches.

MCL wants to be a part of the selfless community by releasing all our research programs to the public. We are initiating the MCL Codebase Project, which aims at sharing our group member’s first hand implementations to the world. Since we are currently working on various researches, we will index them into five categories, including image/video quality assessment, face detection and recognition, scene recognition, object detection, image retrieval.

We will be offering projects through Github, so source codes are constantly updated and maintained. Anyone can easily branch either a stable version or a cutting edge development. The source code will be released under GNU General Public License, so researchers can use them freely. Researchers are welcome to contribute to our codebase. Send us a pull request and help us build a more powerful code base.

Our group member Hao Xu, Xiaqing Pan, and Chen Chen will serve as the MCL Codebase Project committee. Our senior group member Joe Lin, Sudeng Hu, and our group alumni Jiangyang Zhang will join the board of advisory. Professor Kuo will closely monitor the progress of this project.

    MCLab Inspires Cooperative Biomedical Research between USC and UCLA

MCLab Inspires Cooperative Biomedical Research between USC and UCLA

The Media Communication Lab (MCLab) at USC has a strong commitment to providing an interdisciplinary environment for student researchers, to nourish diversity of application of electrical engineering. Ph.D. candidate Xue Wang, whose research interest lies in biomedical and information processing, has been working on the validation of an evaluation tool for assessing surgical techniques. Capsulorhexis, which is a significant portion of cataract surgery, is of particular interest. Ongoing work on this problem has collaboration between faculty in the Ming Hsieh Department of Electrical Engineering at USC and the Jules Stein Eye Institute (JSEI) at UCLA since June of 2013.

The research aims at developing a valid set of quantitative and qualitative measures of surgical skills to accelerate the training of residents. Currently, capsulorhexis surgical techniques are assessed through an expert-panel-video-review using evaluation questions from the OSCAR and GRASIS evaluation tools.* However, there is considerable inter-observer variability, and direct quantitative questions were the least reliable. Xue’s work combines knowledge in biomedical image/video processing, machine learning, and computer vision to develop an automated quality assessment system to evaluate and improve surgical techniques, such that it is objective, accurate, and reliable. Human inspection is minimized along with the exploration of surgical video understanding via machine learning.

“It’s exciting to put focused and concerted effort in exploring the unknown and trying to find a solution for challenging problems. When you are working with excellent and talented people, you have a more open outlook on the potential of new cross-disciplinary methods”, Xue said. Xue’s work has been presented at AUPO and ASCRS conferences in January of 2014 and April of 2014, respectively.** Her result shows that video/image analysis provides an objective way to measure proficiency in the capsulorhexis part of cataract [...]
