Spatial Audio for Virtual and Augmented Reality Devices

Virtual and augmented reality devices are a hot topic for research and product development. In most of the cases these devices come in the form of head mounted displays. Integral part of these devices are several audio subsystems: spatial audio rendering, capture of the user’s voice and capturing the environmental audio.

Unlike the vision, where humans have approximately 90° field of view, human hearing covers all directions in all three dimensions. This means that the spatial audio system of these devices is expected to provide realistic rendering of sound objects in full 3D to complement the stereoscopic rendering of the visual objects.

In this tutorial, we will discuss the problems and potential solutions around the spatial audio subsystem in the devices for virtual and augmented reality. These include the Head-Related Transfer Functions (HRTFs) personalization, generation of the proper reverberation and distance cues. Most of the problems and solutions have broader scope and affect everyday scenarios such as listening to stereo music with headphones and watching movies on mobile devices.

Adaptive Streaming of Traditional and Omnidirectional Media

This tutorial consists of three main parts. In the first part, we provide a detailed overview of the HTML5 standard and show how it can be used for adaptive streaming deployments. In particular, we focus on the HTML5 video, media extensions, and multi-bitrate encoding, encapsulation and encryption workflows, and survey well-established streaming solutions. Furthermore, we present experiences from the existing deployments and the relevant de jure and de facto standards (DASH, HLS, CMAF) in this space. In the second part, we focus on omnidirectional (360°) media from creation to consumption. We survey means for the acquisition, projection, coding and packaging of omnidirectional media as well as delivery, decoding and rendering methods. Emerging standards and industry practices are covered as well. The last part presents some of the current research trends, open issues that need further exploration and investigation, and various efforts that are underway in the streaming industry.

Future Video Coding: Beyond H.265/HEVC

The H.265/HEVC standard is the latest video coding standard developed by the Joint Collaborative Team on Video Coding (JCT-VC), from both ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Pictures Expert Group (MPEG) in January, 2013. When compared to its predecessor, H.264/ AVC, H.265/HEVC achieves significant bit-rate saving due to new coding technologies. Since then, extensions from H.265/HEVC, such as range extensions, scalability, multi-view, 3D video coding, and screen content coding, has been made for further applications. In addition, new coding technologies are being developed through VCEG-KTA, VP10, AVS2, IEEE 1857, JVET, 360° Video Coding, etc. This tutorial will be focused on newly developed technologies from VCEG-KTA, VP10, AVS2, IEEE 1857, JVET, 360° Video Coding, as well as recent advances of perceptual video coding, besides H.265/HEVC video coding standard and its extensions: RExt (range extensions), SHVC (scalable extension), and MV-HEVC (multiview extension) SCC (Screen Content Coding extension).

Visual Content Perception and Understanding

Over the past decades, there has been a growing interest in visual content perception and understanding with broad multimedia applications. As an important component of visual perception, visual quality assessment has attracted extensive attention from both academia and industry. It can be used not only in monitoring image quality distortions, but also in optimizing various image processing algorithms/systems. Visual recognition aims to analyze visual content from images and videos, which plays an important role in many visual content understanding systems such as face recognition, person re-identification, and visual search. In this tutorial, we provide the past achievements, current status, and open problems of visual quality assessment and visual recognition.

Deep Learning for Big Visual Data Analytics

Deep learning has received a lot of attention in recent years due to its superior performance in many computer vision benchmarking datasets. In this course, I will cover the following four topics.

A. Big Visual Data Analytics

I will first discuss several basic concepts related to the big visual data analytics problem such as discriminative versus generative models, heavily versus weakly supervised learning, etc. to set up the modern data-driven machine learning methodology. I will also introduce several well-known datasets such as the ImageNet, the Places, the Microsoft CoCo datasets.

B. CNN Architectural Evolution

I will begin with the McClulloch and Pitts (M-P) neuron model and network in 1943, then the artificial neural network (ANN) in 80s and 90s, and finally the modern convolutional neural network (CNN) since late 90s. The differences between these three generations of networks will be clearly explained. Furthermore, there are three main types in modern CNNs: pyramidal CNNs, fully convolutional networks (FCN) and residual networks. Their specific functions are explained.

C. Theoretical Foundation

I will provide a theoretical foundation to the working principle of the CNN from a signal processing viewpoint. To begin with, the RECOS transform is introduced as a basic building block for CNNs. The term “RECOS” is an acronym for “REctified-COrrelations on a Sphere”. It consists of two main concepts: data clustering on a sphere and rectification. Then, a CNN is interpreted as a network that implements the guided multi-layer RECOS transform. Along this line, we first compare the traditional single-layer and modern multi-layer signal analysis approaches. Then, we discuss how guidance is provided by data labels through backpropagation in the training with an attempt to offer a smooth transition from weakly to heavily supervised learning.

D. Deep Features Visualization and Analysis

A deep network can learn features (called deep features) automatically from training data. I will use two quantitative metrics to shed lights on learned deep features. They are the Gaussian confusion measure (GCM) and the cluster purity measure (CPM). The GCM is used to identify the discriminative ability of an individual feature while the CPM is used to analyze the group discriminative ability of a set of deep features. It is confirmed by experiments that these two metrics accurately reflect the discriminative ability of trained deep features.
