The tutorial will take a holistic view on the ongoing research, the relevant issues, and the potential application of using synthetic data for multimedia data processing, as a standalone resource or in combination with real data. In particular, the attention will be focused on the domain of images and videos, where the lack of representative data for specific problem categories has let emerge the possibility of relying on machine-generated contents.

Image and video processing has seen a rapid growing in the last decade, with remarkable improvements made possible thanks to the availability of ever-increasing computing power as well as deep learning-based frameworks that now allow human-like and beyond performances in many applications, including detection, classification, segmentation, to name a few.

However, it is to be noted that the development of novel algorithms and solutions is strictly bound to the availability of a relevant amount of data, which must be representative of the task that needs to be addressed.

With this respect, the literature has shown a rapid proliferation of datasets, tackling a multitude of problems, from the simplest to the most complex ones. Some of them are largely adopted and are currently recognized as the reference benchmark against which all newly proposed methods need to compete. As far as images are concerned, the most famous ones are (in order of complexity) MNIST, CIFAR-10, CIFAR-100, ImageNet.

When dealing with videos, instead, action/event recognition is among the earliest tasks being addressed by the research community, and the most widespread and well-known datasets include the Weizmann dataset (for simple action recognition), the UCF-101, UCF-Sports, EgoKitchen, to name a few. In the domain of surveillance the CAVIAR, and the PETS datasets have been largely adopted and, more recently the MoT Challenge has attracted the attention of many researchers because of the variety and diversity of contexts and situations in which detection and tracking solutions can be validated.

Still, there is an ever growing demand for data, to which researchers respond with larger and larger datasets, at a huge cost in terms of acquisition, storage, and annotation of images and clips. However, when dealing with complex problems, it is common to validate the developed algorithms across different datasets, facing inconsistencies in annotations (i.e. segmentation maps vs bounding boxes), the use of different standards (i.e. the number of joints of human skeletons in OpenPose and SMPL).

The use of synthetically-generated data can overcome such limitations, as the generation engine can be designed to fulfill an arbitrary number of requirements, all at the same time. For example, the same bounding box can hold for multiple viewpoints of the same object/scene; the 3D position of the object is always known, as well as its volume, the appearance, and the motion features. These considerations have motivated the adoption of computer-generated content to satisfy mostly two requirements: (a) the visual fidelity and (b) the behavioral fidelity.

To this aim, researchers have investigated efficient solutions to cope with these problems, including fine tuning and domain adaptation.

The tutorial will cover a number of topics dealing with the current use of datasets in a topic-wise fashion, together with the corresponding methodologies in the state of the art. A tentative list of of the topics is reported hereafter:

  • image-based datasets and complexity
  • video-based datasets and complexity
  • limitations and need for adaptation
  • synthetic datasets, pros and cons
  • complementing real data with synthetic datasets
  • fine tuning, domain adaptation, unsupervised learning

The focus of the tutorial will be technical, we aim at giving participants a broad view of research and important topics for developing efficient algorithms and solutions that are capable of combining the use of real and synthetic data to solve complex problems.

Material Provided

The attendees will be provided with the presentation slides, together with a comprehensive list of papers and reports of interest, aimed on the one hand at letting attendees be acquainted with the topic, and on the other hand to promote the research in this interesting interdisciplinary area.

In this tutorial, we motivate, analyze and apply gradients of neural networks as features to understand image data. Traditionally, gradients are utilized as a computationally effective methodology to learn billions of parameters in large scale neural networks. Recently, gradients in neural networks have shown applicability in understanding and evaluating trained networks. For example, while gradients with respect to network parameters are used for learning image semantics, gradients with respect to input images are used to break the network parameters by creating adversarial data. Similarly, gradients with respect to logits provide predictive explanations while gradients with respect to loss function provide contrastive explanations. We hypothesize that once a neural network is trained, it acts as a knowledge base through which different types of gradients can be used to traverse adversarial, contrastive, explanatory, counterfactual representation spaces. Several image understanding and robustness applications including anomaly, novelty, adversarial, and out-of-distribution image detection, and noise recognition experiments among others use multiple types of gradients as features. In this tutorial, we examine the types, visual meanings, and interpretations of gradients along with their applicability in multiple applications.

The tutorial is composed of four major parts. Part 1 discusses the different interpretations of gradients extracted from trained neural networks with respect to input data, loss, and logits. Part 2 covers in detail a theoretical analysis of gradients. Part 3 describes the utility of gradient types in robustness applications of detection, recognition and explanations. Newer and emerging fields like machine teaching and active learning will be discussed with methodologies that use gradients. Part 4 connects the human visual perception with machine perception. Specifically, we discuss the expectancy-mismatch principle in neuroscience and empirically discuss this principle with respect to gradients. Results from Image Quality Assessment and Human Visual Saliency will be discussed to demonstrate the value of gradient-based methods. The outline as well as the expected time for each part is presented below.

In this tutorial, we introduce how the High Dynamic Range (HDR) imaging field has evolved in this new era where machine learning approaches have become dominant. The main reason for this success is that the use of machine learning and deep learning has automatized many tedious tasks achieving high-quality results overperforming classic methods.

After an introduction to classic HDR imaging and its open problem, we will summarize the main approaches for merging of multiple exposures, single image reconstructions or inverse tone mapping, tone mapping, and display visualization.

HTTP adaptive streaming is a complex technology with dynamics that need to be studied thoroughly. The experience from the deployments in the last 10+ years suggests that streaming clients typically operate in an unfettered greedy mode and they are not necessarily designed to behave well in environments where other clients exist or network conditions can change dramatically. This largely stems from the fact that clients make only indirect observations at the application (HTTP) layer (and limitedly at the transport layer, if any at all).

Typically, there are three primary camps when it comes to scaling and improving streaming systems: (𝑖) servers control client’s behavior/actions and the network uses appropriate QoS, (𝑖𝑖) servers and clients cooperate with each other and/or the network, or (𝑖𝑖𝑖) clients stay in control and no cooperation with the servers or network is needed as long as there is enough capacity in the network (said differently, use dumb servers and network and throw more bandwidth at the problem). Intuitively, using hints should improve streaming since it helps the clients and servers take more appropriate actions. The improvement could be in terms of better viewer experience and supporting more viewers for the given amount of network resources, or the added capability to explicitly support controlled unfairness (as opposed to bitrate fairness) based on features such as content type, viewer profile and display characteristics.

In this tutorial, we will examine the progress made in this area over the last several years, primarily focusing on the MPEG’s Server and Network Assisted DASH (SAND) and CTA’s Common Media Client/Server Data standards. We will also describe possible application scenarios and present an open-source sample implementation for the attendees to explore this topic further in their own, practical environments.


Upon attending this tutorial, the participants will have an overview and understanding of the following topics:

  • Brief review of history of streaming, key problems and innovations
  • Current standards, interoperability guidelines and deployment workflows
  • Focus topics
    • End-to-end system modeling and analysis
    • Improvements in player algorithms
    • Low-latency and omnidirectional streaming extensions
