Getting Started with OpenCV provides an overview of OpenCV and demonstrates a basic OpenCV program. It discusses OpenCV's structure, loading and saving images, creating windows and trackbars, and using OpenCV with Intel's Integrated Performance Primitives for accelerated computer vision functions. The document contains code samples and explains how to compile, build, and run OpenCV programs on Windows and Linux.
Motion Capture is most widely used in entertainment, sports, medical applications and computer vision validation. In some fields, it is referred to as motion tracking, but in games and filmmaking, it is called matchmaking. There are many advantages and disadvantages of motion capture.

Eye Movement based Human Computer Interaction TechniqueJobin George
Eye movement-based interaction is one of several areas of current research in human computer interaction in which a new interface style seems to be emerging. In the non-command style, the computer passively monitors the user and responds as appropriate, rather than waiting for the user to issue specific commands. In describing eye movement-based human-computer interaction we can see two distinctions, one is in the nature of the user’s eye movements and the other, in the nature of the responses. In the world created by an eye movement based interface, users could move their eyes to scan the scene, just as they would a real world scene, unaffected by the presence of eye tracking equipment movement, on the eye movement axis. The alternative is to instruct users of the eye movement based interface to move their eyes in particular ways. On the response axis, objects could respond to a user’s eye movements in a natural way that is, the object responds to the user’s looking in the same way real objects do. The alternative is unnatural response, where objects respond in ways not experienced in the real world.
Now a days Eye tracking technology is applied in many fields like automotive defense and medical industries. The fields of advertising, entertainment, packaging and web design have all benefited significantly from studying the visual behavior of the consumer. Every day, as eye tracking is used in creative new ways, the list of applications grows.

PVS-Studio and Continuous Integration: TeamCity. Analysis of the Open RollerC...Andrey Karpov
One of the most relevant scenarios for using the PVS-Studio analyzer is its integration into CI systems. Even though a project analysis by PVS-Studio can already be embedded with just a few commands into almost any continuous integration system, we continue to make this process even more convenient. PVS-Studio now supports converting the analyzer output to the TeamCity format-TeamCity Inspections Type. Let's see how it works.
JVM Mechanics: When Does the JVM JIT & Deoptimize?Doug Hawkins
HotSpot promises to do the "right" thing for us by identifying our hot code and compiling "just-in-time", but how does HotSpot make those decisions?
This presentation aims to detail how HotSpot makes those decisions and how it corrects its mistakes through a series of demos that you run yourself.

Forge - DevCon 2016: Visual Reporting with Connected Design DataAutodesk
Viewing a 3D model on a webpage or in a mobile app is really cool, but visualizing design data isn’t just about meshes and textures. In this class Philippe Leefsma of Autodesk will show you how the Forge Model Derivative API and JavaScript viewer give you access to the valuable data associated with each model component that is extracted from the original design file. We will take that a step further and connect those models to an external database to add even richer data. Finally, we will stylize the model to turn a model into a powerful, intuitive reporting tool.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
