The document discusses 8K imaging technology. It describes an 8K camera system that uses either a four-sensor imaging method or three 33-megapixel image sensors. The four-sensor method separates light into green, green, red, and blue signals captured by separate sensors, improving resolution and reducing costs compared to single large sensors. Potential applications of 8K technology include high-quality medical training materials, security monitoring with powerful image processing, and CAD projects requiring highly detailed 3D models.

In October 2017, ISO/IEC JCT1 SC29/WG11 MPEG and ITU-T SG16/Q6 VCEG have jointly published a Call for Proposals on Video Compression with Capability beyond HEVC and its current extensions. It is targeting at a new generation of video compression technology that has substantially higher compression capability than the existing HEVC standard. The responses to the call are evaluated in April 2018, forming the kick-off for a new standardization activity in the Joint Video Experts Team (JVET) of VCEG and MPEG, with a target of finalization by the end of the year 2020. Three categories of video are addressed: Standard dynamic range video (SDR), high dynamic range video (HDR), and 360° video. While SDR and HDR cover variants of conventional video to be displayed e.g. on a suitable TV screen at very high resolution (UHD), the 360° category targets at videos capturing a full-degree surround view of the scene. This enables an immersive video experience with the possibility to look around in the rendered scene, e.g. when viewed using a head-mounted display. This application triggers various technical challenges which need to be addressed in terms of compression, encoding, transport, and rendering. The talk summarizes the current state of the complete standardization project. Focussing on the SDR and 360° video categories, it highlights the development of selected coding tools compared to the state of the art. Representative examples of the new technological challenges as well as corresponding proposed solutions are presented.

This talk presents the approach Frostbite took to add support for HDR displays. It will summarize Frostbite's previous post processing pipeline and what the issues were. Attendees will learn the decisions made to fix these issues, improve the color grading workflow and support high quality HDR and SDR output. This session will detail the display mapping used to implement the"grade once, output many" approach to targeting any display and why an ad-hoc approach as opposed to filmic tone mapping was chosen. Frostbite retained 3D LUT-based grading flexibility and the accuracy differences of computing these in decorrelated color spaces will be shown. This session will also include the main issues found on early adopter games, differences between HDR standards, optimizations to achieve performance parity with the legacy path and why supporting HDR can also improve the SDR version.
Takeaway
Attendees will learn how and why Frostbite chose to support High Dynamic Range [HDR] displays. They will understand the issues faced and how these were resolved. This talk will be useful for those still to support HDR and provide discussion points for those who already do.
Intended Audience
The intended audience is primarily rendering engineers, technical artists and artists; specifically those who focus on grading and lighting and those interested in HDR displays. Ideally attendees will be familiar with color grading and tonemapping.

Dan Isaacs, Director of Smarter Connected Systems at Xilinx, and Robert Chappell, Founder of EyeTech Digital Systems, co-present the "Implementing Eye Tracking for Medical, Automotive and Headset Applications" tutorial at the May 2015 Embedded Vision Summit.
When humans communicate with each other, we get important cues from watching each other’s eyes. Similarly, machines can gain valuable information and new capabilities by detecting and tracking users’ gazes. Robust eye tracking was once limited to cumbersome laboratory set-ups, but today—thanks to improvements in sensors, processors and algorithms—eye tracking can be embedded into a wide range of products such as medical devices, industrial equipment, digital signage and cars. In these applications, eye tracking enables seamless augmented reality, natural user interfaces, and analysis of which objects and information are most interesting to users.
In this presentation, Dan and Robert present the design of a portable/wearable eye-tracking system. They introduce the fundamental techniques used for eye tracking. Then, they explore the challenges of implementing robust eye-tracking in a cost- and power-constrained system, and show an innovative design implemented on a programmable SoC that overcomes these challenges. They conclude with a live demo of the eye-tracking system.

Vieworks' TDI line scan cameras are based on new innovative “hybrid” sensor technology. The sensors combine CMOS and CCD. The base sensor has is a classic CMOS structure with much faster readout speeds and lower power consumption. However the sensors use CCD photo cells to capture the images and CCD technology still offers higher dynamic range and better image quality. In addition, the integration and transfer of stages is done by moving charge in CCDs, making this process virtually noiseless. The TDI line scan cameras based on these new hybrid imaging sensors allows image captures as fast as 250 kHz line rates with up to 256 stages. They are designed for applications where faster line rates and higher sensitivity are critical.
The TV market is moving rapidly towards high-definition television, HDTV. This change brings truly remarkable
improvements in image quality and color fidelity. HDTV provides up to five times higher resolution

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
