Metameric failure assessment and reduction between RGB and laser phosphor projectors

Stelios Ploumis, Ronan Boitard, Anders Ballestad, Gerwin Damberg, more

Journal of the Society for Information Display > 30 > 4 > 292 - 308

Metameric failure is commonly observed when different types of displays reproduce the same color, as it is defined by a colorimetry system, but the outputs do not match visually. Metameric failure is impacted by the used colorimetry system and the relation between the involved displays' spectral power distributions (SPDs). In this work, we assess the metameric failure between the upcoming types of...

36‐2: Invited Paper: Lasers, Lamps, or Phosphors – Choices for the Future of Digital Cinema

Michael Perkins, Alen Koebel

SID Symposium Digest of Technical Papers > 48 > 1 > 513 - 516

The first generation of digital‐cinema projectors has now been deployed into the majority of movie theaters around the world. The illumination technology used for that first generation was xenon lamps. When that choice was made xenon was the only viable technology that could achieve digital cinema’s goals. Today, cinema has a new set of challenges and a new set of technologies to choose from...

Scalable Lossless High Definition Image Coding on Multicore Platforms

Shih-Wei Liao, Shih-Hao Hung, Chia-Heng Tu, Jen-Hao Chen

Lecture Notes in Computer Science > Embedded and Ubiquitous Computing > Embedded Software Designs > 742-753

With the advent of multicores in all processor segments including mobile, embedded, desktop and server ones, we are in the new era of multiplying computing power via scaling the number of cores. The multicore approach is more versatile and programmable than the ASIC approach. For instance, the same multicore product can be adapted to the ever-improving potpourri image processing standards. Developing...

Digital Characters Machine

Jaume Duran Castells, Sergi Villagrasa Falip

Communications in Computer and Information Science > Digital Information and Communication Technology and Its Applications > Special Session (Visual Interfaces and User Experience (VIUE 2011)) > 339-344

In this paper, we will focus on the study of digital characters and existing technologies of creation. The type of character is increasing and in the future, they may assume many main roles. Digital characters must overcome issues, as Uncanny Valley to ensure the viewer does not reject them because of their low credibility. This statement makes us challenge the need to work with metrics to measure...

Real-Time Digital Film Processing

Henning Sahlbach, Wolfram Putzke-Röming, Sean Whitty, Rolf Ernst

Lecture Notes in Electrical Engineering > Dynamic System Reconfiguration in Heterogeneous Platforms > The Applications > 185-193

Real-time post processing for digital cinema is an extremely challenging task, due to large resolutions and the resulting high data rates. Applications with these requirements are beyond the scope of standard DSP processors, and ASICs are not economically viable due to a small market volume. As an answer to these challenges, the MORPHEUS platform offers reconfigurable processing engines with mixed...

Contemporary French Documentary

Alison J. Murray Levine

A Companion to Contemporary French Cinema > 356 - 375

Documentary film has existed in France since the invention of cinema. Alternately portrayed as the poor cousin of fiction film, a handmaiden to authoritarian regimes, or an arid purveyor of information, the documentary form has had many detractors, but its defenders have been equally ardent. In the past two decades, French documentary film has experienced unprecedented growth and popularity. Established...

Moving Between Screens

Guillaume Soulez

A Companion to Contemporary French Cinema > 96 - 116

Relations between cinema and television in France in recent years have been closely tied to the development of each of these media in its own field. With successful blockbusters, the new digital era, and the Internet on one hand, and the development of private networks, aging audiences, and the success of new‐style American series on the other, film and television have been looking for ways of forming...

Chaiqian/Demolition: Reflections on Media Practice

J.P. Sniadecki

Visual Anthropology Review > 30 > 1 > 23 - 37

In 2008, I spent three weeks filming a demolition site in the center of Chengdu, the capital of China's Sichuan province. I collaborated with migrant workers, site managers, and city dwellers to produce the feature‐length film Chaiqian (Demolition), which offers a sensual and open‐ended portrait of migrant labor, urban space, and ephemerality. This essay presents a set of reflections on the production...

A Review of Watermarking Application in Digital Cinema for Piracy Deterrence

Nilesh Kumar Dubey, Shishir Kumar

2014 Fourth International Conference on Communication Systems and Network Technologies > 626 - 630

2014 International Conference on Communication Systems and Network Technologies (CSNT)

Many pirated digital movies by camcorder capture are found on the Internet or on the street market before their official release. During piracy of cinema footage, composite geometric distortions commonly occur due to the angle of the camcorder relative to the screen. There are various research has been done to utilize the geometric distortions that will be occur during piracy in theatre to estimate...

GPU-based JPEG2000 decoding scheme for digital cinema

Jeong-Woo Lee, Bumho Kim, Jungsoo Lee, Ki-Song Yoon

16th International Conference on Advanced Communication Technology > 601 - 604

2014 16th International Conference on Advanced Communication Technology (ICACT)

For the digital cinema system specification released by Digital Cinema Initiatives, it was decided to use 2K or 4K images encoded by the JPEG2000 standard. JPEG2000 provides high compression rates and error tolerance, but it is a burden for both encoding and decoding. To improve the decoding performance, a parallel computing architecture called CUDA has been receiving a lot of attention recently....

Interactive film within the paradigm of institutional cinema

Ryszard Kluszczyński

Art Inquiry. Recherches sur les arts > 2014 > XVI (XXV) > 127-136

In this article I am considering the situation of interactivity and interactive film in the institutional context of the cinema that is outlined by the rules of cinematographic industry. I draw attention to the fact that despite the ongoing digitalization in all cinematographic areas: production, distribution, presentation, and reception, interactivity is seen as a non-film feature and, as a consequence,...

Yasutaka Matsuo, Ryoki Takada, Shinya Iwasaki, Jiro Katto

2013 IEEE International Symposium on Multimedia > 279 - 282

2013 IEEE International Symposium on Multimedia (ISM)

We propose a novel image super-resolution method from digital cinema to 8K ultra high-definition television using registration of wavelet multi-scale components with affine transformation. The proposed method features that an original image is divided into signal and noise components by the wavelet soft-shrinkage with detection of white noise level. The signal component enhances resolution by registration...

Color Mismatch Compensation Method Based on a Physical Model

Quoc Bao Do, Azeddine Beghdadi, Marie Luong

IEEE Transactions on Circuits and Systems for Video Technology > 2013 > 23 > 2 > 244 - 257

A new method for detecting and correcting color-timing mismatch in digital film is proposed. This method is based on a physical model which accounts for the absorption of light by the different layers of the film. The whole process consists of five sequential stages: shot change detection, registration, degraded zone detection, and unreliable motion detection and correction. One of the main issues...
