Light Field Transmission more_vert

Partners: Eduardo Peixoto, Edson Mintsu Hung, Bruno Macchiavello (UnB) and Gene Cheung (York University)

Light Field Transmission close

Light field (LF) imaging captures multiple intensities and directions of light per pixel during acquisition in a 3D scene, so that novel images of different viewpoints or focal points can be synthesized. However, transmitting all LF data before viewer observation incurs a large startup delay. To avoid such delay, we propose a new interactive LF streaming framework, where a client periodically requests viewpoint images, and in response a server synthesizes and transmits each requested image as a carefully chosen sparse linear combination of sub-aperture images. For each received synthesized image, the client “decodes” and recovers a new sub-aperture image using a cache of known sub-aperture images. As the cache of decoded sub-aperture images grows over time, the client becomes capable of synthesizing new view/focal point images, reducing overall transmission cost.

Point Cloud Compression close

Projeto de pesquisa e desenvolvimento em compressão de vídeo de ultra-alta-definição e processamento de nuvem de pontos dinâmicos

Point clouds are one of the most promising technologies for 3D content representation. Point clouds are a set of points described by their geometry information and additional attributes, of which colour is the most typical. When transmitting a point cloud, both geometry, colour and temporal information need to be transmitted, thus making compression efficiency key in exploiting this technology.

High Dynamic Range Imaging more_vert

High Dynamic Range Imaging close

Recently there has been a lot of interest in the development of High Dynamic Rage (HDR) imaging technology. One particular methodology that has attracted attention is the Multiple Exposure Fusion (MEF), which involve the image fusion based on exposure functions. This work implements and tests a simple, low-complexity, MEF algorithm, that is able to produce high contrast images.

All-In-Focus Imaging more_vert

Partners: Natália Teixeira, Ricardo Marra and Eduardo Peixoto (UnB)

All-In-Focus Imaging close

Focus stacking or all-in-focus imaging consists of merging several input images with a narrower depth of field into one output image with a wider depth of field. Here, an all-in-focus image is produced from a large sampled focal stack. Then, we use a post-capture algorithm to select which of the images in this focal stack are useful for a given scene. Results show that the proposed method is able to reduce artifacts in the image fusion algorithm, producing comparable results to a small-aperture capture, which naturally has a wider depth of field.

Research in Video Coding close

Improvement of wedge partition techniques used in VP10 Google’s Codec using a boundary based block partition

Video coding is, essentially, an enabling technology. The video data is not compressed for the sake of compression, it is compressed in order to transmit or store more content using the same resources. Most applications would not be feasible without video compression, as the amount of data required would be extremely high. In this project, we aim to improve the performance of motion estimation, an essential tool in all hybrid DPCM/DCT video codecs, by better adapting the prediction step of the codec. The developed algorithms will be implemented in Google's VP10 open source codec.

Fast Video Coding close

Development of Fast Algorithms for Video Coding in the HEVC Standard (Desenvolvimento de Métodos Rápidos para Codificação de Vídeo no novo padrão HEVC)

Digital video comsumption has grown exponentially in recent years. Today, we watch video content not only through television, but through the internet as well, whether using personal computers, tablets or mobile phones. At the same time, the quality of the consumed video has improved tremendously in this period - it is common nowadays to watch high resolution (HD) videos through online video streaming. However, transmitting higher quality videos require higher bandwidth. For this reason, the ITU-T and the ISO-IEC released, in 2013, a new video coding standard, so called High Efficiency Video Coding (HEVC). This new standard achieves the same video quality as its predecessor, the H.264/AVC, with only half of the bitrate. However, in order to achieve this efficiency, the new encoder needs much more computational power than the H.264/AVC. Therefore, the development of low complexity, fast encoding algorithms for the HEVC is a highly competitive field, with immediate application. This project focuses on the development of fast video coding algorithms for the HEVC, especially for high definition (1920 x 1080) and ultra-HD (4K, or 3840 x 2160) content.

Monitoring Heart Rate through Video more_vert

Participants: Otávio Dias, Maximillian Xavier, Eduardo Peixoto

Monitoring Heart Rate through Video close

Heart rate monitoring is an important tool in medicine. The most common methods for measuring the heart rate are the use of chest straps, adhesive electrodes or oximeter sensors. All these techniques require some sort of contact with the patient, which may be undesirable in some cases. The aquisition of this signal without physical contact with the patient is desirable as it simplifies some applications, such as neo-natal ICU, long term monitoring, sleep pattern studies, among others.

In the last decade it has been shown that images of the face of a patient contain sufficient data to measure some important biological signals, such as the heart rate and the arterial pressure. The first studies used thermal images to acquire these signals howeve, recently, some algorithms were shown to be able to gather this information using common video cameras in ambient light.

The main goal of this project is to develop and implement algorithms for heart rate monitoring using just the data from a simple webcam. This algorithm should work in real time, being able to film the face of a person and output an estimative for this person heart rate.

Research in Video Transcoding more_vert

Partners: Ricardo L. de Queiroz, Edson Mintsu Hung, Bruno Macchiavello, Alexandre Zaghetto, Filipe Teixeira

Research in Video Transcoding close

Recently, a new video coding standard has been ratified, so called High Efficiency Video Coding (HEVC). This new standard offers a much better performance compared to its predecessor, the H.264/AVC. The H.264/AVC standard is very successful and it has been widely adopted, both by physical media, internet streaming services and some broadcast and cable television services. Video transcoding is the process that converts from one compressed bitstream (called the source or incoming bitstream) to another compressed bitstream (called the transcoded or outgoing bitstream). The motivation for an H.264/AVC to HEVC transcoder is twofold: (i) to promote inter-operability for the legacy video encoded in H.264/AVC format; and (ii) to be able to take advantage of the superior RD performance of the HEVC, especially for systems that have extensive video libraries. This project focus on developing new algorithms for video transcoding, in particular from H.264/AVC to the current HEVC standard.

Study of Plenoptic Cameras more_vert

Participants: Bruno Pessoa Chaves, Eduardo Peixoto

Study of Plenoptic Cameras close

Conventional Cameras capture only the intensity of light in each point, losing the information about the direction of the incident light rays. Plenoptic cameras, also known as light field cameras, are able to capture not only the intensity, but the direction of the light rays, thus obtaining much more information about the scene than conventional cameras.

An important application for these cameras is the estimation of depth maps, i.e., a map of of the scene that estimates the distance from each object to the camera. These depth maps have broad applications, such as to add or remove blur in the images, as well as to make a 3D scene from the images.

The main goal of this project is to develop algorithms to estimate depth maps from data obtained from a Lytro camera, a low cost first generation plenoptic camera.

Thira - Research in Video Coding close

Enabling Technologies for High Resolution Content Exchange and Delivery (Thira)

THIRA is a collaborative project led by the BBC and co-funded by the Technology Strategy Board which addresses usage of larger resolution video formats. Recent advances in video capturing and display technologies provide audiences with higher spatial and temporal resolution content. After High Definition (HD), nowadays Ultra High Definition (UHD) aims to further improve users' quality-of-experience at the cost of increased storage capacity and bandwidth. Ultra high definition targets two formats with 16:9 aspect ratio: the first has twice the width of HD while the second has four times the width of HD. To properly handle the data rates associate to UHD content, the H.265/High Efficiency Video Coding (H.265/HEVC) standard will be mainly used. H.265/HEVC is the newly ratified video compression standard developed by both ITU VCEG and ISO/IEC MPEG in a joint partnership called the Joint Collaborative Team on Video Coding (JCT-VC). HEVC results from a joint VCEG and MPEG call for proposals on compression technology able to achieve the same perceived quality of the H.264/AVC standard by halving the required bitrate. The H.265/HEVC standard provides a base for handling ultra high resolution content. Underpinning the capabilities of HEVC are computationally expensive, extremely complex and resource demanding algorithms. Consequently, in its current state, H.265/HEVC is unfeasible for practical applications involving very high definition content. THIRA aims to facilitate storage and transmission of the huge amounts of data contained in very high resolution content using the H.265/HEVC standard.
