An ideal head-mounted display (HMD) is a device that provides a visual experience indistinguishable from that given by the naked eye. Such an HMD must display images with spatial resolution surpassing that of the human visual system. However, ...

The limited bandwidth of Wi-Fi severely confines the granularity (especially in differentiating multiple subjects) of Wi-Fi sensing, posing a significant challenge for its wide adoption. Though utilizing multiple channels to expand the effective ...

Cerebral examination via CTA is always the first choice for patients with unexpected brain injury or different types of brain lesions to detect ruptured hemangiomas, vascular infarcts, or other brain tissue lesions.

This study ...

Pan-sharpening is used to fuse multispectral images with low spatial resolution and a panchromatic (Pan) image with high spatial resolution to generate synthesized images featured with high spatial and multispectral properties. The pan-sharpened images ...

Hyperspectral imaging systems provide dense spectral information on the scene under investigation by collecting data from a high number of contiguous bands of the electromagnetic spectrum. The low spatial resolutions of these sensors frequently give rise ...

A sign language recognition system facilitates communication between the deaf community and the hearing majority. This paper proposes a novel specialised convolutional neural network (CNN) model, SignNet, to recognise hand gesture signs by incorporating ...

Recently, progress on semantic image segmentation is substantial, benefiting from the rapid development of Convolutional Neural Networks. Semantic image segmentation approaches proposed lately have been mostly based on Fully convolutional Networks (FCNs)...

Extracting the three-dimensional (3D) information including location and height of a pedestrian is important for vision-based intelligent traffic monitoring systems. This paper tackles the relationship between pixels′ actual size and pixels′ ...

The paper considers the use of supercomputers in design of medical ultrasound tomography devices. The mathematical models describing the wave propagation in ultrasound tomography should take into account such physical phenomena as diffraction, ...

Hyperspectral imaging makes it possible to obtain object information with fine spectral resolution as well as spatial resolution, which is beneficial to a wide array of applications. However, there is a high correlation among the bands in a hyperspectral ...

Dynamic Frame Rate (DFR) is the change in frame rate of a movie sequence in real time as the sequence is playing. Throughout the majority of the past century and after the introduction of sound in films, frame rates used in films have been kept at a ...

A fast macro block mode decision scheme is proposed in this work for arbitrary downsizing video transcoder based on H.264/AVC. For macro block to be re-encoded in downsized frame, the corresponding area in the pre-encoded frame is not aligned with the ...

We describe a method for the automatic recognition of air pollution and fog from a vehicle. Our system consists of sensors to acquire main data from cameras as well as from Light Detection and Recognition (LIDAR) instruments. We discuss how this data ...

We describe a method for the automatic recognition of weather conditions from a moving car. Our system consists of sensors to acquire data from cameras as well as from Light Detection and Recognition (LIDAR) instruments. We discuss how this data can be ...

We developed a focusing imager with a toroidally bent crystal imager. The imager can be used in X-ray imaging of laser fusion experiments. This article discusses the focusing properties of toroidally bent crystal in Bragg geometry. Simulations of ...

Video and image quality are often objectively measured using peak signal-to-noise ratio (PSNR), but for sign language video, human comprehension is most important. Yet the relationship of human comprehension to PSNR has not been studied. In this survey, ...

Hyperspectral imaging is a promising tool for applications in geosensing, cultural heritage and beyond. However, compared to current RGB cameras, existing hyperspectral cameras are severely limited in spatial resolution. In this paper, we introduce a ...

We present a new approach to capture video at high spatial and spectral resolutions using a hybrid camera system. Composed of an RGB video camera, a grayscale video camera and several optical elements, the hybrid camera system simultaneously records two ...

This paper describes a novel video coding scheme based on spatial resolution regulation. By comparing the R-D performance of spatially down-sampling coding scheme with standard coding schemes, the proposed coding scheme begins with coding the low-...

One of the main methods of determining the Earth structure is the analysis of the seismic data. Based on the seismic data, we produce a 3-D map describing the density at different locations on different depths. Due to incomplete coverage and measurement ...
