In this paper, we present two video processing techniques for contact-less estimation of the Respiratory Rate (RR) framed subjects. Due to modest extent movements related respiration in both infants and adults, specific algorithms efficiently detect breathing are needed. For reason, motion-related variations signals exploited identify monitored patient simultaneously estimate RR over time. Our ...

The goal of video motion magnification techniques is to magnify small motions in a reveal previously invisible or unseen movement. Its uses extend from bio-medical applications and deepfake detection structural modal analysis predictive maintenance. However, discerning noise complex task, especially when attempting very subtle, often sub-pixel As result, generally suffer noisy blurry outputs. T...

Electronic magnification of an image results in a decrease in its perceived contrast. The decrease in perceived contrast could be due to a perceived blur or to limited sampling of the range of contrasts in the original image. We measured the effect on perceived contrast of magnification in two contexts: either a small video was enlarged to fill a larger area, or a portion of a larger video was ...

Thispaper reviews computational techniques to efficiently represent, analyse and visualise both shortterm and long-term temporal variation in video and image sequences. This paper reveals temporal variation in videos that are imperceptible to the naked eye. The method takes a standard video sequence as an input, and applies spatial decomposition, followed by temporal filtering to the frames whi...

This paper proposes a novel approach to generate stereo video in which the zoom magnification is not constant. Although this has been achieved mechanically in a conventional way, it is necessary for this approach to develop a mechanically complex system for each stereo camera system. Instead of a mechanical solution, we employ an approach from the software side: by using a pair of zoomed and no...

We propose a video magnification method for magnifying subtle color and motion changes under the presence of non-meaningful background motions. use frequency variability to design filter that passes only meaningful removes ones; our obtains more impressive results without artifacts than compared methods.

Magnification is an effective aid for people with conditions causing resolution loss, but it inherently restricts the field of view. Therefore, magnification must be centered on the most important point of the scene. We determine this " point of regard " (POR) by recording eye movements of normal subjects while they watch video.

BACKGROUND Flexible video bronchoscopes, in particular the Olympus BF Type 3C160, are commonly used in pediatric respiratory medicine. There is no data on the magnification and distortion effects of these bronchoscopes yet important clinical decisions are made from the images. The aim of this study was to systematically describe the magnification and distortion of flexible bronchoscope images t...
