We present a novel formulation of video stabilization in the space of geometric transformations. With the setting of the Riemannian metric, the optimized smooth path is cast as the geodesics on the Lie group embedded in transformation space. While solving the geodesics has a closed-form expression in a certain space, path smoothing can be easily implemented by using geometric interpolation, rather than optimizing any space-time energy function. Specially, by using the geodesic solution in the space of rigid transformations, our approach even gains speedup 10 faster than state-of-the-art methods for path smoothing and motion compensation, and guarantees no extra distortion drawn into the stabilized frames. The experiments demonstrate the efficiency and effectiveness of our algorithm on stabilizing a variety of shaky videos.

We present a system for converting a fully panoramic (360[Formula: see text]) video into a normal field-of-view (NFOV) hyperlapse for an optimal viewing experience. Our system exploits visual saliency...
The change detection in heterogeneous remote sensing images remains an important and open problem for damage assessment. We propose a new change detection method for heterogeneous images (i.e., SAR an...
Stitching videos captured by hand-held mobile cameras can essentially enhance entertainment experience of ordinary users. However, such videos usually contain heavy shakiness and large parallax, which...
The enthalpy and activation energy for the transformation of the metastable form of tungsten, β-W, which has the topologically close-packed A15 structure (space group Pm3¯n), to equilibrium α-W, wh...
Many studies are currently researching the effects of video games, particularly in the domain of cognitive training. Great variability exists among video games however, and few studies have attempted ...
The deficit of awareness of pathology (or insight) is a common symptom in patients with schizophrenia and has a negative impact on the prognosis of the disease. Current treatments aren't e...
Background: There is no evidence that shoulder stabilization effectively corrects the glenohumeral translation in unstable shoulders, explaining residual apprehension in certain patients. ...
Corroboratory behavioral evidence showed interaction effects between vestibular stimulation and egocentric transformation. The investigators here examine in healthy participants, whether ...
This is a prospective randomized clinical study to be performed in adult patients ages 18 and older who are undergoing surgical procedures requiring endotracheal intubation. Adult patients...
The purpose of this pilot study was to conduct a head-to-head comparison of two designs for transhumeral level upper limb prosthetic sockets: a traditional socket design and a socket desig...
Used with articles which include video files or clips, or for articles which are entirely video.
Endoscopic surgical procedures performed with visualization via video transmission. When real-time video is combined interactively with prior CT scans or MRI images, this is called image-guided surgery (see SURGERY, COMPUTER-ASSISTED).
A form of interactive entertainment in which the player controls electronically generated images that appear on a video display screen. This includes video games played in the home on special machines or home computers, and those played in arcades. (McGraw Hill Encyclopedia of Science & Technology, 7th ed, v19, p223)
Endoscopic surgery of the pleural cavity performed with visualization via video transmission.
The storing or preserving of video signals for television to be played back later via a transmitter or receiver. Recordings may be made on magnetic tape or discs (VIDEODISC RECORDING).
Standard antiretroviral therapy (ART) consists of the combination of at least three antiretroviral (ARV) drugs to maximally suppress the HIV virus and stop the progression of HIV disease. Huge reductions have been seen in rates of death and suffering whe...
