This approach allows the flexibility to change the background image and/or
foreground icons independently.
In recent years, with the development of video technology, the research on the automatic
foreground extraction will become more and more popular.
where D is a data matrix whose columns are the pixels from each frame in the video sequence; L denotes a low-rank matrix which naturally corresponds to the stationary background; and S is a sparse matrix which contains the moving objects in the
foreground. The Frobenius norm [[parallel]*[parallel].sup.2.sub.F] is defined as the quadratic sum of the matrix elements; the nuclear norm [[parallel]*[parallel].sub.*] is defined as the sum of its singular values; the [l.sub.1]-norm [[parallel]*[parallel].sub.1] is seen as the sum of the absolute values of the matrix elements [18,19].
Background subtract [9] is a common method used in
foreground detection.
? Views of Eston, top left - a black and white postcard from the 1920s gives a view of Eston showing the chapel and the George IV public house; Top right - the chapel in the
foreground stood on the corner of Church Lane and the High Street; above - Eston Institute before the clock was installed; Right - Eston Nab and mines; Left - Christ Church when it was still surrounded by farmland
The Cosmic Eye is socalled because the
foreground galaxy, which is 2.2 billion light years from Earth, appears in the centre of an arc created by the distant galaxy - giving it the appearance of a human eye.
The
foreground galaxy, or lens, lies 3 billion light-years from Earth, while the inner and outer rings are images of galaxies that lie farther away--6 billion and 11 billion light-years--and hail from an earlier epoch of cosmic history.
The fiddle playing for a bluegrass song can be listened to with the same
foreground attention usually brought to the premiere of a new string quartet.
3 Figures are placed in the
foreground and work begins on constructing a hut.
In the
foreground of the picture is a sign or marker with Arabic writing on it that I think expresses an anti-American sentiment.
Foreground, used as a verb, is a favorite; something is
foregrounded almost every third page.
Start the 4.6-liter, 320-horse-power Northstar V-8 engine, and the XLR's Corvette heritage roars into the
foreground. Hit the button to retract the hardtop and put the XLR in gear--the purring engine howls and rockets you forward.
