(d) Decoded OB 9th frame background (Object 2).
Frame-by-frame background subtraction was performed for each indicator as described above.
First, the original game design: the soundtrack, frames, background story, and the complexity of the gaming elements.
For each frame, background intensity was estimated at each pixel as the median intensity of the pixel over the entire video.
Emission data were then acquired over 60 min in list mode as 18 time-frames (one background frame of approximately 7 min prior to injection, followed by 17 frames: 1 × 15 s, 1 × 5 s, 1 × 10 s, 1 × 30 s, 4 × 60 s, 7 × 300 s and 2 × 600 s).
In the first experiment, we used the ASOD [34] dataset comprised of input frames, a background frame, and the corresponding ground truth (manually annotated and automatically generated inaccurate masks) of static foreground from PETS2006 [35] , PETS2007 [36] , AVSS2007 [27]CVSG [37], VISOR [38], CANDELA [39], and WCAM [40].
It has been framed against a background of mutual exasperation with Greece over its difficulties in policing its frontier with Turkey, an EU external border thought to be the main crossing point into the union for clandestine migrants.
Painted alternatively on plain white and black backgrounds, framed by exquisitely delicate trompe l'oeil decorative architecture, the landscapes, buildings, human and animal images are sketched with deft Impressionistic brush strokes in pastel colors, creating an almost dream-like effect.
The six models are classified into the frame-level models, that is, for I frames and for P frames, and region-level models, that is,,,,, which represent the models of ROI in the I-frame, the background in the I-frame, ROI in the P-frame, and the background in the P-frame, respectively.
Accompanied by a deep aroma, these satisfying flavors are neatly framed by a nonintrusive background of oak from the barrels, and buttressed by firm tannins.
