This means that no more than one outlier, in average, is in the sliding data frame of size L = 5 during the robustified EPE calculation in (31) and MAD calculation in (9), respectively, when the fraction of outliers is 1%%.
The proposed method detects abrupt scene changes between adjacent frames by computing the proportion of invalid pixels with respect to the total number of pixels in the observed LR frame of size [M × N]: 1 M N ∑ k = 1 M N I ( d k ( t ) ) ≥ T h, w h e r e I ( d k ( t ) ) = 1 i f d k 2 ( t ) > γ. 0 o t h e r w i s e.

In the experiments, we take sample videos from the DynTex database that have a duration of 10 s (150 frames), with a frame size of 176×120 pixel size.
Additionally, the DSP algorithm can process up to 12 frames per sec for a frame of 480 × 720 pixels size in RGB format.
The processing times in Table 3 lead to a possible conclusion that the DSP algorithm can process up to 20 frames per sec for a frame of 240 × 360 pixels size in RGB format.
The video-frame-based PSNR is defined in (1), where a frame size of M × N pixels is assumed, and ( f i, j - f i,j ′ ) stands for the luminosity difference per pixel due to the video quality degradation.
In round two, R2 requires a frame size of two, and hence all readers use that frame size even though R1 had to read only one tag (R1 does not know that T4 has been put to sleep by R2).
In the first step, the incoming signal is split into small frames with a frame size of M samples and a hop size h which is the distance in samples between the starting points of subsequent frames.
1. Ramp up the resolution... or not Owners of an iPhone 6S or an iPhone 6S Plus can record video footage in glorious 4K (that's a frame size of 3,840 x 2,160 pixels), and it's also supported on some flagship Android phones.
