The SSIM index is estimated locally over a 11 × 11 window, which moves pixel-by-pixel over the entire image.
It is a simple step that moves pixels taking them from one place in the original image and locating them in another position in a new rectified image.
Is the city-dweller best visualised as a smoothly moving pixel, travelling to work, shops and home again, on a colourful 3D graphic display?
(OULKBGII), occluded uncovered last known background ii,, (UBGII), uncovered background ii,, (MPII), moving pixel ii,, (PAPII), partially absorbed pixel ii,, (MPIII), moving pixel iii,.
The pixel belongs to the scene background, (1) (MP), moving pixel,.
Shade effect could label the pixel as a moving pixel and degrade the performance of algorithm.
They classified each moving pixel into the shadow or foreground object by performing a significance test.
A good way for discriminating between ambiguous situations is to return to moving pixel level.
We distort the image by moving pixel at (x, y) to (x, y′) using y′=y+f(x).
True positives (TP), false positives (FP), true negatives (TN) and false negatives (FN) are counted, considering a TP as a moving pixel which is inside the 2D image projection of the parallelepiped, a FP as a moving pixel outside the parallelepiped projection, a TN as a background pixel outside the parallelepiped projection and a FN as a background pixel inside the parallelepiped projection.
In order to do that, we added five more states to the FSM: (11) (OULKBGII), occluded uncovered last known background ii,, (12) (UBGII), uncovered background ii,, (13) (MPII), moving pixel ii,, (14) (PAPII), partially absorbed pixel ii,, (15) (MPIII), moving pixel iii,. .
