Object Tracking with Improved Detector of Objects Similar to Target

In paper, particle at the frame $t$ is represented by: $$c^{(i)}_t(i=1,\ldots, N)$$ and after that say let $c^{(i)}_t$ used by the proposed method be defined as

$$(x^{(i)}_t, y^{(i)}_t, u^{(i)}_t, v^{(i)}_t, w^{(i)}_t, h^{(i)}_t)$$

where $(x^{(i)}_t, y^{(i)}_t)$ represents the center position of the target object, $(u^{(i)}_t, v^{(i)}_t)$ represents the velocity of it and $(w^{(i)}_t, h^{(i)}_t)$ represent the width and the height of the rectangle which involves the target object.

I can't understand if $c^{(i)}_t$ is particle and a particle is a pixel. How a particle in Particle Filter can have width and height?

How to set $x$,$y$ of the target for a particle?
