Fig. 6.31 An example of the position of the sample definition domain of a connected frame f with
maximum offset along X- and Y-axes [10]
function is determined by the parameter (number of iterations); the offset of the
definition domain from the zero position along the alignment direction is set as At,
across the alignment direction—as kτ ort .
The pixels along the vertical section are used as a sample. In this case, the generalized coordinate t coincides with the coordinate Y. Acquisition size N = LY − 2d,
where LY is the frame size by Y (height) in pixels; d is bounce.
After defining the sample f , the morphological correlation function of R m is calculated by software means; the first sample f 2 is taken from the middle of the domain
of its definition. After calculating the morphological correlation, its value is remembered. After that, the function f is shifted to the left and to the right relative to the
