In terms of object recognition, the simplest patterns of lines are gratings, which can vary in two dimensions Frequency and contrast
<h3>
What is Frequency?</h3>
- The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively.
- One (event) per second is equal to one hertz (Hz), which is how frequency is stated. The period is the reciprocal of the frequency since it is the length of time for one cycle in a repeating occurrence.
- For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

Answer:

Stone polygons is the peri glacial landform feature results from the sorting of surface stones and soil particles into stripes or polygons.
The coordinates that make up a polygon region are determined by actual latitude and longitude values. A point (position) is the fundamental building block of a polygon, and you need at least three points to enclose a region in a polygon.
A peri glacial landform is a structure that is the product of strong frost, frequently in conjunction with perma frost. Periglacial landforms can only be found in regions with cold, essentially nonglacial conditions.
In the arctic and subarctic regions, rivers draining perma frost-covered basins release water and debr is into the sea, forming peri glacial-deltaic landscapes.
