Spatial dependence

The spatial dependence property of pixels states that the meaning or interpretation of a single pixel in an image can often only be understood in the context of the pixels around it.

This is because the information in a single pixel is often not enough to describe the complete picture, or even just the pixel itself.

Hence, the relationship between the given pixel and its neighbouring pixel is necessary to provide a full understanding of this particular pixel, or even the image as a whole.
