Judging from their physical characteristics, this deformation likely represents the trampling and churning of these sands by dinosaurs after their deposition.

From the standpoint of digital signal processing, the scaling of raster graphics is a two-dimensional example of sample-rate conversion, the conversion of a discrete signal from a sampling rate (in this case the local sampling rate) to another.

Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem.

According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts.

In the case of up sampling, a reconstruction filter takes the place of the anti-aliasing filter.

Sinc and Lanczos resampling .

Sinc resampling in theory provides the best possible reconstruction for a perfectly bandlimited signal.

In practice, the assumptions behind sinc resampling are not completely met by real-world digital images.

Lanczos resampling, an approximation to the sinc method, yields better results.

Bicubic interpolation can be regarded as a computationally efficient approximation to Lanczos resampling.

When down scaling below a certain threshold, such as more than twice for all bi-sampling algorithms, the algorithms will sample non-adjacent pixels, which results in both losing data, and causes rough results.

The trivial solution to this issue is box sampling, which is to consider the target pixel a box on the original image, and sample all pixels inside the box.

Another solution to the downscale problem of bi-sampling scaling are mipmaps.
