Decimate

Decimate[img] returns a 2 × 2 × ... minimization of img using linear smoothing.

Decimate[img, k] returns a k × k × ... minimization of img using linear smoothing.

Decimate[img, {k₁, k₂, ...}] returns a k₁ × k₂ × ... minimization of img using linear smoothing.

Decimate[img, h, k] returns a k × k × ... minimization of img using smoothing filter h.

Decimate[img, {h₁, h₂, ...}, {k₁, k₂, ...}] returns a k₁ × k₂ × ... minimization of img using smoothing filters {h₁, h₂, ...}.

Decimate changes array dimensions by integer factor k.

Decimate[img], Decimate[img, 2], and Decimate[img, {0.25}, 2] are equivalent.

The argument img may be an array of any dimensions or ImageData expression.
