🔽 Simulator EP02_02: Spatial Image Subsampling
p'(i, j) = p(i·f, j·f)
Adjust the subsampling factor (f) to observe the reduction in the spatial dimension of the matrix and the skip-sampling of the top-left pixels of each f × f block.
1
f = 1 → Original Resolution (4×4) | f = 2 → Half (2×2) | f = 3 or 4 → Single Sample (1×1)
Original (4×4)
Subsampled (Variable Size)
Factor f = 1 → keeps all original pixels (4×4)
