wiki_function/lossy-compression-algorithms7_53_0.txt | The image on the right in the top left quadrant has a compressed
representation of the full-scale image on the left, which can be reconstructed
from the smaller one by applying the wavelet coding transformation inversely.

wiki_function/compressing-floating-point-data4_33_0.txt | Reducing precision in a controlled way is "lossy compression." "Lossless"
means that compressing and then uncompressing yields exactly the same data,
bit-for-bit, as the original. If the result is only an approximation (usually
degraded in some controlled/bounded way), then that's "lossy compression."

An alternative method of lossy compression is wavelet transformation; which

a set of functions, called wavelets to transform to decompose an input signal. | |
