LMMIP

A TECHNIQUE FOR IMAGE COMPRESSION WITH CONTROLLED MAXIMUM ERROR
Main idea: hierarchic image representation with use of a reconstructed data "feedback" that relies on pixel interpolation)

Original image:



Reconstruction error:

Standard JPEG method	CTPI method




Benefits:

• enhanced compression degree at the same (or less) reconstruction error;
• archivation mode option (distortion-free) or controlled-error mode option (at desired reconstruction accuracy of every image pixel);
• multi-resolution option, i.е. reconstruction of full-format image or demagnified copies (with varied rarefaction degree);
• high-rate data compression and decompression.
