Comparative Analysis of K-RLE and LTC Methods for Measurement Data Compression with Losses Control
Konstantin K. Semenov, Adel B. Raimzhanova · 2025
The requirements imposed by metrology on measurement results restrict the feasibility of their archiving when large data volumes are involved - notably if one uses lossy compression methods. The introduction of uncontrolled distortions into the data contradicts the conditions of integrity, reliability, and validity of the measurement results. These challenges have led to a new class of algorithms - controlledloss compression methods. At the moment, the literature shows that this class contains the K-RLE and LTC methods. This paper presents a theoretical analysis of these approaches, investigating their properties and ultimate characteristics, including the achievability of the theoretical compression limit under controlled loss constraints.
