Research investigating the use of Legendre moments for pattern recognition has been performed in recent years. This field of research remains quite open. This paper proposes a new technique based on block-based reconstruction method (BBRM) using Legendre moments compared with the global reconstruction method (GRM). https://www.spidertattooz.com/iOptron-HAE43EC-Strain-Wave-AZ-EQ-Mount-w-iPolar-High-Precision-Encoder/
