Analysis of Effect of Radiometric Resolution on Radiometric and Phenological Normalization

摘要

Recently, the remote sensing sensors have been improved, which has led to improvements in spatial, spectral, radiometric, and temporal resolution of remote sensing imagery data. However, as resolution increases, the complexity of data also increases and results in high data volumes and storage issues. In particular, radiometric resolution refers to the number of bit depth divisions, associated with the sensitivity and processing time in radiometric normalization. Therefore, this study analyzes the effect of radiometric resolution on the radiometric and phenological normalization, which is preprocessing for multi-temporal satellite images. The experiments are carried out using fine and low scale resolution images, and the accuracy and computational time are evaluated. The experimental results show that low radiometric resolution is advantageous in terms of information and computational complexity.
