Abstract

Laminated sediments from lakes are of great interest paleoclimatologists interested in high resolution records of past climate change. In this paper, laminated sediments from Lake Malawi in East Africa are investigated by X-ray analysis. Due to the physical nature of sediments, X-ray images having penetrated through sediments are corrupted by signal dependent nonstationary noise, which affects the accuracy and precision of time-series and spectral analysis of patterns. Therefore, a nonlinear pre-filtering algorithm is proposed to suppress the noise, so that more stable and reliable analysis can be obtained. The algorithm is based on the generalized weighted regularization.
