Chromatogram data compression based on linear fitting of time series

ZHANG Jie1,2,DU Yi1,2,LU De-tang1,2,LI Dao-lun1,2(1.Institute of Engineering and Science Software,University of Science and Technology of China,Hefei Anhui 230027,China;2.Key Laboratory of Computation and Communication Software of Anhui,Hefei Anhui 230001,China)  
A new segmenting algorithm of time series was proposed to satisfy the requirement of processing chromatogram data of well-logging.The key points that denote the varying trend of the sequence were selected according to some thresholds through one scan of the data.These selected points were used to fit time series linearly.The experimental results show that this algorithm can eliminate the noises without loss of the rough shape,and find the inflexion and the peak subsequences accurately.
