Claim 10:
11. A system to be used in well inspection, the system comprising memory having instructions and at least one processor to execute the instructions that causes the system to:
determine one or more signals from a well inspection tool in a well structure;
generate variable density log (VDL) data from the one or more signals, wherein the VDL data comprises a plurality of waveforms in a time domain;
determine a number of independent components comprised in the VDL data based at least in part variances identified in the VDL data;
decompose the plurality of waveforms into multiple components using independent component analysis (ICA) and using a number of independent components determined in the VDL data, the multiple components associated with one or more local structure variances of the well structure; and
determine characteristics of the well structure based in part on patterns or features associated with the one or more independent components from the multiple components.
