Abstract It will face a lot of problems when using existing image-processing and 3D
scanning methods to do the similarity analysis of the line traces, therefore, an
effective comparison algorithm is put forward for the purpose of making
effective trace analysis and infer the criminal tools. The proposed algorithm
applies wavelet decomposition to the line trace 1-D detection signals to partially
reduce background noises. After that, the sequence comparison strategy based
on wavelet domain DTW is employed to do trace feature similarity matching.
Finally, using linear regression machine learning algorithm based on gradient
descent method to More >
