Minimum Entropy Models for Laser Line Extraction

Minimum entropy model can find the optimal gray space for laser line extraction. A global model named Minimum Entropy Deconvolution is established to search for the peaks which constitute the laser line. Not only does it reach a high accuracy, but also it retains the line smoothness, which the previous work often paid little attention to. Besides, this work could extract several laser lines. Experimental results show that the robust models and fast algorithms outperform the compared.
