In order to improve the measurement precision for visual measuring system, coordinate measuring mathematical models of two typical vision sensor systems of a line-structured light visual sensor and a symmetrical binocular visual sensor are investigated with the trigonometric method. The relationship characteristics between measuring errors and structure parameters of the line structured light vision...
Conditional random fields (CRFs) for sequence labeling offer advantages over both generative models like hidden Markov model (HMM) and classifiers applied at each sequence position. First, the CRFs don't force to adhere to the independence assumption and thus can depend on arbitrary, non-independent features, without accounting for the distribution of those dependencies. Since CRFs models are able...
