The following Matlab project contains the source code and Matlab examples used for identification of piecewise linear and homogeneous zone detection.
Project:1D signal:Identification of PieceWise Linear by multiple regression
Detection of homogeneous zone using entropie
Projection in the Hough space (1D) I/O
Inputs: 1D signal (xe,ye)
Simulated data (Figure 12);
Outputs: Entropie signal (xee,yee)
Line positions, position
Line lengths, longueur
Line slopes, pente
Error of regression, e
Identification of PieceWise Linear (Figure 1)
Projection in the Hough space (Figure 2,3)
Identify homogeneous zone of a signal (detect also singularity or abrupt changes)(Figure 1)
Projection in the 1D Hough space (Length of the line,position of the line) (Figure 2,3).
