patternize: Quantification of Color Pattern Variation

Quantification of variation in organismal color patterns as obtained from image data. Patternize defines homology between pattern positions across images either through fixed landmarks or image registration. Pattern identification is performed by categorizing the distribution of colors using RGB thresholds or image segmentation.

Extracts color pattern from landmark transformed image using watershed segmentation. This function works interactively by allowing to pick a starting pixel within each pattern element from which the watershed will extract the pattern. This function works best for patterns with sharp boundaries.	patLanW
This function transforms the individual color pattern rasters as obtained by the main patternize functions to a dataframe of 0 and 1 values that can be used for Principal Component Analysis ('prcomp'). This function also allows to plot the analysis including a visualization of the shape changes along the axis. Pixel values are predicted by multiplying the rotation matrix (eigenvectors) with a vector that has the same length as the number of rows in the rotation matrix and in which all values are set to zero except for the PC value for which we want to predict the pixel values.	patPCA
This function transforms the individual color pattern rasters as obtained by the main patternize functions to a dataframe of 0 and 1 values that can be used for constrained Redundancy Analysis (RDA) ('rda'). This function also allows to plot the analysis including a visualization of the shape changes along the axis.	patRDA
