PCA models of image data can be explored using IMAGEGUI. The function creates a set of linked score density plots along with a pseudocolor image based on the scores on the first 3 PCs. Users can select areas on any of the plots, and the pixels selected will be highlighted in the other plots. IMAGEGUI can also be used to select data from the model as the original pixel indices of the data associated with selected areas can be saved to the workspace. Indices are saved as a cell array with each successive selection being the next cell in the array. | |||

Purpose
Interface for Exploring Image PCA Scores.
Synopsis
- varargout = imagegui(action, fighand)
Description
PCA models of image data can be explored using IMAGEGUI. The function creates a set of linked score density plots along with a pseudocolor image based on the scores on the first 3 PCs. Users can select areas on any of the plots, and the pixels selected will be highlighted in the other plots. IMAGEGUI can also be used to select data from the model as the original pixel indices of the data associated with selected areas can be saved to the workspace. Indices are saved as a cell array with each successive selection being the next cell in the array.
