===Description===
===Description===
Optional input (figure) sets the figure on which the current axes image(s) will be histogrammed with slider controls to allow adjustment of the color contrast. Histcontrast figure is modal and will only operate on one slab of an image at a time.
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.
