labelCells: Interactive Session for cell labeling

Description

The functions creates an interactive session in order to label cells with their classes. The labeled cells can be used as training set for the classifier. Note!! This is until now only tested for MacOsX.

Usage

labelCells(img, segmentedImage, classes, classColours, nblocks = 3, labeledPoints = NULL, filename = NULL, filenameImage = NULL,transformCoordinates=FALSE)

Arguments

img

The image.

segmentedImage

The segmented image.

classes

The possible class labels.

classColours

The colors for the class labels.

nblocks

The image can be separated in several blocks, as zooming is not possible.

labeledPoints

Labeled cells from a previous training session.

filename

The table of labeled cells is saved at this location.

filenameImage

The image with the labeled cells is saved at this location.

transformCoordinates

deprecated

Value

A table with columns: index: the index of the cell in the segmented image. x: x-coordinate of the cell y: y-coordinate of the cell classCell: Label of the cell xLocal: Local x coordinate in the subimage(block) yLocal: Local y coordinate in the subimage(block) block: Block number in which the cell arises.

Details

Use the keys: a: In order to add a label to a cell. d: In order to delete a label from a cell. c: To switch between classes. q: To quit the interactive session. r: To refresh the session (labeled cells will be shown after refreshing)
