Introduction The creaContours interface is divided in two principal parts: the visualization window and the button panel.
Visualization window   Brightness / Contrast: Drag middle click mouse Change Z: Drag right click mouse Zoom: Drag ctrl-right click mouse Move image: Drag shift-left click mouse Rotate image: Drag ctrl-middle click mouse Picker (position, gray level): Mouse move Contour Selection: Click-right over the contour (yellow contour selection) Contour PreSelection: Mouse over contour (gray conoutr preselection) Contour Move: Drag contour selected Contour Copie: Ctrl-C of a select contour Contour Paste: Ctrl-V Contour Edition: Double click-right over the contour selected (key points edition) Point selection: Mouse over the control point (yellow box selection) Point move: Drag point click-left (yellow box selection) Erase point: BackSpace over Point Selected Insert point: Click-right + DragMouse over the contour selected in the new point position Insert point: SpaceBar in the new point position
Button panel The buttons are divided into six categories: New Contour: These are the buttons that allow the user to place a contour over the image. The types of contour shapes from which the user can choose are represented by each different button. I/O: Basic save-and-open functionality. Edit: Undo, redo, paste and copy. Basic editing functions to make contour management easier for the user. Delete: Buttons that permit the user to erase one or many contours from an image or from a series. Contour Tools: Miscellaneous, unclassifiable tools that provide additional contour functionality. Segmentation: Various contour-based segmentation options. Image Tools: Miscellaneous, unclassifiable tools that provide additional contour functionality.

New Contour

 Permits the creation of a spline contour. The user selects the points that the contour is to contain, and creaContours creates the curve that goes through all of them.

  Permits the creation of a rectangular contour. The user chooses two points which are opposite and determine the rectangle's side length.

  Permits the creation of a circle contour. The point the user clicks on is a fixed on the circumference; the user can then choose the center and the radius of the circle.

  Permits the creation of a bull-eye shaped contour. The user simply chooses where to place it and how to size it.

  Permits the creation of a line contour. The user chooses two points, which define the beginning and the end of the line.

  Permits the creation of a points contour. As its name explains by itself, the user simply chooses where to place the points on the screen. He can have as many points as he'd like to.

  Permits the creation of a polygon contour. As is the case with the spline, the user chooses the points through which creaContours will draw the contour. The difference is that a polygon may have sharp "peaks" and is not, as thus, a soft "curve".

I/O

-  Used to open a previously saved contour (*.roi).

-  Used to SAVE AS a contour. Contours are saved as .roi files. Then you can use CTRL+S

 back up

Edit

-  Used to make a copy of the chosen contour.

-  Used to "paste" on the screen a previously made copy of a contour.

-  Used to undo the last performed action.

-  Used to redo an action that has been undone.

 back up

Delete

-  Deletes the last contour that's been chosen

-  Delete all the contours that have been placed on the current slide

-  Deletes all the contours that have been placed in all of the image's slices. This means that contours that are not currently visible might be deleted as well.

Contour Tools

-  The chosen contour will be replicated across all of the image's slices. As such, changing slices will not cause the chosen contour to disappear

-  Smoothing contour propagation

-  Mirrors a contour. The user chooses the mirroring axis and the contour that's to be mirrored. The chosen contour will be mirrored around the axis once the user clicks on " mirror="" contour"

-  Used to write a tag name to a previously chosen contour

-  Flip contour

back up

Segmentation

-  Does an automatic segmentation of the current slice of all slices. The process requires the input of several parameters. Click on the button thumbnail to find out more about this functionality

- Automatic segmentation ITK

-  Not yet functional. This button should let the user put a snake active-contour on top of the image. This contour could then be dynamically deformed according to the snake mathematical model
