Project explorer

Workspace setup

The workspace consists of a hierarchy of 3, with workspace as the top, followed by object and course. It is a way of grouping the projects into intuitive categories. Each workspace can contain multiple objects, and each object can contain several courses. Each course can have one or more pictures attached, together with a date, and the measurements made here are the basis for the graphs and report generation. This will be elaborated later, now we will focus on the workspace setup.

As an example, workspace could be the department, object the patient and course the individual disease.

After a workspace, object or course has been created, they are available through a drop-down menu.

Three buttons are available: Add, Edit and Delete.

Images

The images in the selected course will be shown in the image explorer. When an image is marked, it will show up on the drawing board, ready to be measured or show existing measurements. The image contains information regarding date and a description, which both are altered in the image explorer shown to the right. By clicking the date, a calendar will appear, and a date can be selected. The description is altered by clicking the empty field and text is entered by typing.

Results

When an image has been selected, the results for that image will be visible in the result overview. To give a better overview, each  measurement can be given a name. When newly created, the measurements will be called figure 1, figure 2, figure 3, etc. By clicking the name, it can be changed to a customized name. In this example, the names Area, Height and Width are chosen. When an area measurement is made, length refers to circumference and area to surface area.

Acquire Image

The menu shown below has to do with importing/saving images.

Add image from folder

Save image

Delete image

Add image from scanner / camera / microscope

Add image from folder

Open an image directly from a location on the computer. Upon clicking (Add image from folder), a dialogue box will appear. This dialogue box allows you to browse your local hard drive for the image you want to open. Mark the image and press “Open”.

Another option is to drag and drop the image into the software. Open Windows Explorer, and locate the folder where the image you want to acquire is located. Drag the image into the software. This will automatically import the image.

Import from WIA/TWAIN source (Camera, webcam, scanner, microscope etc.)

To import directly from a WIA or TWAIN source, press (Scan). This will open a dialogue box where the video is captured, together with an option for adjusting the settings. Press Format or Preferences to change video-settings, or press Snapshot to capture the current image displayed.

This will automatically import the image.

When acquiring image from a scanner, camera or microscope, the device has to be WIA or TWAIN compatible. All sources using the WIA or TWAIN platform can be used to acquire images directly into the software.


Image adjustment

To adjust the image, In order to optimize the measuring process, the toolbar shown below is used.

Zoom in

Zoom out

Zoom select

Adjust / fit to window

Adjust to actual size

Rotate left

Rotate right

Image effects

Crop

Skew correction

The top 5 tools, which all have to do with zoom, can be used at any time in the measuring process.

The bottom 4 tools, where the picture is adjusted, are available before calibration.


Calibration

When the image has been imported, the first step is to calibrate the measurements. This action basically sets the scale that all future measurements on the image in question are based on.

Practically, this is done by measuring a known length, normally a ruler. The ruler is often used, because it is a direct and simple way of showing the scale of the image, both when calibrating our software and for visual reference for the user.

Other objects can be used, however. Any object where a dimension is known is usable.

Note: When acquiring the image, make sure that the ruler are in the same depths or level as the wound, and that the ruler does not cover parts of the wound. As an example, if the ruler is placed on the table and the wound is on the arm, the difference in depths relative between the two, will make the measurements less accurate. The closer the ruler is placed to the wound, the more accurate the result will be.

Manual calibration

After an image has been acquired, the (Calibrate) tool is automatically selected.

Before calibrating, choose the desired unit and how many units you are calibrating with. Basically, calibrating is adjusting the scale of the image. This is done by measuring a known length on an object, to use as a reference for all future measurements in the individual image. This is often a ruler. Choose the desired amount and unit, thereafter measure the object. Left-click once where you want to start the calibration, double-left-click where you want to end the calibration. When this is done, the measuring tools are available.

Fixed calibration

Fixed calibration is done the same way as described under manual calibration. The difference is that the calibration is fixed and automatically used for all future measurements within the workspace, object, course or the entire application. When choosing fixed calibration in the Settings menu, choose whether you want it to be for the course, object, workspace or whole application. This means that the current calibration on the selected image is used for future images.

Automatic calibration

This feature automatically recognizes a distinct square shape, and uses the diagonal as the calibrated length. This is used if the same ruler (or any other square with a known length) is used every time. Type in the default calibration value, and choose Automatic Calibration. When an image is acquired, the image will be calibrated and ready to be measured. This requires Automatic calibration to be applied, and a square shape to be present in the image.

The option for automatic calibration, allows for the software to automatically detect rectangle and add a user-defined length of the diagonal. On the left is shown an example of how the automatically detected ruler could look like.

Most important is an easily detected color, and that the rectangle has a known diagonal length. The diagonal length is shown with the dashed line marked with a d above.

When the option for automatic calibration is chosen, all future images will be calibrated detecting the ruler and applying the given diagonal.


Measuring

Toolbar

When measuring, two different toolbars are used. They are shown below.

Copy

Paste

Delete selected measurement

Delete all measurements (clear)

Edit polyline

 

Select

Measure area

Measure length

Measure angle

Magic wand

These tools are available after image has been calibrated.

Measure surface-area/circumference

To measure surface-area and circumference with the (Area Measurement) tool, left-click once to initiate the drawing. Left-click around the edges of the objects to trace the contours. Use as many or as few points as you wish. The figure is closed automatically, and double-left-click on the last point to end the drawing.

Use the (Edit polyline) tool to adjust the figure after drawing. Upon selecting this tool, red dots will be added where the tracing points has been placed. These can now be dragged into a new position by dragging existing points, new points can be added by clicking where there is no points or removed by pressing ctrl + left mouse click on existing point.

Magic wand

The magic wand is used to automatically detect a figure on the image. To measure surface-area and circumference with the (Magic Wand) tool, adjust the tolerance and max points in the Settings menu. The tolerance is how big a color difference the wand should accept. Too high a value will measure outside the object, too low a value will not measure the whole object. Left-click once on the object and the contours will automatically be traced.

After the measurement has been made, the line can be edited by using the (Edit polyline) tool. The individual points will show up in red, and they can be dragged to tune the figure.

By clicking at the line where no red dot present, a new point will me bade. By holding down “Ctrl” on the keyboard and clicking an existing point, it will be removed.

Note: The magic wand will sometimes be inaccurate, due to lack of contrast and little in the pictures. This tool is mainly used for measuring on drawn images

 

Tip: Always start measuring by left-clicking once and end the measuring by double-left-clicking.

Manuel surface area / circumference

Click the (Area Measurement) tool and initiate the measurement by left-clicking once where you want to start the figure. Now click along the circumference, to draw the outline. The drawing is ended by double left-clicking with the last point
you make.

The tool can also be used by holding down the left mouse button, and drawing the outline. Besides that, the tool is used in the same way as described above.

After the measurement has been made, the line can be edited by using the (Edit polyline) tool. The individual points will show up in red, and they can be dragged to tune the figure.

By clicking or dragging the line where no red dot is present, a new point will be made. By holding down “ctrl” on the keyboard and clicking an existing point, it will be removed.

Manuel length

To measure a length, use the (Line Measurement) tool. Left-click once where the line starts, left-click along the path of the intended line and double-left-click on the last point to end the line.

After the measurement has been made, the line can be edited by using the (Edit polyline) tool. The individual points will show up in red, and they can be dragged to tune the figure.

By clicking at the line where no red dot present, a new point will me bade. By holding down “ctrl” on the keyboard and clicking an existing point, it will be removed.


Export

.CSV

If several images in a series has been analyzed, and the data needs to merged with other data and analyzed in another software e.g. Excel, statistical software or any other 3rd party software, .CSV file can be useful. It is a flexible file type readable by many applications. All data, except the images itself, are exported into the .CSV file.

The export function are located under Data > Export > CSV Export.

Burned image

The currently selected image can also be exported as an image with the result annotations stamped into the image. It gives a quick and easy option for creating simple documentation. This is done by selecting Data > Export > Burned Image.

The image can either be saved as .TIF or .JPEG. On the right is an example of how the burned image looks.

Embedded image

If the Save as function is used, an image with embedded measurements is saved. All the measurements are embedded into the file. This means that if the image is opened in a normal image viewer or image editor software, the measurements are not visible. If the image is opened later in a KLONK Image Measurement application, all the data will be retrieved. This can be useful for sharing images and results with coworkers, partners etc.


Documentation

Graph

When multiple images placed under one course has been analyzed and measured, a graph can be presented to show the progress over time. The graph will show all the available data sets in the image as separate lines, easily comparable.

To switch between the view of the drawing board and the view of the chart, click on the tabs below the main window.

Report

Predefined reports can be generated, either to be used as documentation, reports, and appendixes for reports or statistical analyses. The reports are generated by choosing Data > Report and then the part of the data which are supposed to be used for the report.
