Image Compare

Valid from DeltaPix InSight v6.2.9

 

Images can be compared in a number of ways.

The compare functions in many ways replicated the functionality of a traditionally ‘analogue’ comparison microscope – but much simpler and more flexible to use. Only one light setup is required – no need to do tedious work to set up identical right and left sides.

A reference image can be directly captured from the live camera image, or a stored still image can be set as reference.

The ‘Compare Image’ is located in the ‘Image Compare’ tab.

Sequence to prepare a compare session:

1.Select the "Sample A". This can be a still or the camera live image. Optionally a live comparison can be done, then select from the drop down.

2.Select the "Sample B". This can be a still or the camera live image.

3.Click the "Start Compare". This will spawn a new comparison image.

4.Different kinds of comparisons can be done, select from the drop down combo box.-

None - no comparison is done

Difference - the images are subtracted.

Alpha blend - the images are added, 50% from each.

Horizontal - the images are split and shown side-by-side.

Vertical - the images are split and shown side-by-side.

Aligning the Sample B.

 

The sample B can be aligned using the Angle, DX and DY sliders.

 

Note: The DX and DY range can be extended by  Alt and Ctrl modifier keys:

the Alt Key extends by a factor of 2

the Alt Control extends by a factor of 2

the Alt+Ctrl Key extends by a factor of 4

 

 

Alternatively the sample B can be aligned using the mouse.

Use the mouse wheel to rotate.

Push the mouse button and drag the image.

The Sample A and B can be swapped

 

The "Setup" button defines a remapping function  – it applies to both the live and the reference image.

This can enhance e.g. the evaluation of difference comparisons.
