Detailed Description

ImageViz SoImageStackProjectionProcessing3d engine

The SoImageStackProjectionProcessing3d engine creates a single image containing selected pixels from a stack of input images.

For example, when you make several acquisitions of the same object with different acquisition conditions, the images you get may not have the same focused areas. The SoImageStackProjectionProcessing3d engine examines all the images to get the best values of the sequence and build the resulting image.

When projectionMode is one of INTENSITY_MAXIMA, GRADIENT_MAXIMA or INTENSITY_MINIMA, the engine also generates an outLabelImage that shows the contribution source (i.e. the sequence number of the image from the input stack) on the result image outImage.

This engine can produce higher quality results than using the standard Maximum/Minimum Intensity Projection (MIP) rendering in VolumeViz.

For color images, it works in the HSL color space and uses only the lightness.

Member Enumeration Documentation

Enumerator:
GAUSSIAN_GRADIENT 

Compute a gaussian gradient (convolution with derivatives of gaussian function along the stack direction).

MORPHOLOGICAL_GRADIENT 

Compute a morphological gradient (see SoMorphologicalGradientProcessing for definition).

RECURSIVE_GRADIENT 

Compute a recursive gradient (Canny-Deriche on stack direction).

Enumerator:
INTENSITY_MAXIMA 

Select the pixel with the highest value of the sequence.

GRADIENT_MAXIMA 

Select the pixel with the highest gradient.

This mode enables the gradientOperator field.

PROJECTION 

Sum all values of the sequence.

INTENSITY_MINIMA 

Select the pixel with the lowest value of the sequence.

MEDIAN 

Select the pixel which is the median of the sequence.

MEAN 

Compute the average of the sequence.

VARIANCE 

Compute the variance of the sequence.

ENTROPY 

Compute the entropy of the sequence based on this formula:

\[Entropy= -\sum_{i \in seq} {P(x_i)*log(P(x_i))}\]

where $P(x_i)$ is the probability to have a pixel with value $x_i$ (it's the number of those pixels divided by the total number of pixels).

ENERGY 

Compute the energy of the sequence based on this formula:

\[Energy= \sum_{i \in seq} {P(x_i)^2}\]

.
