Image3DProjection

Image3DProjection[image]

takes a 3D image and returns a 2D image of maximum projection onto the - plane.

Image3DProjection[image,dir]

performs a projection in the direction specified by dir.

Image3DProjection[image,dir,mode]

specifies the projection mode.

Details

  • Image3DProjection is a way of seeing the structure inside a volume.
  • Image3DProjection[image] is equivalent to Image3DProjection[image,Bottom,"Max"].
  • Possible settings for dir include:
  • Left,Right,Front,Back,Top,Bottomplanes to project to
    wa 3D vector specifying the direction of projection
    {w,vert}aligns the vertical of the projection to vert
  • The default projection plane is Bottom, corresponding to projection direction {0,0,1}.
  • The default vertical is the direction unless the projection plane is Top or Bottom, in which case the default vertical is the direction.
  • For an arbitrary direction of projection, the resulting image represents the smallest rectangle that encloses the entire rotated volume. This cropping corresponds to Automatic size in ImageRotate.
  • Possible settings for the projection mode include:
  • "Max"color of the pixel with the maximum intensity value
    "MaxIntensity"maximum projection of the grayscale volume
    "Mean"mean projection for every color channel
    "MeanIntensity"mean projection of the grayscale volume

Basic Examples  (2)

Maximum intensity projections:

Project color of the pixel with maximum intensity:

Scope  (3)

By default, the projection is performed onto the - plane:

This is the same as specifying "XY":

Project onto the "XZ" plane:

Project onto the "YZ" plane:

Specify an arbitrary direction:

By default, maximum projection is performed:

Perform mean projection:

Maximum projection of a color volume:

Maximum intensity projection of a color volume:

Mean projection of a color volume:

Mean intensity projection of a color volume:
