Detailed Description

Spectral Cube exports.

Version: 0.2.0.0

An Image Cube (or Cube) is a representation of a hyper spectral image. To put it in perspective with conventional images: A gray scale image has one value for each pixel. A RGB image has three values for each pixel. An Image Cube however contain of n values for each pixel. These values are located in the spectral domain which is also referred to as band. The number of bands is equal to the number of wavelengths defined in the Image Cube.
In CVB an Image Cube object consists of a Meta Data and a buffer view.

The Meta Data contains information on the Image Cube and is holds a list of fields. Most notable field here is the Interleave. This value defines the orientation of the Image Cube.
The buffer view is an Image object which handles the pixel access. Accessing a pixel is done in the conventional CVB way using the VPAT (or Linear Access).

The dimensions of the Image Cube are referred to as sample in the range [0, Samples[, line in the range [0, Lines[ and band in the range [0, Bands[ . The dimensions of an Image in CVB are referred to as x in the range [0, width[ , y in the range [0, height[ and z in the range [0, dimensions[ The Interleaved value in the Meta Data defines the mapping between these two spaces.

There are four distinct types of Image Cubes: Continuous Image Cubes, Mapped Image Cubes, Stacked Image Cubes and Linear Non-Owning Cubes

A Continuous Image Cube owns a linear buffer. In this buffer each pixel is order in a sequential order without any mapping. This allows fast linear pixel access.
In Contrast a Mapped Image Cube references a Continuous Image Cube and accesses its buffer. Here the view on the buffer is mapped. In this case this means that XInc, YInc and ZInc have been swapped. This enables fast transpose operations without copying the buffer. As a drawback the linear pixel access may be slower then with Continuous Image Cubes.
Stacked Image Cubes are used to initialize Image Cubes through an array of Images. This Image Cube makes no copy of the Image Buffer but instead references each buffer. Therefore make sure that all Image buffers are not deleted during the lifetime this cube. To transpose a Stacked Image Cube call CVSCreateContinuousCube first.
Linear Non-Owning Cube can be created from any linear buffer. This makes this kind of cube highly flexible and allows a broader range of applications. The drawback is that during lifetime the buffer is potentially invalidated.

For details see function documentation.

Enumeration Type Documentation

◆ CVSCubeEncoding

enum CVSCubeEncoding

Cube Encoding.

Defines how the mapping between a typical x-y image and samples-lines-bands is done. When acquiring images the interleaved type depends on the technology the imaging sensor uses to acquire spectral data. A sequence of images is returned by the camera in the following manner: [xSensor ySensor time] Now depending on the spectral imaging sensor the these dimensions are mapped to samples, lines and bands

Sensors using the pushbroom approach (spatial scanning) deliver images in the CVSVP_BandInterleavedByLine manner: [samples bands lines]
Sensors using tunable spectral filters (spectral scanning) deliver images in the CVSVP_BandSequential manner: [samples lines bands]
Sensors using snapshot approach may deliver images in the CVSVP_BandInterleavedByPixel manner: [bands samples lines]

When viewing a spectral cube the spatial dimensions are mapped in the following manner:

samples: xDisplay
lines: yDisplay

Enumerator
CVSVP_BandInterleavedByLine	Sensors using the pushbroom approach (spatial scanning) deliver images in the CVSVP_BandInterleavedByLine manner: [samples bands lines].
CVSVP_BandSequential	Sensors using tunable spectral filters (spectral scanning) deliver images in the CVSVP_BandSequential manner: [samples lines bands].
CVSVP_BandInterleavedByPixel	Sensors using snapshot approach may deliver images in the CVSVP_BandInterleavedByPixel manner: [bands samples lines].

◆ CVSCubeType

enum CVSCubeType

Cube Type.

Defines a the type of the cube

Enumerator
CVSCT_ContinuousCube	Linear Cube with owning buffer.
CVSCT_LinearNonOwningCube	Linear Cube without owning buffer.
CVSCT_MappedCube	Mapped Cube holds a reference of a Continuous Cube.
CVSCT_StackedCube	Stacked Cube with potentially non-linear buffer.

◆ CVSNormalizationMethod

enum CVSNormalizationMethod

Normalization Method.

Defines the method used for normalizing the spectral cube with a white and a black reference.

Default case: CVSNM_AverageReferences1 This means that first the average line of the White Reference and the Black Reference is calculated [Samples x Lines x Bands] --> [Samples x 1 x Bands]). The forumla used for calculating the normalization is then: (ImgCube - BRef) / (WRef - BRef)

Enumerator
CVSNM_AverageReferences1	White and Black Reference are averaged ([Samples x Lines x Bands] --> [Samples x 1 x Bands]) The normalization formula used is: (ImgCube - BRef) / (WRef - BRef)

	)

Retrieves a cropped image cube.

There are two options on cropping an image cube: Mapped and by Buffer When cropping an image cube with TargetMapped = true, the buffer is not copied. Instead the target image cube contains a mapped bufferView which references the source bufferView. There reference count of the source image cube is incremented internally. When cropping in image cube with TargetMapped = false, the cropped subset of the buffer is duplicated to the new image cube.

Parameters

[in]	ImageCube	Handle to the input image cube
[in]	ClipBox	The borders of the Clipbox (Min and Max) are included in the target
[in]	TargetMapped	Flag to define if the output image cube shall be cropped by mapping or by creating a new buffer
[out]	ImageCubeOut	Handle to the output image cube

◆ CVSCreateTransposedCube()

cvbres_t CVSCreateTransposedCube	(	CVCOMPOSITE	ImageCubeIn,
		CVSCubeEncoding	TargetCubeEncoding,
		cvbbool_t	TargetMapped,
		CVCOMPOSITE &	ImageCubeOut
	)

Transposes an ImageCube.

Creates a transposed ImageCube. The number of Samples, Lines and Bands are equal but the order in the buffer is different The TargetMapped flag determines the way the ImageCube is transposed:

true: The BufferView is mapped. In this mode only Continuous and previously transposed ImageCubes are accepted. To call this function with Stacked ImageCubes - which were previously created with an array of images - need to call the function CVSCreateDuplicatedContinuousCube first. The buffer is not copied in this operation. This operation is way faster than transposing the buffer itself.
false: In this mode the whole buffer is transposed. In this case all kinds of ImageCubes are accepted as input. The returned ImageCube contains a continuous buffer which is ideal for fast plane wise access (CVSCubeGetSlice). This operation itself is slow.

Parameters

[in]	ImageCubeIn	Input image cube handle
[in]	TargetCubeEncoding	Target Cube encoding
[in]	TargetMapped	Set this flag to false to transpose the buffer (slow). Otherwise to true in order to transpose the view (fast)
[out]	ImageCubeOut	Transposed image cube handle

Returns
