Method Detail

position

public opencv_dnn.BlobShape position(long position)

Overrides:

position in class Pointer

all

@ByVal
public static opencv_dnn.BlobShape all(int ndims,
                                              int fill)

Creates n-dim shape and fill its by \p fill

all

@ByVal
public static opencv_dnn.BlobShape all(int ndims)

dims

public int dims()

\brief Returns number of dimensions.

size

@ByRef
public IntPointer size(int axis)

\brief Returns reference to the size of the specified \p axis. Negative \p axis is supported, in this case a counting starts from the last axis, i. e. -1 corresponds to last axis. If non-existing axis was passed then an error will be generated.

get

@ByRef
 @Name(value="operator []")
public IntPointer get(int axis)

Does the same thing as size(int) const.

xsize

public int xsize(int axis)

\brief Returns the size of the specified \p axis. Does the same thing as size(int) const, but if non-existing axis will be passed then 1 will be returned, therefore this function always finishes successfully.

canonicalAxis

public int canonicalAxis(int axis)

\brief Converts \p axis index to canonical format (where 0 <= \p axis < dims()).

total

@Cast(value="ptrdiff_t")
public long total()

\brief Returns the product of all sizes of axes.

total

@Cast(value="ptrdiff_t")
public long total(int startAxis,
                                           int endAxis)

\brief Computes the product of sizes of axes among the specified axes range [\p startAxis; \p endAxis). \details Negative axis indexing can be used. \sa Blob::total(int,int)

total

@Cast(value="ptrdiff_t")
public long total(int startAxis)

slice

public opencv_dnn.BlobShape slice(int startAxis,
                                         int endAxis)

\brief Constructs new shape from axes in range [\p startAxis; \p endAxis). \details Negative axis indexing can be used. \sa Blob::total(int,int)
