Detailed Description

Utility functions for basic image conversion and manipulation.

Groups helpers for converting between 1D/2D coordinates and for generating colour visualisations from integer labels.

createRandomColor()

static ImageUInt8Ptr mmcfilters::ImageUtils::createRandomColor ( int *  img, int  numRowsOfImage, int  numColsOfImage  )

inlinestatic

Creates a random-colour visualisation from an integer-labelled image.

The output is a row-major uint8_t image with three adjacent columns per input pixel, storing RGB triples as (R, G, B). Labels are used as array indices and therefore must be non-negative.

Parameters

img	Pointer to numRowsOfImage * numColsOfImage integer labels.
numRowsOfImage	Number of input rows.
numColsOfImage	Number of input columns.

Returns

RGB visualisation encoded as an image with numColsOfImage * 3 columns.

Definition at line 302 of file Image.hpp.

to1D()

static int mmcfilters::ImageUtils::to1D ( int  row, int  col, int  numCols  )

inlinestaticnoexcept

Converts (row, col) to a row-major linear index.

Parameters

row	Zero-based row coordinate.
col	Zero-based column coordinate.
numCols	Number of columns in the image domain.

Returns

Linear index row * numCols + col.

Definition at line 272 of file Image.hpp.

to2D()

static std::pair< int, int > mmcfilters::ImageUtils::to2D ( int  index, int  numCols  )

inlinestaticnoexcept

Converts a row-major linear index to (row, col).

Parameters

index	Row-major linear index.
numCols	Number of columns in the image domain.

Returns

Pair (row, col).
