Detailed Description

Class to setup an images border pixels.

Border pixels are all pixels, that are not within the images ROI. The ImgBorder class provides three different strategies to setup these pixels with defined values:

fixed

This strategy sets all pixels to a fixed value, that is given by a 2nd argument to the "fixed"-method. To optimize performace, this function does only allow to set up Img<T>-borders with T-values. Hence it is realized as a template function.

copy

The copy strategy is an analogue to the IPPs "ippCopyReplicateBorder_.." function. It will extrude the images ROI edges towards the images borders.

fromOther

The last strategy is to copy the border pixels from another given Img.

Member Function Documentation

copy()

static void icl::core::ImgBorder::copy ( ImgBase *  poImage )

static

sets up an images border by extruding the images ROI pixels towards the image border

Parameters

poImage

destination image

fixed()

template<class T >

static ICLCore_API void icl::core::ImgBorder::fixed ( Img< T > *  poImage, T *  ptVal  )

static

sets up an images border with a fixed value

Parameters

poImage	destination image (with channel count C)
ptVal	destination value (for each of the C channels)

fromOther()

static void icl::core::ImgBorder::fromOther ( ImgBase *  poImage, ImgBase *  poOther  )

static

copies an images border from another image

Parameters

poImage	destination image
poOther	source image for the border data. This image must have the same size and channel count as poImage. The function will print a warning and return immediately without any changings otherwise.
