Detailed Description

Utility class to split an images roi into a set of shallow copies.

In some cases it is useful, to devide a task, that should be applied on an images ROI, into a set of disjoint subtasks. This can be achieved by generating a set of shallow copied images with disjoint ROIs. E.g. if we have a source image of size 320x240 (with full ROI). This can be split into e.g. 4 sub images with the following ROIs:

1. 0,0,320,60
2. 0,60,320,60
3. 0,120,320,60
4. 0,180,320,60

Of course, we can split the source images also vertically, but a horizontal cut is closer to the internal data representation, which is also aligned horizontally.

A common application for splitting images is multi-threading: Instead of applying a filter on an images ROI, the image can easily be split using the ImageSplitter, and the filter can be applied on each of the resulting images parts in a dedicated thread.

releases all images within the given vector

split() [1/2]

static std::vector<core::ImgBase*> icl::filter::ImageSplitter::split ( core::ImgBase *  src, int  nParts  )

static

splits a source image into given number of parts

split() [2/2]
