Detailed Description
Reduce the size of an image by an integer factor in each dimension while performing averaging of an input neighborhood.
The output image size in each dimension is given by:
outputSize[j] = max( std::floor(inputSize[j]/shrinkFactor[j]), 1 );
The algorithm implemented can be describe with the following equation for 2D:
![\[ \mathsf{I}_{out}(x_o,x_1) = \frac{\sum_{i=0}^{f_0}\sum_{j=0}^{f_1}\mathsf{I}_{in}(f_0 x_o+i,f_1 x_1+j)}{f_0 f_1} \]](form_32.png)
This filter is implemented so that the starting extent of the first pixel of the output matches that of the input.
The change in image geometry from a 5x5 image binned by a factor of 2x2. This code was contributed in the Insight Journal paper: "BinShrink: A multi-resolution filter with cache efficient averaging" by Lowekamp B., Chen D. https://hdl.handle.net/10380/3450
