contrib/tbl/vepl2/vepl2_x_gradient.h File Reference


Detailed Description

Convolve image with horizontal [-1 1] filter.

Note that the user has to make sure that the output values fall into the output pixel range, by specifying appropriate scale and shift; wrap-around will occur if it does not.

Note also the implicit use of DataOut::DataOut(DataIn), which you probably will have to provide when DataIn and DataOut are not the same type.
