no matching function for call to 'erode"

[lochoang75]

I try to build example same as tutorial and document but i got some problem with argument in xf: :erode, xf::dilate with wrong matching function call.
error log:

The code in this tutorial in not correct. Please have a look at the source code of function erode, it is defined as:
void erode (xf::Mat<TYPE, ROWS, COLS, NPC> & _src, xf::Mat<TYPE, ROWS, COLS, NPC> & _dst,unsigned char _kernel[K_ROWS*K_COLS])
There are 3 parameters in the function, however the code in the tutorial only calls the erode with 2 parameters. You should edit the code to as following:

xf::erode<XF_BORDER_CONSTANT, XF_8UC1, HEIGHT, WIDTH, XF_SHAPE_RECT, 3,3,1,XF_NPPC1>(_range, _erode,kernal);

Add the 3rd parameter in the function call, the varialbe kernal is a 3*3 matrix, and I set all the element value to 1

Are you using the tutorial with the 2018.3 release of the reVISION platform and xfOpenCV library? If so, then you'd be needing to stay with the 2018.2 release of the platform and library. The tutorial is getting a major rework right now for 2018.3. The xfOpenCV library had gotten some major work done in 2018.3 with the function definitions and as you pointed out the kernel parameter.

Thanks for your help. I have already seen that difference.
