Hello Mike,

In the vision_framework example given by you it is clear that the tcAlgorithmEdgeDetect::Process() class makes use of the IMG_sobel_3x3_16() library routine to perform a basic edge detection transform.

But in order to call IMG_sobel_3x3_16() IMGLIB function, we have to give the arguments like input_image size, output_image size, number of cols, number of rows, so how this has to be done?

Also do we need to use PRAGMA Directives like DATA_ALIGN to align the buffer on a byte boundary to be used by IMGLIB, DATA_SECTION if so with respect to your board how this has to be done?

Can you provide any example program of calling IMG_sobel_3x3_16() IMGLIB function, so that above questions will be answered.

Thanks in advance

with regards,
Naveen K.S
