convlution

Hi,
I need to perform a convolution of an image with one dimensional mask
to find edge contributions in horizontal and vertical directions.What is
the best method to do this?
Thanks

The glib answer is, "Apply the mask and perform the convolution." What's 
the real question?

The real question would be What is an edge? And from that follows the
one he asked: What is the best method for detecting it?
	He should google for "Canny" "Prewitt" "Roberts" "Sobel" and he will
find dozens of web pages that compare edge detection methods and attempt
to answer his question.

Thanks Jim for the answer. I found some good documentation for those
