Examples

Input	Long Flags	Short Flags	Output
	--colored --threshold 9 22	-c -t 9 22
	--colored --threshold 9 22 --stroke 1	-c -t 9 22 -s 1
	--threshold 9 22	-t 9 22

Kernel convolutions' implementation

Instead of padding the image with black pixels i'm cropping the kernel to fit available pixels.

For example:

Given a kernel of 5x5 dimensions, on the first pixel (0, 0) theres no pixels before it to accommodate the kernel thus it is cropped for only available pixels and applied for the (0,0) pixel.

python3 main.py [filename] [flags]

Flags

Long Flags	Short Flags	Description
--threshold	-t	One or two numbers representing lower and upper thresholds.
--colored	-c	Set this in order to apply color to the edges according to their direction.
--stroke	-s	A number representing the width of the output edge.
