OpenCV puts all the above in single function, **cv.Canny()**. We will see how to use it. First
argument is our input image. Second and third arguments are our minVal and maxVal respectively.
Third argument is aperture_size. It is the size of Sobel kernel used for find image gradients. By
Fourth argument is aperture_size. It is the size of Sobel kernel used for find image gradients. By
default it is 3. Last argument is L2gradient which specifies the equation for finding gradient
magnitude. If it is True, it uses the equation mentioned above which is more accurate, otherwise it
uses this function: \f$Edge\_Gradient \; (G) = |G_x| + |G_y|\f$. By default, it is False.

Now you may ask -- if the matrix itself may belong to multiple *Mat* objects, who takes responsibility

This is handled by using a reference counting mechanism. Whenever somebody copies a header of a
*Mat* object, a counter is increased for the matrix. Whenever a header is cleaned, this counter
is decreased. When the counter reaches zero the matrix is freed. Sometimes you will want to copy

Now modifying *F* or *G* will not affect the matrix pointed to by the *A*'s header. What you need to
remember from all this is that:
- Output image allocation for OpenCV functions is automatic (unless specified otherwise).
- You do not need to think about memory management with OpenCV's C++ interface.
- The assignment operator and the copy constructor only copies the header.

For *colorful* ways we have a lot more methods to choose from. Each of them breaks it down to three
or four basic components and we can use the combination of these to create the others. The most
popular one is RGB, mainly because this is also how our eye builds up colors. Its base colors are
red, green and blue. To code the transparency of a color sometimes a fourth element: alpha (A) is
red, green and blue. To code the transparency of a color sometimes a fourth element, alpha (A), is
added.

There are, however, many other color systems, each with their own advantages:
- RGB is the most common as our eyes use something similar, however keep in mind that OpenCV standard display
system composes colors using the BGR color space (red and blue channels are swapped places).

Each of the building components has its own valid domains. This leads to the data type used. How
we store a component defines the control we have over its domain. The smallest data type possible is
*char*, which means one byte or 8 bits. This may be unsigned (so can store values from 0 to 255) or
signed (values from -127 to +127). Although in case of three components this already gives 16
million possible colors to represent (like in case of RGB) we may acquire an even finer control by
signed (values from -127 to +127). Although this width, in the case of three components (like RGB), already gives 16
million possible colors to represent, we may acquire an even finer control by
using the float (4 byte = 32 bit) or double (8 byte = 64 bit) data types for each component.
Nevertheless, remember that increasing the size of a component also increases the size of the whole
