) [static]

It's the core of all the algorithm. It's quite "simple" in its writing but also very useful coz let you understand how all this stuff works. It's a static func. Will be called by the motion detector class OmniMotionDetecting.

Parameters:
omni_frame Omnidirectional frame on which you wanna perform the descripted tasks
theta_start The start angle of a range in which some motion has occurred.
theta_end The end angle of a range in which some motion has occurred.
win_length Lenght of the angle, it's size or it's range. Call it as you want...
callback_data Usually the "this" pointer, so that private members can be accessed too.

)

Unfortunately this is not really performant and bug free on a multiplatform fashion. This is because we can set the display callbacks to act like we want with other libraries. With this function you will call the "register_image_callbacks" of the classes that support this and are included in this class.

Parameters:
create_image_context Create window [with a title] where to display the images.
image_show Perform the call to the show function.
destroy_image_context Destroy the display window and it's context.
callback_data Callback data to image_show function.
