Hi, this is a toughy. I am quite prepared to up the points for this one at any time.
Right we have a webcam monitoring a security gate. I would like to reduce the amount of image data being sent. The solution I see as being optimal is as follows.
We would only like to transmit an image to the security workstation clients if there is a significant change in image detail, ie a truck parks at a gate or person(s) walk past.
This sort of coding is just way out of my depth, so I am asking for help.
The only technique I can think of is an edge-detection algorithimn that produces, say a monochrome map of all the sharp colour edges in the image and then only transmit it if the monochrome count is significantly different.
I don't know how to write an edge detection algorithim. Maybe if I convert it to 8-bit achromatic will help, but in general I feel a little overwhelmed.
Thanks in advance.
