Clear path detection using edge detection

Hi,
I want to create an application where a user can detect an unobstructed path using an Android mobile phone. I used a Gaussian filter for smoothing and then used canny edge detection to detect edges.
I thought if I could find the concentration of edges in the video I can direct the user towards an area with a low concentration of edges, hence a clear path.
Is there a way to find the concentration of the edges? I'm new to image processing so any help would be appreciated.
Thank you

There is not standard functionality in OpenCV that provides exactly what you want. However, edges are basically binary maps (or can be represented as such) making it possible for you to detect the amount of white pixels versus the amount of black pixels in a region. This could define a measurement of edge concentration, like you describe it.

In general, if any kind of edge detection is desired it would avoid blurring as it actually makes the edge detection only harder. If filtering is needed then use a median or a bilateral filter as these are edge-preserving.
