I'm not quite sure how to play with the ApproxPolyDP settings, here is what is in my program currently: CvInvoke.ApproxPolyDP(contour, approxContour, CvInvoke.ArcLength(contour, true) * .05, true); What would I tweak and what does that change?

Okay, so how should I go about finding these half circles with lines?

I'm currently using Emgu CV, and I'm trying to locate a target such as the one below.image description

I attempted to use HoughCircle method to find the ellipses, but that isn't working for me; I suspect they are not "circular" enough. So how would I go about finding these ellipses?

I am currently running the edge detector before the circle detection, but they don't interfere with each other at all. They are separate processes. What does running HoughCircles on the image have to do with non-existent rotated rectangles showing up?

I'm doing rectangle detection using canny edges and contour detection using Emgu CV (example). I keep getting rotated rect's even though the objects are circles, see below: image description

What could be causing this? Also why is it missing the entire white rectangle?
