Figure 3: Enlarged images of midges as captured by our cameras.
From: Three-dimensional time-resolved trajectories from laboratory insect swarms
(a) A representative single midge as detected by the image processing algorithm. (b) A typical occurrence of a non-circular detected area that corresponds two two individual midges. These areas are split into two separate groups of pixels, each corresponding to a single midge, to improve the stereomatching rate. (c) An example of a large detected area that corresponds to a single midge that may potentially be obstructing another midge. These areas are duplicated in place to allow the line of sight through this midge from one camera to intersect with multiple lines of sight from the other cameras.
