Figure 15From: Automated detection of elephants in wildlife video Closing gaps in tracking and interpolated segments. Closing gaps in tracking for two frames where tracking was not successful (a). Since tracking establishes temporal relationships over several frames, the gaps can be closed (b). The segments (red contour) are interpolated using optical flow. The original link (dashed, gray) is replaced by new temporal links (solid, red). Green lines represent temporal relationships obtained by region tracking.Back to article page
