Fig. 6From: Dynamic turbulence mitigation for long-range imaging in the presence of large moving objectsComparison of three optical flow methods: Lucas-Kanade (a–c), Horn-Schunck (d–f), and TV-L1 (g–i). The left column shows the turbulence mitigation results for the same frame as Fig. 5, whereas the middle and right column show the estimated motion per pixel for that frame expressed in units of pixels per frameBack to article page
