Fig. 8

a - c shows some key point prediction results of our method. d -f shows arc lengths found using our method. The colours red, blue, orange, green and magenta represents the arc segments fg, gh, jl, kl, lm respectively. g - i shows key point and arc length predicted for the same images using the WINGMACHINE software. Red arrows are used to indicate the errors for clarity. The errors in g and i are due to incorrect prediction of joint locations while the error in h is due to a bad fitting results of an a priori template wing. Lastly, j - l shows three examples of bad arc length estimation results found using Active Contour due to artefacts in the background such as air bubbles and dust particles. The red arrows show the artefacts that affect the Active contour algorithm. There are a total of four images with bad arc length estimation out of our dataset of 600 images
