The two-volume set LNCS 10269 and 10270 constitutes the refereed proceedings of the 20th Scandinavian Conference on Image Analysis, SCIA 2017, held in Tromso, Norway, in June 2017. The 87 revised papers presented were carefully reviewed and selected from 133 submissions. The contributions are structured in topical sections on history of SCIA; motion analysis and 3D vision; pattern detection and recognition; machine learning; image processing and applications; feature extraction and segmentation; remote sensing; medical and biomedical image analysis; faces, gestures and multispectral analysis.

The relationship between static and dynamic occlusion is one of the aspect of study of functional occlusion.Orthodontic treatment has the capacity to change static and functional occlusion. It is assumed that ideal static occlusion is compatible with ideal functional occlusion but it is not necessary.It has traditionally been assumed in orthodontics that correction of the parts of the dentofacial complex to an anatomical norm along with a class I relationship of the buccal segments and alignment of teeth would yield a "good functional occlusion" that is in harmony with temperomandibular joints and associated musculature. The question is: " Can we, or should we accept this assumption as true?" As valuable as our anatomical guidelines and parameters may be in diagnosis and treatment planning, we should assess the function of the occlusion we treat orthodontically, both prior to and after treatment
