In this tutorial, we discuss a broad range of classical solutions as well as the emerging approaches based computational cameras/videos. This is the basic tutorial for TrakEM2. Structure-from-Motion (SfM) is the process of reconstructing 3D structure from its projections into a series of images. One of the most diverse data sources for modeling is Internet photo collections. If so how to correct it? The essence of an image is a projection from a 3D scene onto a 2D plane, during which process the depth is lost. We used Samsung Galaxy camera, which captures images that are 4608 pixels wide and 3456 pixels high; and videos that are 1920x1080. There are also many methods for image processing in brain. Also by solving the problem of dense 3D reconstruction and class segmentation jointly, prior knowledge such as the ground is usually a surface which is close to horizontal can be included.
