To retrieve higher meaning from images there are often a number of preliminary tasks that need to be performed. Image registration and segmentation are two important processes that fall into this category. In this seminar I will present a new approach for registration of a 3D object with a 2D image of the same or a similar object and a new approach for segmentation of images based on texture. The new 2D-3D registration algorithm uses a similarity measure that is inherently robust to variations in intensity between the 2D and 3D objects and therefore can be used to register images of objects captured using different sensors. The new texture segmentation algorithm is based on features derived from the dual-tree complex wavelet transform of the image and is able to perform segmentation that is invariant to the scale and rotation of the texture in the image regions.
