vector_angle_to_rigidcomputes a rigid affine transformation, i.e., a transformation consisting of a rotation and a translation, from a point correspondence and two corresponding angles and returns it as the homogeneous transformation matrixHomMat2D. The matrix consists of 2 components: a rotation ma...

stretching, and twisting all are transformations of the ball. In geometry, atransformationis a function applied to a geometric object. Some transformations preserve the shape of an object, but other transformations alter the shape of the object. So, which transformations preserve the shape of an ...
vector_to_rigidapproximates a rigid affine transformation, i.e., a transformation consisting of a rotation and a translation, from at least two point correspondences and returns it as the homogeneous transformation matrixHomMat2D. The matrix consists of 2 components: a rotation matrix R and a tra...
Instead of computing a global affine transformation, we attach to each point a local affine transformation varying smoothly along the surface. We call this deformation a locally affine deformation. All these stages are illustrated with experiments on various real biomedical surfaces (teeth, faces, ...
affine transformation between two surfaces. We introduce differential informations in points coordinates: this allows us to match locally similar points. We show how this differential information is transformed by an affine transformation. Finally, we introduce curvatures in the best affine transformation ...
用得最多的线性变形之一是就是仿射变换（请自行wiki: affine transformation），它能表达平移、旋转、缩放...
In rigid and affine transformations, there exist a uniform transformation between the two images to be registered. Another common type of transformation found between medical images is non-rigid transformation [43] [44] where, non-uniform mapping is found between the pixels/voxels of two medical ...
3. Rigid Transformation of the Coordinate System An affine transformation is a transformation model of a two-dimensional plane coordinate system to another two-dimensional plane coordinate system [24]. When the objects in the two coordinate systems only have rotation and translation transformations, it...
