Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another; usually from adjacent frames in a video sequence. It is an ill-posed ...

One challenge of using a projection matrix is that it changes the dimensionality of the points from 3D to 2D. To avoid this problem, you can use homogeneous coordinates, which are a way of ...

Maximum Intensity Projection is a common tool to represent 3D biological imaging data in a 2D space, but it creates artefacts. Here the authors develop Smooth Manifold Extraction, an ImageJ/Fiji ...

Abstract: Reconstructing an arbitrary configuration of 3D points from their projection in an image is an ill-posed problem. When the points hold semantic meaning, such as anatomical landmarks on a ...

Nowadays, leveraging 2D images and pre-trained mod- els to guide 3D point cloud feature representation has shown a remarkable potential to boost the performance of 3D fundamental models. While some ...
