Description: The Billboard sample illustrates the billboarding technique. Rather than
rendering complex 3D models (such as a high-polygon tree model),
billboarding renders a 2D image of the model and rotates it to always face
the eyepoint. This technique is commonly used to render trees, clouds,
smoke, explosions, and more. For more information, see

-Medical image visualization technologies build 3D models with 2D medical image series to provide useful and precise information for the doctors. It is one of the crucial technologies in CAS system, Image Guide Surgery and Minimal Invasive Surgery. VTK is an advanced toolkit for the medical 3D visualization. DICOM is the international standards in the medical digital imaging and the data communicating, it unifies the formats of the medical image. In this paper, the VTK data-processing mechanism is outlined firstly, then VTK significant characteristics and common procedures model are introduced Secondly, the correct interpretation way of the DICOM images is brought forward. Three-dimensional reconstruction of the visual procedures is developed with VC++ and VTK, then implements some functions Finally, A medical 3D visualization analyzing laboratorial system is developed based on VTK in Windows.

Description: Active Contour (or Snake) Model is recognized as one of the efficient tools for 2D/3D image segmentation. How- ever, traditional snake models prove to be limited in sev- eral aspects. The presentpaper describes a set of difision equations applied ro image gradient vectors, yielding a vec- torfeld over the image domain. The obtained vectorfield pmvides the Snake Model an exrernal force as well as an auromatic way to generate the initial contours. Finally a region merging technique is employed to further impmve the segmentation results. Platform: |

Description: 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 problem as the motion is in three dimensions but the images are a projection of the 3D scene onto a 2D plane. The motion vectors may relate to the whole image (global motion estimation) or specific parts, such as rectangular blocks, arbitrary shaped patches or even per pixel. The motion vectors may be represented by a translational model or many other models that can approximate the motion of a real video camera, such as rotation and translation in all three dimensions and zoom.-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.

Description: 医学图像配准，医学图像2D_3D配准，基于vc++开发。-Abstract. We present a method that performs the rigid 2D/3D image registration
efficiently on the GPU. As one main contribution of this paper, we propose an
efficient method for generating realistic DRRs that are visually similar to X-ray
images. Therefore, we model some of the electronic post-processes of current X-
ray C-arm-systems. As another main contribution, the GPU is used to compute
eight intensity-based similarity measures between the DRR and the X-ray image
in parallel. A combination of these eight similarity measures is used as a new
similarity measure for the optimization. We evaluated the performance and the
precision of our 2D/3D image registration algorithm using two phantom models.
Compared to a CPU+GPU algorithm, which calculates the similarity measures
on the CPU, our GPU algorithm is between three and six times faster. In contrast
to single similarity measures, our new similarity measure achieved precise and
robust registration results for both phantom m Platform: |
