The 3D shape reconstruction, from 2D images is an converse problem, and is therefore mathematically poorly posed. The solution to 3D shape reconstruction problem is to using a model based approach. Our paper presents an analysis by synthesis method for solving3D face reconstruction problems, using the anatomical landmarks and intensity from 2D frontal face images. To improve the quality of 3D s...

In this paper, we focus on the real-time 3D shape reconstruction of an object moving in a wide area(e.g. a dancing human). To efficiently record dynamically changing 3D object shape, the real-time 3D shape reconstruction and active tracking are required. For the real-time 3D shape reconstruction, we propose a parallel plane-based volume intersection method. By implementing the algorithm on a PC...

This paper presents a 3-D reconstruction method IBM(image based modeling) of an image that does not contain any camera information. This system adopts a 3D reconstruction method based on a model. Model-based 3D reconstruction recovers an image using the geometric characteristics of a predefined polyhedron model. It uses a pre-defined polyhedron model as the primitive and the 3D reconstruction i...

3d reconstruction from a single image is inherently an ambiguous problem. Yet when we look at a picture, we can often infer 3d information about the scene. Humans perform single-image 3d reconstructions by using a variety of singleimage depth cues, for example, by recognizing objects and surfaces, and reasoning about how these surfaces are connected to each other. In this paper, we focus on the...

To show the three-dimensional (3D) shape of a live toad embryo is helpful to understand the toad embryo development. It is also desired to make more details visible by using high magnification objective lens. However, limited depth-of-field and field-of-view make it challenging to use high magnification objective lens in imaging the embryo development. This paper shows that 3D reconstruction of...

The relief of the seafloor is an important source of data for many scientists. In this paper we present an optical system to deal with underwater 3D reconstruction. This system is formed by three cameras that take images synchronously in a constant frame rate scheme. We use the images taken by these cameras to compute dense 3D reconstructions. We use Bundle Adjustment to estimate the motion of ...

This paper focuses on how the accuracy of marker-less human motion capture is affected by the number of camera views used. Specifically, we compare the 3D reconstructions calculated from single and multiple cameras. We perform our experiments on data consisting of video from multiple cameras synchronized with ground truth 3D motion, obtained from a motion capture session with a professional foo...

In this paper, we target enhanced 3D reconstruction of non-rigidly deforming objects based on a view-independent surface representation with an automated recursive filtering scheme. This work improves upon the KinectDeform algorithm which we recently proposed. KinectDeform uses an implicit viewdependent volumetric truncated signed distance function (TSDF) based surface representation. The view-...

3D reconstruction from visual hulls is a well established technique for camera based reconstruction of 3D objects in computer graphics. We propose in this paper to employ visual hull techniques to quantify the volume of diffusely defined gaseous structures. In our evaluation, visual quality of the 3D reconstructions is secondary. Instead, using synthetic ground truth data, we determine the numb...

3D reconstruction pipelines using structure-from-motion and multi-view stereo techniques are today able to reconstruct impressive, large-scale geometry models from images but do not yield textured results. Current texture creation methods are unable to handle the complexity and scale of these models. We therefore present the first comprehensive texturing framework for large-scale, real-world 3D...
