This paper addresses the problem of 3D human pose estimation in the wild. A significant challenge is the lack of training data, i.e., 2D images of humans annotated with 3D poses. Such data is necessary to train state-of-the-art CNN architectures. Here, we propose a solution to generate a large set of photorealistic synthetic images of humans with 3D pose annotations. We introduce an image-based...

BACKGROUND Abdominal computed tomography (CT) is a frequently performed imaging procedure, resulting in considerable radiation doses to the patient population. Postprocessing filters are one of several dose reduction measures that might help to reduce radiation doses without loss of image quality. PURPOSE To assess and compare the effect of two- and three-dimensional (2D, 3D) non-linear adapt...

In this paper, we present a recognition method for a 3D object in scattering media by using the axially distributed sensing (ADS) method and nonlinear correlation operation. Since the scatter noise for a 3D object is recorded into the elemental images by ADS method, we apply a statistical image-processing algorithm to convert the scattering elemental images into the scatter-reduced ones. After ...

BACKGROUND Recently, multi-planar reconstruction of the three-dimensional (3D) spiral chest CT scan has demonstrated superiority in the evaluation of the tracheobronchial tree. The goal of this study was to measure the lengths of the right and left main bronchi and their anteroposterior (AP) and transverse (TR) diameters using the 3D and two-dimensional (2D) images in the same adult respectivel...

optical coherence tomography (oct) is a powerful imaging modality used to image various aspects of biological tissues, such as structural information, blood flow, elastic parameters, change of polarization states, and molecular content [1]. in contrast to oct technology development which has been a field of active research since 1991, oct image segmentation has only been more fully explored dur...

The Stereoscopic image provide information on details of each object in the image in three dimension and helps to observe the image in a better way. The Stereoscopic images are also called as 3D images. The 3D Digital Cameras, 3D Televisions, 3D Projectors etc. are commonly available in the electronic stores in a reasonable price. The people prefer 3D images than the 2D image. The 3D image prov...

We present a method for animating 3D models of animals from existing live video sequences such as wild life documentaries. Videos are first segmented into binary images on which Principal Component Analysis (PCA) is applied. The time-varying coordinates of the images in the PCA space are then used to generate 3D animation. This is done through interpolation with Radial Basis Functions (RBF) of ...

Three-dimensional (3D) imaging techniques have been developed in the medical field. In laparoscopic surgery, such techniques are widely used; they provide the surgeon with spatial information and increase the safety of surgical techniques [1–3]. In gastrointestinal endoscopy, Sakata et al. reported the efficacy of 3D imaging for improved detection of colonic lesions using simulated 3D colonosco...
