3D Convolutional Neural Networks for Human Action Recognition

Wed, 18 Aug 2010 06:53:20 -0700

The paper considers the fully automated recognition of actions in uncontrolled environment. Most existing work relies on domain knowledge to construct complex handcrafted features from inputs. In addition, the environments are usually assumed to be controlled. Convolutional Neural Networks (CNNs) are a type of deep models that can act directly on the raw inputs, thus automating the process of feature construction. However, such models are currently limited to handle 2D inputs. This paper develops a novel 3D CNN model for action recognition. This model extracts features from both spatial and temporal dimensions by performing 3D convolutions, thereby capturing the motion information encoded in multiple adjacent frames.

A Geoscience Perspective on Immersive 3D Gridded Data Visualization

Tue, 27 Jul 2010 03:02:07 -0700

The authors describe visualization software, Visualizer that was developed specifically for interactive, visual exploration in immersive Virtual Reality (VR) environments. Visualized uses carefully optimized algorithms and data structures to support the high frame rates required for immersion and the real-time feedback required for interactivity. As an application developed for VR from the ground up, Visualizer realizes benefits that usually cannot be achieved by software initially developed for the desktop and later ported to VR. However, Visualizer can also be used on desktop systems with a similar level of real-time interactivity, bridging the "Software gap" between desktop and VR that has been an obstacle for the adoption of VR methods in the Geosciences.

Data Acquisition and Quality Analysis of 3-Dimensional Fingerprints

Mon, 19 Jul 2010 05:34:16 -0700

This paper introduces a new technology of non-contact 3D fingerprint capture and processing for higher quality fingerprint data acquisition. The system relies on a real-time 3D sensor using Structured Light Illumination (SLI), which generates both texture and detailed ridge depth information. The high resolution 3D scans are then converted into 2D flat equivalent fingerprints. As a result, many limitations imposed upon conventional fingerprint capture and processing can be reduced by the unobtrusiveness of this approach and the extra depth information acquired. The image quality of 2D flat equivalent fingerprint is evaluated and analyzed using NIST fingerprint image software. A comparison is performed between the unraveled 3D fingerprints and their 2D plain counterparts in terms of fingerprint quality.

A Low Cost 3D CAD Model Visualization Interface for Manufacturing Industries

Mon, 28 Jun 2010 05:28:38 -0700

It is the dream of all manufacturing industries to possess a cost effective 3D CAD Model Visualization Interface. With this feature the industries aim to manipulate the models in totality and facilitate productivity. The challenges faced by manufacturing industries center around reduced efficiency, inoperability, more time in product development cycle, and increased operational costs. With 3D CAD Model Visualization, they aim to solve this problem to a great extent. There are commercial products in the market that do the modeling job but each one comes with its own set of problems. They have high licensing fee, takes up a lot of computer storage space, and uses up a lot of memory. 3D models are usually of gigantic size owing to their geometric information. The software that is talked about in this informative paper is an interesting package that fulfills all the goals of the industries and more. The CAD software can be categorized into native file formats and standard file formats. But native file formats do not generally allow files of a different format. These files are readable, structured and easy to use. The language used in 3D exchange format files is called Virtual Reality Modeling Language (VRML). All these features combined with cost effectiveness, transparency, editing capabilities and other application features contributed to using this software. It helps manufacturing industries to go into the production stage with ease and enhanced production capabilities.

3D-Modeling by Ortho-Image Generation From Image Sequences

Mon, 28 Jun 2010 05:20:12 -0700

3-D Modeling is a special semi-automatic approach that aids in the documentation of facade structures. The high quality image can be taken from a moving, uncalibrated consumer and yet the image will remain static. Whatever the building or structure is divided into different plains and sub-plains. A bounding object is placed around different areas of the building or object and each of these areas are projected independently. Placing the bounding box is important. It should take into account all the camera parameters and work interactively with them. Depending on the quality of the surface orthographic projections are generated out of the image sequences. The 3-D model thus generated will be estimated according to the shape and silhouette approach of the object. The images thus generated are then imported as background maps which include the top, side and front view. The problems arise when one doesn't get a discernible image because details are lost and the image looks noisy. To overcome this situation, semi automatic systems were introduced and these work fine with a little bit of manual intervention. The result of the image thus generated is accurate and efficient. The paper presents the possibilities of different systems that are used in 3-D modeling and the advantages of using them. The conclusion can be reached that 3D images can be generated for not just solid surfaces, but it is possible to work with translucent surfaces.

Realtime Visualization of Monocular Data for 3D Reconstruction

Wed, 31 Mar 2010 23:53:38 -0700

Methods for reconstructing photorealistic 3D graphics models from images or video are appealing applications of computer vision. Such methods rely on good input image data, but the lack of user feedback during image acquisition often leads to incomplete or poorly sampled reconstruction results. This paper describe a video-based system that constructs and visualizes a coarse graphics model in real-time and automatically saves a set of images appropriate for later offline dense reconstruction. Visualization of the model during image acquisition allows the operator to interactively verify that an adequate set of input images has been collected for the modeling task, while automatic image selection keeps storage requirements to a minimum.
