3D Gaussian Descriptor for Video-based Person Re-Identification

Despite being often considered less challenging than image-based person re-identification (re-id), video-based person re-id is still appealing as it mimics a more realistic scenario owing to the availability of pedestrian sequences from surveillance cameras. In order to exploit the temporal infor...

Alignment of Point Clouds for Comparison of Infrastructures in Civil Engineering on Quality Control in Metrology

For 3D point cloud registration, Go-ICP [Yang et al., 2016] has been shown to obtain the global optimal solution for a pair composed of a model point cloud and a data point cloud. Go-ICP mostly has been investigated only on standard sets of point clouds. In this ...

The City Metaphor in Software Visualization

A city metaphor has become a popular method of visualizing properties of program code. This paper provides an overview of research projects that employ this metaphor for a wide range of software engineering tasks. Until now, projects employing the city metaphor have primarily focus...

Compressed Exposure Sequences for HDR Imaging

High dynamic range (HDR) imaging techniques allow photographers to capture the luminance distribution in the real-world as it is, freeing them from the limitations of capture and display devices. One common approach for creating HDR images is the multiple exposures technique (MET). This...

Automated Object Tracking in Sterile Pharmacy

A new method to automatically track objects in the process of sterile pharmacy compounding is introduced. The method performs the automatic object tracking by applying a simple object detection followed by an object tracking algorithm. The advantages of the method are that it enabl...

Performance Evaluation and Comparison of Service-based Image Processing based on Software Rendering

This paper presents an approach and performance evaluation of performing service-based image processing using software rendering implemented using Mesa3D. Due to recent advances in cloud computing technology (w.r.t. both, hardware and software) as well as increased demands of image processing and...

Collateral effects of the Kalman Filter on the Throughput of a Head-Tracker for Mobile Devices

We have developed an image-based head-tracker interface for mobile devices that uses the information of the front camera to detect and track the user’s nose position and translate its movements into a pointing metaphor to the device. However, as already noted in the literature,...

Pi-surfaces: products of implicit surfaces towards constructive composition of 3D objects

Implicit functions provide a fundamental basis to model 3D objects, no matter they are rigid or deformable, in computer graphics and geometric modeling. This paper introduces a new constructive scheme of implicitly-defined 3D objects based on products of implicit functions. This scheme ...

Straight Skeleton Computation Optimized for Roof Model Generation

3D building models with roofs are important in several fields, such as urban planning and BIM (Building Information Model). However, enormous time and labor are required to create these 3D models. In order to automate laborious steps, a GIS and CG integrated system is proposed...

Corotated meshless implicit dynamics for deformable bodies

This paper proposes a fast, stable and accurate meshless method to simulate geometrically non-linear elastic behaviors. To address the inherent limitations of finite element (FE) models, the discretization of the domain is simplified by removing the need to create polyhedral elements. The&#x...

Dynamic Radiosity

In this paper we propose a novel radiosity implementation which we called dynamic radiosity. By storing and updating local form-factor matrix of the patches closest to the observer we have solved 2 main problems of radiosity algorithm: (1) quadratic complexity of the algorithm and&...

Anatomy-Focused Volume Line Integral Convolution for Brain White Matter Visualization

3D visualization of volumetric line integral convolution (LIC) datasets has been a field of constant research. So far, most approaches have focused on finding suitable transfer functions and defining appropriate clipping strategies in order to solve the problem of occlusion. In medicine,...

Analyzing pixel spread correlation with lenticular lens efficiency on multi user VR displays

One of the all time issues with Virtual Reality systems regardless if they are head-mounted or projection based is that they can only provide perspective correctness to one user. Such limitation affects collaborative work which is nowadays the standard anywhere. One of the approach...

Evaluation of 4D Light Field Compression Methods

Light field data records the amount of light at multiple points in space, captured e.g. by an array of cameras or by a light-field camera that uses microlenses. Since the storage and transmission requirements for such data are tremendous, compression techniques for light fields...

SyCaT-Vis: Visualization-Based Support of Analyzing System Behavior based on System Call Traces

Detecting anomalies in the behavior of a computer system is crucial for determining its security. One way of detecting these anomalies is based on the assessment of the amount and sequence of system calls issued by processes. While the number of processes on a computer ca...

Stylized Sketch Generation using Convolutional Networks

The task of synthesizing sketches from photographs has been pursued with image processing methods and supervised learning based approaches. The former lack flexibility and the latter require large quantities of ground-truth data which is hard to obtain because of the manual effort requi...

Performance Assessment of Convolutional Neural Networks for Semantic Image Segmentation

Convolutional neural networks are applied successfully for image classification and object detection. Recently, they have been adopted to semantic segmentation tasks and several new network architectures have been proposed. With respect to automotive applications, the Cityscapes dataset is often used&...

Deep Learning-based Overlapping-Pigs Separation by Balancing Accuracy and Execution Time

The crowded environment of a pig farm is highly vulnerable to the spread of infectious diseases such as foot-andmouth disease, and studies have been conducted to automatically analyze behavior of pigs in a crowded pig farm through a video surveillance system using a top-view c...

Cubic Spline Interpolation in Real-Time Applications using Three Control Points

Spline interpolation is widely used in many different applications like computer graphics, animations and robotics. Many of these applications are run in real-time with constraints on computational complexity, thus fueling the need for computational inexpensive, real-time, continuous and loop-free dat...
