Automatic license plate detection (ALPD) is one of the widespread research topics in the area of intelligent transportation systems. A challenging issue that affects ALPD performance is the complex image background, where possibility of ...

The increasing incidence of melanoma has led to development of computer-aided diagnosis systems that classify dermoscopic images. A fundamental problem however during the pre-processing stage is the removal of artifacts such as hair. Hair strands ...

This paper presents an approach of structure-preserving image completion with dynamic patches. Existing image completion methods may generate unnatural abnormal structures or structure disorders due to limited patches and patterns availability. Our ...

Image analysis has an application in diverse fields. The objective of this paper is to use the image analysis for the computation of Land-Use and Land-Cover (LULC) around the schools. The assessment of vicinity of schools is very useful. This data can ...

This paper proposes an age progression method for facial videos. Age is one of the main factors that changes the appearance of the face, due to the associated sagging, spots, and wrinkles. These aging features change in appearance depending on facial ...

In the application of 3D object retrieval we search for 3D objects similar to a given query object. When a user searches for a certain class of objects like 'planes' the results can be unsatisfying: Many object variations are possible for a single class ...

In 3D object retrieval, additional knowledge like user input, classification information or database dependent configured parameters are rarely available in real scenarios. For example, meta data about 3D objects is seldom if the objects are not within ...

As the scale of 3D model databases increase, speed, in addition to accuracy, of its search becomes very important. One way to achieve fast search is to use a compact 3D shape feature whose cost of comparison is very small. Binarization of a real-valued ...

We present a novel statistical shape descriptor for arbitrary three-dimensional shapes as a six-dimensional feature for generic classification purposes. Our feature parameterizes the complete geo-metrical relation of the global shape and additionally ...

In this paper, we propose a new and simple method for filling complex holes in surfaces. To fill a hole, locally uniform points are added to the hole by creating contour curves inside the boundary edges of the hole. A set of contour curves is created by ...

Physically-based fluid animation and solid deformation driven by numerical simulation have manifested their significance for many graphics applications during the past two decades. For example, the fluid implicit particle (FLIP) method and shape ...

It has been very significant to visualize time series big data. In the paper we shall discuss design on time series statistical data. As an example, we present an animation of Gibbs sampling process to clarify the time changes. Gibbs sampling is widely ...

Functional magnetic resonance imaging (fMRI) is a 4D medical imaging modality that depicts a proxy of neuronal activity in a series of temporal scans. Statistical processing of the modality shows promise in uncovering insights about the functioning of ...

Astronomers have been observing blazars to solve the mystery of the relativistic jet. A technique called TimeTubes uses a 3D volumetric tube to visualize the time-dependent multivariate observed datasets and allows astronomers to interactively analyze ...

In our turbine performance assessment, we need to provide an effective visual analytics tool in handling high-dimensional datasets. We have employed RadViz in 2D exploratory data analysis. However, with the increase of dataset size and dimensionality, ...

We¹ often want to track back the conversation logs, such as meeting or group chats which users were late to participate, and timelines of social network services. It often happens to be difficult to find important remarks if the logs are very long. ...

In the last few years, Electronic Health Records (EHRs) have collected large-sized medical data. While EHR allows doctors to approach medication data easily, they suffer difficulties to analyze multi-dimensional medical data. We present multi-...

We propose a novel approach to assisting users with searching the optimal composition of a photograph. In existing studies, the process of detecting the object in a given photo occurred via only image processing, however the result does not always ...

Yamato-e and Ukiyo-e style are Japanese traditional painting styles that have two characteristics, linearity and verticality. We propose a novel generalized projection method to produce such images using 3D computer graphics. The method enables ...

Volume rendering is an effective method for visualizing 3D data. However, it's still difficult to obtain an effective image, especially when there are complicated structures which may cause underexposure problems. Adjusting light sources and parameters ...

Stereo and head tracking are considered as distance perception cues in virtual environments. Several studies have investigated their influence on several tasks. Results were different among studies. In this paper, we conducted a complete experiment ...

Redirected walking, a technique in which the user's orientation in the physical space is constantly and imperceptibly changed from their orientation in the virtual world, has been shown to be an effective technique when only a limited physical space is ...

Haptic feedback has always been a missing link in online shopping. In this project, we study whether a commonly-used haptic device with only one Haptic Interface Point (HIP) can be used in online shopping for compensating lack of physical touch. A user ...

Recent developments in 3D scanning make it easy to obtain 3D geometry of a human and produce a 3D replica using a 3D printer. However, the setting for full body scanning enforces low-quality of the facial area due to the lack of image resolution. To ...

We propose a new corner estimation technique for 3D point cloud on convex polyhedral surfaces acquired by a 3D scanner. A corner is an important property of objects, and it is used in various technologies such as 2D or 3D object recognition system. The ...

Currently, hair geometry is mostly represented as sequences of 3D points. It is difficult to simulate hair directly from this representation. This paper proposes a novel approach to convert hair geometry model into helices, which could be easily plugged ...

The use of cost-efficient and portative devices, such as the Ki-nect, has facilitated the reconstruction of indoor scenes, which has become a field of interest to many. While a large number of applications have been developed for the accurate ...

In this paper, we propose a modeling method of clouds from a single photograph. To synthesize realistic images of outdoor scenes, modeling of 3D clouds is necessary. However, synthesizing realistic clouds is still a difficult task. To address this ...
