Augmented Reality (AR) is an emerging field, which is evolving exponentially. Its concept is to coalesce the virtual world into the real world. The augmented reality intent to enhance our perception of the real world by integrating virtual objects. The existing Augmented Reality Hand gesture control systems detect hand gesture and embed the virtual object in augmented reality using markers and motion...
Accurate motion capture and flexible retargeting of underwater creatures such as fish remain to be difficult due to the long-lasting challenges of marker attachment and feature description for soft bodies in the underwater environment. Despite limited new research progresses appeared in recent years, the fish motion retargeting with a desirable motion pattern in real-time remains elusive. Strongly...
The technology for detection of indoor location information has been attracting much attention in the recent past, since such information can be utilized for navigation and marketing research. The commonly used indoor location detection methods are Wi-Fi positioning, Bluetooth Low Energy (BLE) beacons and Pedestrian Dead-reckoning (PDR). PDR can provide location information relative to the original...
This paper is a combined method for stereo matching. Between the stereo images have difference perspective each other. The difference of stereo images is called disparity. This information measures the difference of reference and target stereo images. Then we can estimate the correspondence points on the target image from reference image. The proposed method is a combination of SIFT and cost aggregation...
An optical camera was recently employed by a subset of the authors as a sensing modality complementary to that of a Pyroelectric InfraRed (PIR) sensor, for carrying out intrusion detection and classification in an outdoor environment. The aim there was to develop a classification algorithm that mimicked the performance of the PIR sensor and which was complementary to the PIR in the sense that it could...
Use of camera has increased among professionals and nonprofessionals in recent years and videos are being captured widely and wildly for information, knowledge, surveillance, adventures and memories. So these videos are highly vulnerable to suffer from translational and rotational noises. These noise are caused by multiple factors and it is difficult to remove all those causes. So digital video stabilization...
This paper presents our research on indoor location estimation based on the identity of floor surface patterns, which we call “floor fingerprints,” calculated from a photographic image of the floor taken by a user. Because floor textures generally appear to lack sufficient detail concerning surface features, it may seem impossible for general feature detection algorithms to find matching pairs of...
Experiments play a vital role in science education. In high school physics, especially in mechanics, many experiments are conducted where tracking a single or multiple objects are required. In most situations students visually observe the motion of objects and take the measurements. This manual method is time consuming, generates higher error and incapable of producing multiple readings rapidly. The...
The increase in the number of elderly motivates academic researchers to develop technologies that can ensure self-sufficiency in their lives. In this research, prototype of an inexpensive video monitoring system for the elderly using a single RGB camera proposed. In the process is divided into two, namely vision and event recognition module. For event recognition, we use a hierarchical description-based...
In this paper, we propose a novel approach for an automatic aerial image georeferencing for an unmanned aerial vehicle (UAV) image data acquisition platform that does not require the use of ground control points (GCPs). The determination of GCPs is, in general, a costly and slow process, hence a considerable bottleneck in georeferencing. With predefined route planning and making a mosaic of acquired...
This paper presents a novel technique for face recognition based on facial landmarks extracted automatically. Our landmarks are those associated with eyes mouth and nose. With the extracted landmarks, the area triplets and the associated geometric invariance are formed. We opt to use area and triangle confined within the triangle as the invariance. To bypass the perspective constraints, we take the...
This paper presents the current state of a novel event-based surveillance framework for real-time detection and tracking of the person-of-interest with IP PTZ network camera. Formulating the problem in a (non-linear) Bayesian filtering framework in combination with Convolutional Neural Networks (CNN), we develop dynamical and adaptive approaches for identifying the Person-of-Interest(PoI) from its...
Segmentation process in an essential part in image processing to obtain good preparation either for further process of data mining or object recognition. This paper proposes a new method of segmenting tomato image for clustering its ripeness. The tomato images are taken from three types of smartphone camera in various lighting condition with white background. When taking picture by using smartphone...
In this work, the problem of video orchestration performed by combining information extracted by multiple video sequences is considered. The novelty of the proposed approach relies on the use of aesthetic features and of cinematographic composition rules for automatically aggregating the inputs from different cameras in a unique video. While prior methodologies have separately addressed the issues...
Real-time image processing on low cost embedded systems is still a challenging research area. For this embedded platform, there is a trade-off between accuracy and processing time. We proposed a pedestrian detection method for thermal images that can perform in real-time on a Raspberry Pi embedded system while still keeping the accuracy high. Our detection framework is based on the conventional HOG-based...
This paper presents a novel background subtraction method that is flexible for various background scenarios. The method includes automated-directional masking (ADM) algorithm for adaptive background modeling and historical intensity pattern reference (HIPaR) algorithm for foreground segmentation. By selecting an appropriate mask in a set based on directional feature, ADM updates background smoothly...
The aversion of gaze during dyadic conversations is a social signal that contains information relevant to the detection of interest, turn-taking cues, and conversational engagement. The understanding and modeling of such behavior has implications for the design of embodied conversational agents, as well as computational approaches to conversational analysis. Recent approaches to extracting gaze directions...
Camera tamper detection is the ability to detect faults and operational failures in video surveillance cameras by analyzing the video. Researchers have increasingly focused on such techniques attributing to the ubiquitous deployment of large scale surveillance systems. In this paper, a signal detection theory approach is proposed to quantitatively analyze the information being captured by the camera...
Haar-Cascade classifier method has been applied to detect the presence of a human on the thermal image. The evaluation was done on the performance of detection, represented by its precision and recall values. The thermal camera images were varied to obtain comprehensive results, which covered the distance of the object from the camera, the angle of the camera to the object, the number of objects,...
Human action recognition is currently one of the hottest areas in pattern recognition and machine intelligence.
