Interference Management (IM) is one of the major challenges of next generation wireless communication. Fractional Frequency Reuse (FFR) has been acknowledged as an efficient IM technique, which offers significant capacity enhancement and improve cell edge coverage with low complexity. In literature, FFR has been analyzed mostly with cellular networks described by Hexagon Grid Model, which is neither...
A multi-agent robot system can speed up exploration or search and rescue operations in dangerous environments by working as a distributed sensor network. Each robot (e.g. Eddi Robot) equipped with a combined 2D/3D sensor (MS Kinect) and additional sensors needs to efficiently exchange its collected data with the other group members for task planning. For environment perception a 2D/3D panorama is...
This paper presents a natural feature tracking system for object recognition in real-life environments. The system is based on a local keypoint descriptor method optimized and adapted to extract salient regions within the image. Each object in the gallery is characterized by keypoints and corresponding local descriptors. The method first identifies gallery object features in new images using nearest...
Face detection and segmentation is an important prerequisite step for many face related processes such as face recognition and facial expression recognition. A method that automatically segments the given faces images irrespective of their different sizes and orientations will not only ease the subsequent face analysis task but will as well enhances its performance. In this work, an adaptive radius...
This paper presents a proposal of a method to estimate a light environment using a single image of cylinder as a calibration object with a Lambertian surface. The light environment to be estimated is modeled as a single light source with size and an ambient light. The proposed method estimates the model parameter directly from pixel values of a single cylinder image. Experimental results demonstrate...
Yawn is one of the common fatigue sign phenomena. The common technique to detect yawn is based upon the measurement of mouth opening. However, the spontaneous human action to cover the mouth during yawn can prevent such measurements. This paper presents a new technique to detect the covered mouth by employing the Local Binary Pattern (LBP) features. Subsequently, the facial distortions during the...
This paper presents an alternative approach for Content Based Image Retrieval (CBIR) using Scale Invariant Feature Transform (SIFT) algorithm for binary and gray scale images. The motivation to use SIFT algorithm for CBIR is due to the fact that SIFT is invariant to scale, rotation and translation as well as partially invariant to affine distortion and illumination changes. Inspired by these facts,...
Fractal image compressions of Standard Lena and Satellite imageries have been carried out for the variable size range block method. The image is partitioned by considering maximum and minimum size of the range block and matching it with the domain block. The domain block size of window K*K are sliding over the entire image in steps of K/2. Affine transformation and entropy coding are applied to achieve...
One of the common form of representing stereoscopic video is combination of 2D video with its corresponding depth map which is made by a laser camera to illustrate depth in the video. When this type of video is transmitted over error prone channels, the packet loss leads to frame loss; and mostly this frame lost occur in depth frames. Thus, a depth error concealment based on decision making termed...
Selamat Datang (Welcome!) to the 2013 IEEE International Conference on Signal and Image Processing Applications or more fondly known as IEEE ICSIPA 2013. As the 3rd in the series, this flagship conference of the IEEE Signal Processing Society (Malaysia) (awarded Best Signal Processing Chapter 2011) has a good reputation for quality and a forum for valuable exchange of knowledge. It gains participation...
Silicone photomultiplier (SiPM) technology have been introduced recently for photons detection. This type of detector offer various advantages compare to the conventional photomultiplier tubes (PMTs). SiPM are smaller in size and thus consumes less space. Several researches have been conducted using SiPM for image acquisition in the field of medical imaging. The aim of this research is to model the...
In some applications, multivariable stochastic processes that are composed of sequentially arranged independent weakly-stationary processes, may arise. Such multivariable process can be categorized as a class of non-summable processes with very complex probability density function. In this paper, we present the formal definition of such non-summable process, and provide a method of parameterizing...
We present a fast and efficient method for feature-based synthesis of musical sounds that are perceptually close to an actual instrument, by designing filters that spectrally shape a chosen excitation signal. We have proposed a novel, multi-dimensional set of features for the Indian bamboo flute which has been used for the filter design. The filter design approach aims at providing a generic framework...
Iris recognition is the most accurate biometric identification system on hand. Most iris recognition systems use algorithms developed by Daugman. The performance of iris recognition is highly depends on edge detection. Canny is the edge detectors which commonly used. The objectives of this research are to a) study the edge detection criteria and b) measure the PSNR values in estimating the noise between...
The main problem associated with 3D video delivery is huge data transmission rate especially when the data to be submitted are large video files such as multiview plus depth videos. This paper describes a new method of compression for multiview videos with depth data by using the new High Efficiency Video Coding (HEVC) technology. We propose a new compression method by applying the Reduced Resolution...
A face detection system is a computer application for automatically detecting a human face from digital image or video frame. This paper presents a face detection system that used web camera to detect and track a face in real-time. To detect a face in the image, a simple method of skin color detection is used. By using color detection method in this project, the face can be segmented easily from the...
There has been extensive discussions on the performance of the LMS algorithm in nonstationary environment. In some instances its performance in such environments has been compared with that of other adaptive algorithms. However, most existing works treated in this respect focus on narrowband channels. In this paper, we investigate the performance of the LMS, NLMS and LMF algorithms in tracking time-varying...
