Performance comparison of classification algorithms for EEG-based remote epileptic seizure detection in wireless sensor networks by Abualsaud, Khalid, Mahmuddin, Massudi, Saleh, Mohammad, Mohamed, Amr

“…Identification of epileptic seizure remotely by analyzing the electroencephalography (EEG) signal is very important for scalable sensor-based health systems.Classification is the most important technique for wide-ranging applications to categorize the items according to its features with respect to predefined set of classes.In this paper, we conduct a performance evaluation based on the noiseless and noisy EEG-based epileptic seizure data using various classification algorithms including BayesNet, DecisionTable, IBK, J48/C4.5, and VFI.The reconstructed and noisy EEG data are decomposed with discrete cosine transform into several sub-bands.In addition, some of statistical features are extracted from the wavelet coefficients to represent the whole EEG data inputs into the classifiers.Benchmark on widely used dataset is utilized for automatic epileptic seizure detection including both normal and epileptic EEG datasets.The classification accuracy results confirm that the selected classifiers have greater potentiality to identify the noisy epileptic disorders.…”

Disparity map calculation through epipolar lines estimation for 3D facial reconstruction by Cheddad, Abbas, Setan, Halim, Majid, Zulkepli

“…The generated 3D model is developed to be the main input for Medical imaging tasks, although the model can be exploited in other fields as well. The algorithm is decomposed into two phases. The first phase deals with the location and extraction of human face from its cluttered background, this process is to focus on the region of interest (ROI) and to lessen down the computational burden. …”

Reconstruction of Arabic calligraphy by using Wang-Ball curves / Noorehan Awang ... [et al.] by Awang, Noorehan, Mohd Zauri, Aida Safiya, Jamil, Nur Fardila, Ghazalir, Fatin Najihah

“…Rational Wang-ball which is derived from non-rational Wang-ball curves, where it has been proven that a rational Wang-ball curve is a rational Bezier curve of the same degree and vice versa. A recursive algorithm for plotting rational Bezier and Wang-ball is obtained by the de Casteljau and Wang algorithm using homogeneous coordinates and an efficient algorithm for evaluating a rational Wang-ball curve is attained and has a linear time complexity (Dejdumrong et al., 2001). …”

A brief review on vessel extraction and tracking methods by Boroujeni, Farsad Zamani, Jahangard, Simindokht, O. K. Rahmat, Rahmita Wirza

“…This step is usually performed by enhancing vessel-like objects in the image, in order to differentiate between blood vessels and background, followed by applying the thinning algorithm to obtain the final output. Another approach is direct extraction of centerline points using exploratory tracing algorithm preceded by a seed point detection schema to provide a set of reliable starting points for the tracing algorithm. …”
