this article reports the development and experimental analysis of an Urdu Optical Character REcognition (OCR) system. The proposed approach presents the preprocessing, features extraction and classification of Urdu language text. Three different features extraction techniques, the Hu moments, Zernike moments and the Principal Component Analysis (PCA) are used. Decision Tree algorithm J-48 is used...
This paper discusses the potential of the EEG signal for implementation of a practical biometric system using 4 or less channels of 2 different types of EEG recordings. Studies have shown that the EEG signal has biometric potential because the signal varies from person to person and is impossible to replicate and steal. Data were collected from 10 male subjects while resting with eyes open and eyes...
With the advent of the Internet, search engines were developed for English language because English language was a lingua franca. Currently, most of popular search engines such as Google and Yahoo! are available in more than 50 languages. However, these search engines have received less attention in South Asian languages especially, Urdu language. In this paper, we propose a novel approach for feature...
The paper presents a new approach for content based retrieval of images. The algorithm uses information sampled from around detected corner points in the image. A corner detection approach based on line intersections has been employed using Hough transform for line detection and then finding intersecting, near intersecting or complex shaped corners. As the affine transformations preserve the co-linearity...
Protein sequence analysis is an important task in bioinformatics. The classification of protein sequences into groups is beneficial for further analysis of the structures and roles of a particular group of protein in biological process. It also allows an unknown or newly found sequence to be identified by comparing it with protein groups that have already been studied. In this paper, we present the...
This paper presents a novel approach based on one of the signal processing tools in soft computing applied to Web information retrieval, namely wavelet transform. The influence of two parameters, wavelet functions (Mother wavelets) and decomposition level, on feature extraction and information retrieval ability of calibration model was investigated. The experimental results show that the proposed...
This paper presents a new technique for corner shape based object retrieval from a database. The proposed feature matrix consists of values obtained through a neighborhood operation of detected corners. This result in a significant small size feature matrix compared to the algorithms using color features and thus is computationally very efficient. The corners have been extracted by finding the intersections...
Recently, the problem of map building and simultaneous localization is a hot topic in mobile robotics field In this paper, a feature map building approach based on shape similarity for the development of home robot is presented In the map building process, the robot is continuously localized as the map is being built. The odometry error between each constitutive step is eliminated by comparing the...
