Feature Extraction using Histogram of Oriented Gradients for Image Classification in Maize Leaf Diseases
The paper presents feature extraction methods and classification algorithms used to classify maize leaf disease images. From maize disease images, features are extracted and passed to the machine learning classification algorithm to identify the…
ENMSJ : An Efficiency Filtering Technique using Bitmap Vectors for n-way Joins in Wireless Sensor Networks
In wireless sensor networks, join queries execution introduces a high energy consumption. While energy is an important factor for sensors survival, several techniques were developed to reduce it. Sensors energy is affected by the number of…
Combining Image Processing Techniques and Mobile Sensor Information for Marker-less Augmented Reality Based Reconstruction
Marker-less Augmented Reality(AR) based recon- struction using mobile devices, is a near impossible task. When considering vision based tracking approaches, it is due to the lack of processing power in mobile devices and when considering mobile…
Pulsar Star Detection: A Comparative Analysis of Classification Algorithms using SMOTE
Pulsar is a highly magnetized rotating compact star whose magnetic poles emit beams of radiation. The application of pulsar stars has a great application in the field of astronomical study. Applications like the existence of gravitational radiation…
Classification of Facial Expression Using Principal Component Analysis (PCA) Method and Support Vector Machine (SVM)
Classification is a process to assert an object into one of defined categories. This study examines the classification of recognition of student’s facial expression during digital learning –indifferent and serious expression. The dataset used was…
A Framework for Verification in Contactless Secure Physical Access Control and Authentication Systems
Biometrics is one of the very popular techniques in user identification for accessing institutions and logging into attendance systems. Currently, some of the existing biometric techniques such as the use of fingerprints are unpopular due to COVID-19…
A Review of Smishing Attaks Mitigation Strategies
Mobile Smishing crime has continued to escalate globally due to technology enhancements and people's growing dependence on smartphones and other technologies. SMS facilitates the distribution of crucial information that is principally important for…
Review of Semantic Importance and Role of using Ontologies in Web Information Retrieval Techniques
The Web contains an enormous amount of information, which is managed to accumulate, researched, and regularly used by many users. The nature of the Web is multilingual and growing very fast with its diverse nature of data including unstructured or…
