  • A design of HTM spatial pooler for face recognition using memristor-CMOS hybrid circuits 
    Ibrayev, Timur; James, Alex Pappachen; Merkel, Cory; Kudithipudi, Dhireesha (Institute of Electrical and Electronics Engineers Inc., 2016-07-29)
    Hierarchical Temporal Memory (HTM) is a machine learning algorithm that is inspired from the working principles of the neocortex, capable of learning, inference, and prediction for bit-encoded inputs. Spatial pooler is an ...
  • Detection and Analysis of Emotion from Speech Signals 
    Davletcharova, Assel; Sugathan, Sherin; Abraham, Bibia; James, Alex Pappachen (Procedia Computer Science, 2015-01-01)
    Abstract Recognizing emotion from speech has become one the active research themes in speech processing and in applications based on human-computer interaction. This paper conducts an experimental study on recognizing ...
  • Discriminative histogram taxonomy features for snake species identification 
    Mathews, Bincy; Sugathan, Sherin; Raveendran, Dileep Kumar; James, Alex Pappachen (Human-Centric Computing and Information Sciences, 2014)
    Background: Incorrect snake identification from the observable visual traits is a major reason for death resulting from snake bites in tropics. So far no automatic classification method has been proposed to distinguish ...
  • Edge-Aware Spatial Denoising Filtering Based on a Psychological Model of Stimulus Similarity 
    Mathew, Joshin; Zollanvari, Amin; James, Alex Pappachen (IEEE, 2017)
    Noise reduction is a fundamental operation in image quality enhancement. In recent years, a large body of techniques at the crossroads of statistics and functional analysis have been developed to minimize the blurring ...
  • Facial emotion recognising memristive threshold logic system 
    Mathew, Dayana; Sasi Kumar, Dinesh; James, Alex Pappachen (Institute of Electrical and Electronics Engineers Inc., 2016-06-09)
    The edge features in facial images change with changes in images, and are useful for automatically recognising the facial expressions. We present an edge feature extraction method using neuronal threshold logic models to ...
  • Heart rate monitoring using human speech spectral features 
    James, Alex Pappachen (Human-Centric Computing and Information Sciences, 2015-11-11)
    This paper attempts to establish a correlation between the human speech, emotions and human heart rate. The study highlights a possible contactless human heart rate measurement technique useful for monitoring of patient ...
  • Medical image fusion: A survey of the state of the art 
    James, Alex Pappachen; Dasarathy, Belur V. (Information Fusion, 2014-09-01)
    Abstract Medical image fusion is the process of registering and combining multiple images from single or multiple imaging modalities to improve the imaging quality and reduce randomness and redundancy in order to increase ...
  • Memristive Operational Amplifiers 
    Ibrayev, Timur; Fedorova, Irina; Maan, Akshay Kumar; James, Alex Pappachen (Procedia Computer Science, 2014-01-01)
    Abstract The neuronal algorithms process the information coming from the natural environment in analog domain at sensory processing level and convert the signals to digital domain before performing cognitive processing. ...
  • Memristive Threshold Logic Face Recognition 
    Maan, Akshay Kumar; Kumar, Dinesh S.; James, Alex Pappachen (Procedia Computer Science, 2014-01-01)
    Abstract This paper presents a face recognition method implemented using reconfigurable network of memristive threshold logic cells that can be practically realised in a secondary plane to the pixel arrays. Among the most ...
