Research Interests


  • Data Compression - Design of smart multimedia(Text/Image/Video) compression algorithms based on Pattern Mining

    My research focused largely on designing efficient compression algorithms based on Knowledge Engineering perspective as suggested by Naren Ramakrishnan et. al. Initially, my concentration was predominantly on text and image compression using sub optimal patterns of our interest. We have used standard benchmark corpora for all types of data. Starting our journey with the design of modified efficient Huffman Encoding, we went on to design hybrid text compression strategies including Lempel-Ziv methods and other convenient compression mechanisms. We have also worked on the mathematical modeling of our compression techniques along with the correctness of the algorithms. For the past few years, I focus more on video compression where interesting mined patterns are used to efficiently compress videos.
  • Data Mining - Mining Frequent/Closed/Maximal/Rare patterns and clusters from large texts and images

    Some of my research interests are also across mining various types of interesting patterns from large datasets ranging from text, images and video. Along with this, I also focus on mining clusters from dense datasets using different types of clustering strategies.
  • Human-Computer Interaction - Design of Novel CAPTCHA’s for secure authentication

    Some of my research interests are also across mining various types of interesting patterns from large datasets ranging from text, images and video. Along with this, I also focus on mining clusters from dense datasets using different types of clustering strategies.
