PROJECTS

Human Communication and Machine Learning
  • Worked on recognizing and predicting human behavioral patterns and emotions using visual and vocal cues for my term project.
  • I am using Semaine database for my project. The database contains data pertaining to various shades of human emotions (visual and vocal).

Directed Research – Prof C. -C. Jay Kuo
  • Working on privacy in online social networks and the behavior of online users can be modeled using their context
  • Behavior models can be extracted using various signals obtained from the user's activity and the network dynamics

Directed Research – Prof Keith Jenkins
  • Worked on multiclass object recognition using biologically inspired features
  • Explored state of the art algorithms like HMAX, SIFT, SURF, pyramid kernel etc. Object recognition is the holy grail of computer vision and we need to work with models which are as close to the human visual system as possible.

Multimedia Data Compression
  • Developed and implemented a spatially scalable video coding technique using discrete wavelet transform in MATLAB for my term paper
  • Designed and implemented various algorithms for multimedia data compression in C/C++. The algorithms included Shannon-Fano coding, Huffman coding, Adaptive Huffman coding, Run length coding and its variants, QM coder, Lloyd-Max scalar and vector quantizer, Tree Structured Vector Quantization, JPEG rate control and compression quality factor, Post processing of JPEG images, Analysis and rate control in MPEG-1 and MPEG-2 video encoders

Digital Image Processing
  • Developed and implemented a Face Recognition system in MATLAB for my term paper
  • Designed and implemented various algorithms for image processing in C/C++/MATLAB. The algorithms included digital watermarking, image enhancement, edge detection, morphological processing, digital halftoning, geometric modification of images, texture analysis and optical character recognition


Mathematical Pattern Recognition
  • Developed and implemented a pattern classification system for my term project in MATLAB. The project included classifying forensic glass database and optical digit recognition (0-9) on NIST database (10,000 images).
  • The algorithms included various supervised and unsupervised learning techniques like Perceptron, Widrow-Hoff method, pseudoinverse method, support vector machines, K-nearest neighbors, transforming the data into another domain to obtain better results, dimensionality reduction techniques like Principal Component Analysis, Linear and quadratic Bayes classifier etc.

At NITK Surathkal, India (Undergraduate University)

Real-time Isolated Word Recognizer (speech recognition)
  • Developed an isolated word recognizer which could take in real time input and recognize the words
  • Parallel dynamic time warping technique was used to achieve faster real time recognition

Compressive Sensing for Audio and Images (image and audio compression) 
  • Compressive is a technique for acquiring and reconstructing a signal utilizing the prior knowledge that it is sparse or compressible by sampling the signals at less than Nyquist sampling rate
  • Developed algorithms for compressive sensing of images and audion using linear and non-linear optimization techniques

JPEG encoder with variable image compression rate
  • Developed a JPEG encoder in C using adaptive huffman coding and user controlled rate-distortion trade-off
