Education

UNIVERSITY OF PENNSYLVANIA, Philadelphia, PA

  • Master of Science in Robotics, May 2011
    • Simultaneous Localization and Mapping with Kinect Sensor (SLAM) (MATLAB, C++, 2011) 
      Created map and localized robot simultaneously from the sensor data. (LIDAR, accelerometer and gyro) Unscented Kalman Filter for IMU orientation and Particle Filter for SLAM are used. 3D mapped with Kinect depth image over 2D map.
    • Automatic Logo Replacement (MATLAB, 2010)
      Replaced logo automatically using Shape Context, HoG, Thin Plate Spline, Homography and Adaptive RANSAC.
    • Jigsaw Puzzle Solver (MATLAB, 2010)
      Solved Jigsaw puzzle problems with an image of scattered pieces and an original image using Edge detection, Segmentation and SIFT. Found the relationships, proper locations and orientations of pieces and constructed a solved picture.
    • Developing age and gender prediction algorithms (MATLAB, 2009)
      Trained machine and made prediction of age and gender from blog postings (text) and faces (images). Applied and analyzed SVM, PCA, Kernel Logistic Regression, Gaussian Naive Bayes, AdaBoost with weighted Naive Bayes to the data. Used Cross Validation to check the estimated result. 2 members in one team. Got 1st place in the Machine Learning class.
    • Mobile robot slalom using vision recognition (MATLAB, 2009)
      Controlled a 3-wheels mobile robot to pass through the gates as fast as possible using vision detection with a web camera on top of the robot. Used HSV and RGB color to distinguish objects and Geometric approach to calculate distance and angle of the objects.
