  4. 4. Soumyadip Chandra In this project the intensity calibration of airborne laser scanner data is performed without using any known brightness targets. The data was calibrated with itself using a calibration formula developed by Finnish Geodetic Institute. The key concept of this calibration process is objects with same material should always show same intensity values. But due to distance from the scanner, scan angle and object geometry this does not happen often. The average flying height was about 1100 meter above ground level. Intensity values need to be corrected with respect to range, incidence angle, atmospheric transmittance and transmitted power (because difference in PRF will lead to different transmitter power values). After these corrections, the intensity values were directly relative to target reflectance. The algorithm has shown promising result. b) 3D modeling using LiDAR data c) Integration of GPS and IMU d) Terrestrial laser scanner (TLS) data processing SKILL SETS • Languages: Matlab, C, C++ • Softwares: Image processing: ERDAS Imagine (8.5 & 9).

Machine Processing of Remotely Sensed Data Developed Matlab code for Independent Component Analysis for Image classification ACADEMIC PROJECTS M.TECH THESIS (JULY’09-JULY’10) UNSUPERVISED AND SUPERVISED LEARNING WITH HYPER-SPECTRAL DATA ORGANIZATION: INDIAN INSTITUTE OF TECHNOLOGY KANPUR Project Detail: Hyper-Spectral data (HD) classification is a challenging job with respect to multispectral data set due to high dimensionality of data set. The data set are highly correlated. So some feature extraction process should be applied to reduce the dimensionality of the data set. The objectives of this thesis are to investigate the extension to which advanced classifier can reduce the problems of classification for hyperspectral data and Investigation of best feature reduction techniques for hyperspectral data classification, conventional as well as advanced classifier. After performing different experiments it was confirmed that HDresponses best with segmented principal component analysis (SPCA)(Feature extraction technique). After applying SPCA, Support vector machine with quadratic programming optimizer provides best classification result than any other feature extractors and classifiers with statistically large set of training pixels. But for statistically sufficient set of training pixels SVM’s performance is not statistically better than parametric classifier like Gaussian Maximum likelihood (GML). It is strongly recommended that for statistically sufficient set of training pixels GML should be applied for classification of HD. For both the case SPCA is the best feature extraction techniques among all others. Another problem of classification is time requirement. With large set of training sample HD requires large training time. But this process reduces classification time significantly. Still now this proposal is the best for HD classification Programming Tools: Matlab ACHIEVEMENTS • Secured 2nd highest CPI in Geoinformatics in M.Tech. Batch 2008.
