Binarizing degraded document image for text extraction
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)The recent era of digitization is expected to be digitized many old important documents which are degraded due to various reasons. Binarizing Degraded Document Image for Text Extraction is a conversation of document color ... -
Classification of 3D volume data using finite mixture models
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)The 3D imaging provides better view of objects from three directions as compared to 2D imaging where front face of object can be viewed only. It involves a complex relationship as compared to 2D imaging and hence computationally ... -
Depth from defocus
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)With the recent innovations in 3D technology accurate estimation of depth is very fascinating and challenging problem. In this thesis, a depth estimation algorithm, utilizing Singular Value Decomposition to compute orthogonal ... -
Learning based approach for image compression
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)Data compression is a process of storing same information with less data or space in computer memory. There are many image compression techniques that are available for storing images with less storage space. Minimizing ... -
Multiresolution fusion of satellite images and super-resolution of hyper-spectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)This thesis presents a model based approach for multi-resolution fusion of the satellite images. Given a high resolution panchromatic (Pan) image and a low spatial but high spectral resolution multi spectral (MS) image ... -
On designing DNA codes and their applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2019)Bio-computing uses the complexes of biomolecules such as DNA (Deoxyribonucleic acid), RNA (Ribonucleic acid) and proteins to perform the computational processes for encoding and processing the data. In 1994, L. Adleman ... -
Practical approach for depth estimation and image restoration using defocus cue
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)Reconstruction of depth from 2D images is an important research issue in computer vision. Depth from defocus (DFD) technique uses space varying blurring of an image as a cue in reconstructing the 3D structure of a scene. ... -
Techniques for denoising brain magnetic resonance images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)Advances in the computational science joined medical imaging domain to help humanity. It offers great support in clinical practices where automatic Computer Added Systems (CAD) help in identification and localization of ...
