Image ranking based on clustering
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
In a typical content-based image retrieval (CBIR) system, query results are a set of images sorted
by feature similarities with respect to the query. However, images with high feature similarities to the query may be very ...
Locality preserving projection: a study and applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Locality Preserving Projection (LPP) is a recently proposed approach for dimensionality
reduction that preserves the neighbourhood information and obtains a subspace that best
detects the essential data manifold structure. ...
Multiresolution fusion using compressive sensing and graph cuts
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Multiresolution fusion refers to the enhancement of low spatial resolution (LR) of Multispectral
(MS) images to that of Panchromatic (Pan ) image without compro- mising on the spectral
details. Many of the present day ...
Object segmentation in still camera videos
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The goal of object segmentation is to simplify and change the representation of an image into more meaningful so that it can easily analyse. Segmentation is the process of partitioning the digital image into multiple ...
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. ...
Super-resolution of hyperspectral images
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Hyperspectral (HS) images are used for space areal application, target detection and remote sensing application. HS images are very rich in spectral resolution but at a cost of spatial resolution. HS images generated by ...
Texton based auto region detection for image inpainting
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Historical monuments are considered as one of the key aspects for modern communities.
Unfortunately, because of variety of factors these monuments are sometimes damaged or
destroyed. Image inpainting is the process of ...
Transmultiplexer design using different filters
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Transmultiplexer is one of the applications of Filter banks, which is used to transmit many signals simultaneously through a single channel and so that to separate at receiving end. Design of transmultiplexer using prototype ...
Oblique projection operator
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
This thesis presents the understanding usefulness of Oblique Projector in signal processing like signal recovery, signal representation and reconstruction. This thesis also presents the different recursive oblique projector ...
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 ...
