Automatic target image detection for morphing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In this thesis,we propose a novel approach for automatic target image detection for morphing based on 3D textons and contrast. Given the source image consisting of human frontal face and training images having human and ...
Object-background segmentation from video
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Fast and accurate algorithms for background-foreground separation are an essential part of
<p/>any video surveillance system. GMM (Gaussian Mixture Models) based object segmentation
<p/>methods give accurate results for ...
Fractal based approach for image segmentation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
In this thesis, we have proposed an algorithm for image segmentation, using the fractal codes. The basic idea behind this algorithm is to use fractal codes for the image segmentation. This method uses compressed codes ...
New learning based super resolution using contourlet transform
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
new learning based super-resolution reconstruction using contourlet transforms is proposed. contourlet transform provides high degree of directionality. It captures geometrical smoothness along multiple directions and ...
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 ...
FPGA implementation of image compression algorithm using wavelet transform
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This work presents FPGA implementation of image compression algorithm by using wavelet transform. Here the emphasis has been made on algorithmic encoding, the first step of image compression problem. The transform that has ...
Moment based image segmentation
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Usually, digital image of scene is not same as actual; it may degrade because of environment, camera focus, lightening conditions, etc. Segmentation is the key step before performing other operations like description, ...
Human action recognition in video
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Action recognition is a central problem in computer vision which is also known as action recognition or object detection. Action is any meaningful movement of the human and it is used to convey information or to interact ...
Active contours in action
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
There was considerable success in converting images into something like line drawings without resorting to any but the most general prior knowledge about smoothness and continuity. That led to the problem of “grouping” ...
Disparity estimation by stereo using particle swarm optimization and graph cuts
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Stereo vision is based on the process of obtaining the disparity from a left and a right view of a scene. By obtaining the disparity, we find the distance (depth) of each object point from the camera so that we can construct ...
