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” ... -
Automatic car license plate recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)In most traffic applications, someone gathers information manually at the scene or watching the video of a scene. With automatic car license plate recognition using image processing techniques, new ways of capturing traffic ... -
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 ... -
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 ... -
Content-based image retrieval system for multi-object images using a combination of features
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)Content-based image retrieval (CBIR) is a research area dedicated to address the retrieval of images based on automatically derived features from the content of the images in database. Traditional CBIR systems generally ... -
Copy-Move Tampering: Some New Approaches of the Detection and Localization in a Digital Image
(Dhirubhai Ambani Institute of Information and Communication Technology, 2022)Images speak. They tell us stories. Digital images carry plethora of information. The availability of cost-effective digital camera-enabled devices has made capturing images a child’s play. Statistics witnesses that the ... -
Detection and localization of tampering in a digital medical image using discrete wavelet transform
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)Use of digital images has increased tremendously in medical science as a diagnosis tool. It made investigation easier and quick. But at the same time it raises the question of authenticity of the image under scrutiny. ... -
Differential geometry and image processing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)There are various ways of observing and interpreting images. At higher levels of abstraction, one looks at an image as collections of objects, while at the other end it is just a collection of curves and surfaces. We study ... -
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 ... -
Estimating depth from monocular video under varying illumination
(Dhirubhai Ambani Institute of Information and Communication Technology, 2014)Ability to perceive depth and reconstruct 3D surface of an image is a basic function of many areas of computer vision. Since 2D image is the projection of 3D scene in two dimension, the information about depth is lost. ... -
Fingerprint image preprocessing for robust recognition
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)Fingerprint is the oldest and most widely used form of biometric identification. Since they are mainly used in forensic science, accuracy in the fingerprint identification is highly important. This accuracy is dependent ... -
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 ... -
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 ... -
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 ... -
Image Processing Using Digital Programming on FPGA
(Dhirubhai Ambani Institute of Information and Communication Technology, 2023)Image processing is a way to transform an image into digital form and after thatperform some operations on it that helps to improve images for human interpretationand extract useful information from it. It is essential for ... -
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 ... -
Image segmentation fusion by edge detection techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2018)Image Segmentation is one of the basic building blocks in image processing.It is a pre-processing task to make an image processable for further operations such as noise removal,decomposition,morphological operations etc.It ... -
