    New learning based super resolution using contourlet transform
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Singh, Vineet P.; Joshi, Manjunath V.
    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 learns the edges present in an image normal to the contour. For learning purpose, training set of low resolution (LR) and high resolution (HR) images, all captured using the same camera, are used. Here two and three level contourlet decomposition for LR images (test image and training image dataset) and HR training images respectively. The comparison of contourlet coeffcients of LR test image from the LR training set using minimum absolute difference (MAD) criterion to obtain the best match contourlet coeffcient. The finer details of test image are learned from the high resolution contourlet coefficients of the training data set. The inverse contourlet transform gives super resolved image corresponding to the test image.

    Vehicle detection and tracking
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Rao, K. Ramprasad; Joshi, Manjunath V.
    Real time trafficc monitoring is one of the most challenging problems in machine vision. This is one of the most sorted out research topic because of the wide spec-trum of promising applications in many areas such as smart surveillance, military applications, etc. We present a method of extracting moving targets from a real-time video stream. This approach detects and classifies vehicles in image sequences of trafficc scenes recorded by a stationary camera. Our method aims at segregating cars from non-cars and to track them through the video sequence. A classication criteria based on the features is applied to these targets to classify them into categories: cars and non-cars. Each vehicle can be described by its features. The template region is estimated by means of minimum distance approach with respect to centroid of the obtained blob of the target. Extraction of features from each frame ensures eefficiency of the tracking system.

    Particle swarm optimization based synthesis of analog circuits using neural network performance macromodels
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Saxena, Neha; Mandal, Sushanta Kumar
    This thesis presents an efficient an fast synthesis procedure for an analog circuit. The proposed synthesis procedure used artificial neural network (ANN) models in combination with particle swarm optimizer. ANN has been used to develop macro-models for SPICE simulated data of analog circuit which takes transistor sizes as input and produced circuit specification as output in negligible time. The particle swarm optimizer explore the specfied design space and generates transistor sizes as potential solutions. Several synthesis results are presented which show good accuracy with respect to SPICE simulations. Since the proposed procedure does not require an SPICE simulation in the synthesis loop, it substantially reduces the design time in circuit design optimization.

    Dharti ke lal: sons of soil
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Kholia, Puru; Desai, Binita; Mazumdar, Madhumita; Pandya, Vishvajit; Kumar, Arnav
    An integral part of physical culture, Pehelwani prevails in India since ancient times and having undergone several changes, it still exists in a slightly different form however it is not as popular as it used to be a few decades ago.Pehelwani influenced the general lifestyle of many individuals, and for centuries it has been appreciated by the masses as the most popular form of entertainment.Certainly it is something which supports the formation of a healthy body residing in a health conscious environment and it is for this reason Pehalwans are so passionate about the Akharas and their Gurus. Governed by various social and economic environment factors there had been many ups and downs in Pehelwani and the lifestyles of Pehelwans By presenting a precise overview which includes how Pehelwani is associated with Hindu mythology, preindependence,post independence and the current times,and therefore, deriving an exact description comprising of its essential ingredients, the project is intended to reveal the social aspects of Pehelwani in an interrogative manner and therefore bringing its current scenario in a realistic way. While covering different kinds of changes that took place in Pehelwani in a rationalistic manner that is to document the reasons behind those changes, the project shall convey, with striking eloquence a message about those aspects of pehelwani which are scarcely given any importance.

    What child art could say?
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Kaur, Abhineet V.; Pandya, Vishvajit
    “What child could say?” is project which intents to design a communication of public interest message for middle class urban Indians. It is to alert parents in the direction of importance of family peace and harmony. And to be sensitized to the impact of domestic conflict on there children in the family. It is a message in which a child drawn image is made to say to the adult’s world for not letting him grow in a place that is dark and unconstructive rather provides an environment which is bright and blissful for them to grow.

    Devo athithi bhava-athithi devo bhava: an event where God come in as guest and guest comes as God
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Sharma, Neha; Pandya, Vishvajit
    “Devo Athithi Bhava, Athithi Devo Bhava” is an exploration of a unique cultural phenomenon which leads to social, political and economical context of the place. It focuses on the festival “Dusshera in Kullu” where the Gods come as guests. The tourists i.e. guests who visit the place are also treated like God to the place. Project is basically to promote ‘Tourism in Kullu’ which is further exploration of not only the ‘unique way of celebrating this festival but also communicates the “Impact of culture tourism” on and by the people of Kullu in Himachal Pradesh. It invites the user to explore not only the culture and belief of the festival in the context of its celebration but also to assist the viewer to know about the local people and the place, where tourism potential provides the State, the tourist as well as the local people benefit, by organizing such culturally accepted festivals and events. Tourists are derived of opportunities to enjoy the rural, remote and the most scenic parts of the state due to lack of awareness. Thus, project explores them to find other places in the district those have equal cultural tourism potential. It generates critical awareness among the tourist who are visiting the place to get authentic information about the event. It also gives information to the viewer about the culture diversity in India and gives knowledge of the tradition of celebrating dusshera festival in various parts of the country in different ways with independent history related to it.

    Darshan on the highway: urbanisation and popular religion in contemporary Ahmedabad
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Anglay, Hemang; Mazumdar, Madhumita
    Darshan on the Highway is a multimedia news story which is incorporated in a news website. It brings out the quality and characteristics of New SG Highway. In the recent years a new lifestyle has emerged on account of growing economy around the city of Ahmedabad. Two major forms of structures which emerged are the 'Temples' as well as the 'Business' complexes. Mainly the religious structures and business structures are the two main segment which share a symbiotic relationship between them, and also constitutes to the Visual Display of the entire stretched area. It has changed the economics of this stretch of the city making it a hub of a range of malls, multiplexes and restaurants. The temple complexes along with shopping complexes make the SG Highway a unique site for the study of the nature of urbanization and popular religious practice in contemporary Gujarat. It brings out the recent change which has transformed into a cultural phenomenon - The co-existence of economic enterprise and spirituality. It deals with the demands of work, leisure and religiosity in the best possible ways. The SG highway has attracted both citizen and media attention in recent times because of its mushrooming temple complexes and replicas of popular shrines on pilgrim circuits. Keeping this exceptional feature as the driving force I have tried to create a multimedia presentation in a sequence which might open up the curtains one by one. A news feature on the SG Highway had already appeared in the Ahmedabad edition of the Times of India on the 24th of July 2003. At that point the temples complexes had just begun to take shape with the successful replication of the Vaishno Devi Temple. My news story brings the story down further to 2009 to show the more recent replication of the Tirupati Balaji temple. The news feed drives the user to explore the replicas of two major shrines one being from north and the other being from the south, as well as its implications in contemporary senario. Namely, the Vaishnavdevi temple and the Tirupati Balaji temple on SG Highway. Given the spatial limitations of the multimedia news format, I have chosen to depict some salient features of the SG Highway focusing in particular on the replica shrines and their significance for visitors and devotees in the city of Ahmedabad.

    Christianity and Kathakali: Dance - drama of Kerala
    (Dhirubhai Ambani Institute of Information and Communication Technology, 2009) Alex, Abin; Sarkar, Aditi Nath
    Kathakali and Christianity have long been associated with the state of Kerala. Both have had their own independent identity. Since Kathakali was not an art form that portrayed the Biblical stories and it was confined within the temple compound, in the early years an intermingling of them was a question out of context. Though Christians in Kerala are known to have co-existed with native culture of Kerala, the arrival of Portugese and strict rules imposed by the Christian orthodox authority saw the community taking less to the native culture. This resulted in the formulation of new art forms exclusively belonging to the Christians of Kerala like Margamkali and Chavitunadakkom. Moreover, the mythological stories that are part and parcel of Kathakali performance where considered to be chiefly belonging to Hindus. There were rites and rituals before, during and after the performance of Kathakali that led people from non-Hindu community to make unfriendly them from the art form. It was not until the 1960s that the ruling of the second Vatican council and the efforts of people to make Kathakali represent Kerala rather than a particular division, those stories from Bible made their way into the literatures of this dance form. This development is recent comparing with the time these two entities have been existing in Kerala. There is the need for familiarizing the masses about this as the growth of this segment of Kathakali is oblivious to a lot of people. I intend to meet this end through this project.
