Conditional models for 3D human pose estimation:
No full textHuman 3d pose estimation from monocular sequence is a challenging problem, owing to highly articulated structure of human body, varied anthropometry, self occlusion, depth ambiguities and large variability in the appearance and background in which humans may appear. Conventional vision based approaches to human 3d pose estimation mostly employed "top-down methods", which used a complete 3d human model, in a hypothesized pose, to explain the configuration of the humans in the observed 2d image. In this thesis, we work with "bottom-up methods" for human pose estimation, that use low level image features to directly predict 3d pose. The research draws on recent innovations in statistical learning, observation-driven modeling, stable image encodings, semi-supervised learning and learning perceptual representations. We address the problems of (a) modeling pose ambiguities due to 3d-to-2d projection and self occlusion, (b) lack of sufficient labeled data for training discriminative models and (c) high dimensionality of human 3d pose state space. In order to resolve 3d pose ambiguities, we use multi-valued functions to predict multiple plausible 3d poses for an image observation. We incorporate unlabeled data in a semi-supervised learning framework to constrain and improve the training of discriminative models. We also propose generic probabilistic Spectral Latent Variable Models to efficiently learn low dimensional representations of high dimensional observation data and apply it to the problem of human 3d pose inference.Ph.D.Includes bibliographical references (p. 182-193)by Atul Kanauji

Negi “A new secure route discovery protocol for MANETs to prevent hidden channel attacks
No full textAbstract In this paper, we propose a new secure route discovery protocol for MANETs that overcomes the vulnerabilities of Ariadne and EndairA, due to hidden channel attacks. It uses 'authentic neighborhood' for route discovery process which potentially protects hidden channels of routing control packets, besides ensuring authenticity and integrity of routing control messages at hop-by-hop level. This authentic neighborhood is augmented by a process of traceability which uses promiscuous mode of a node to detect, diagnose and isolate the adversarial nodes, that disrupt the route discovery process. We observe, from the comparative analysis of the proposed protocol with Ariadne and EndiarA, that the proposed protocol has a balance between security and computational overhead. Security analysis and formal verification, through extended BAN logic and AVISPA toolkit, shows that the proposed protocol is safe against the vulnerabilities identified in Ariadne and EndairA, due to unprotected hidden channels
Business and Politics in India
No full textOverview Description Table of Contents Author InformationCoverBusiness and Politics in IndiaEdited by Christophe Jaffrelot, Edited by Atul Kohli, and Edited by Kanta MuraliModern South AsiaDescriptionOver the last few decades, politics in India has moved steadily in a pro-business direction. This shift has important implications for both government and citizens. In Business and Politics in India, leading scholars of Indian politics have gathered to offer an analytical synthesis of this vast topic. Collectively, they cover the many strategies that businesses have used to exert their newfound power in recent times and organize the book around a few central concerns. They first analyze the nature of business power and how it shapes political change in India. Second, they look at the consequences of business' growing power on some important issue areas-labor, land, urban governance, and the media. Finally, they take account of regional variation and analyze state-business relations. This definitive account offers significant insights into how and why corporations have increased their power in contemporary Indian politics

A Comprehensive Method for Assessing the Blepharospasm Cases Severity
No full textBlepharospasm is characterized by bilateral, synchronous, and symmetric involuntary orbicularis oculi muscle spasms leading to partial/total eyelid closure. We proposed a comprehensive method for assessing the severity of blepharospasm cases, based on expert observation of fixed-length video recordings and natural feature detection algorithms. The developed software detects involuntary spasms and blinks in order to evaluate BSP severity. In this work we have considered a new BSP severity scale to realize an objective evaluation of BSP severity
Sensing multi-agent system for anomaly detection on crop fields exploiting the phenological and historical context
No full textIoT technology spread led to the development of smart solutions for Precision Agriculture, employing multiple smart sensors to acquire and process data to support vegetation monitoring and crucial tasks such as seeding, irrigation, etc. to improve crop quality and production. However, the gathering of data from multiple devices requires a data integration stage that strictly depends on the context and features of the environment, including the type of environment, species, and phenology of the area considered. To this purpose, this paper introduces a multi-agent model that allows a swarm of IoT devices to perform environmental monitoring and anomaly detection on Regions of Interest (ROIs) accomplishing several tasks, including harmonization of spectral images taken from different sources, phenology data extraction about ROIs to build contextual knowledge over the ROIs and anomaly detection through vegetation index classification. A case study in a simulated real-time environment demonstrates the potential of the model to promptly alert humans about ROIs affected by critical vegetation, burned areas, and ROIs that can be at risk after critical events occurred in their surroundings
