    Verma, Sagar; Arora, Chetan (Advisor) (2017-07)
    With an increase in usage and availability of wearable devices like GoPro, Microsoft Hololens, Google Glass, etc, egocentric video analysis has become essential. An interesting application is action recognition in egocentric ...
  • Analysing long egocentric videos 
    Nagar, Pravin; Arora, Chetan (Advisor) (IIIT-Delhi, 2023-02)
    Egocentric videos are recorded in a hands-free, always-on, under enhanced privacy-sensitive scenario and are often collected from day to weeks. For efficient consumption, such videos require robust video analysis techniques ...
  • Brain MRI segmentation 
    Agarwal, Ayush; Sinha, Akshat; Arora, Chetan (Advisor); Gupta, Anubha (IIIT-Delhi, 2017-04-18)
    The automated segmentation of Brain MRI is an important initial step in the application of anomaly detection and pain localization due to neurological diseases. In this view, we aim to segment the sub structures (Caudate, ...
  • Camera pose estimation 
    Verma, Ishita; Saran, Nitika; Arora, Chetan (Advisor) (IIIT-Delhi, 2017-04-18)
    Pose estimation is a fundamental problem in computer vision and is prevalent in numerous applications such as object-detection, tracking etc. Generally, in pose estimation between two camera views, we have 6 degrees of ...
  • Capturing mannerisms in speech data 
    Nambiar, Pranav; Arora, Chetan (Advisor); Anand, Saket (Advisor) (IIITD-Delhi, 2018-04-30)
    Text-to-speech systems generally require large amounts of annotated speech data with the quality of both the annotations and speech being a huge factor. As a result, most of the research performed has been on highly curated ...
  • Deep learning based multitask learning for first-person videos 
    Gupta, Divam; Arora, Chetan (Advisor) (IIIT-Delhi, 2016-07-18)
    First person videos captured from wearable cameras are growing in popularity.Standard algo- rithms developed for third person videos often do not work for such egocentric videos because of drastic change in camera ...
  • Detecting cows and dogs on delhi streets 
    Saurav, Sakti; Arora, Chetan (Advisor) (IIIT-Delhi, 2016-11-17)
    Did you know that India is now the home to world's largest number of blind people? 41% of the blind population are from India. And one of the real security concerns of visually impaired persons is that whether they get ...
  • Efficient algorithms for MRF-MAP inference problem: using polytope based methods in conjunction with flow based methods 
    Wala, Rounaq Jhunjhunu; Arora, Chetan (Advisor) (IIIT-Delhi, 2017-04-18)
    Use of higher order clique potentials in MRF-MAP problems has been limited primarily because of the inefficiencies of the existing algorithmic schemes. A combinatorial algorithm called Generic Cuts Algorithm was proposed ...
  • Exploiting independent visual and textual data sources to improve multi-modal methods for description and querying of visual data 
    Pal, Ambar; Sharma, Gaurav (Advisor); Arora, Chetan (Advisor) (IIIT-Delhi, 2016-07-18)
    Recent methods on combining textual and visual information using supervised (textual, visual) data have shown encouraging performance. However they are mostly limited to paired (textual, visual) data. We are interested ...
  • Extending a scaling based flow algorithm for higher order MRF-MAP inference in vision 
    Prasoon; Arora, Chetan (Advisor) (2016-09-13)
    Several tasks in computer vision and Machine Learning are modeled as MRF-MAP inference problems. The problem can often be modeled as minimizing sum of submodular functions. Since, sum of submodular functions (SoS) is also ...
  • Mobility Assistant for the Visually Impaired 
    Verma, Arsh; Gupta, Anubha (Advisor); Arora, Chetan (Advisor); Balakrishnan, M. (Advisor) (IIIT- Delhi, 2021-05)
    Scene Text Recognition (STR) refers to the task of recognition of text in natural scenes. The success of OCR models is hard to achieve on natural scene images due to a variety of challenges, including - variation in ...
  • Modeling and implementation of real-time animal detection module for mobility assistant for visually impaired (MAVI) system 
    Verma, Richa; Arora, Chetan (Advisor) (2017)
    India is currently home to around 12 million blind people out of 39 million globally - one-third of the world's blind population resides in India. People with low vision or complete blindness find it hard to navigate ...
  • Modelling and implementation of real time texture detection module for mobility assistant for visually impaired system (MAVI) 
    Agarwal, Prerna; Arora, Chetan (Advisor) (2017-07)
    As the volume of video data is increasing day by day, real-time video processing is becoming an important application to build any real time device based on image processing. An interesting task that is crucial for the ...
  • Optimal inference algorithms for higher order MRF-MAP problems 
    Ishant; Arora, Chetan (Advisor) (IIIT-Delhi, 2020-08-13)
    Many computer vision problems can be formulated as finding the best labeling configuration. If labelings satisfy Markov property then finding best labeling configuration becomes MRF (Markov Random Field)- MAP (Maximum A ...
  • Question answering system based on sentence similarity 
    Kashif, Mohammed; Arora, Chetan (Advisor) (2017-06)
    Question-Answering systems are becoming increasingly popular, especially after the advent of Machine Learning. Such systems can be used in a wide variety of applications ranging from Open domain question answering or closed ...
