Guide Me: Recognition and Servoing on Mobiles
Hafez, A. H. Abdul; Harit, Gaurav (SPRINGER HEIDELBERG, 2018-12)In this paper, we design and implement a human-machine interaction application, which enables a visually challenged person to locate and manipulate personal objects in her/his neighborhood. In this setting, we need to ... -
Learning multiple experiences useful visual features for active maps localization in crowded environments
Hafez, A. H. Abdul; Arora, Manpreet; Krishna, K. Madhava; Jawahar, C. V. (TAYLOR & FRANCIS LTD, 2016-01-02)Crowded urban environments are composed of different types of dynamic and static elements. Learning and classification of features is a major task in solving the localization problem in such environments. This work presents ... -
Multiple histogram-based face recognition with high speed FPGA implementation
Hafez, A. H. Abdul; Bonny, Talal; Rabie, Tamer (SPRINGER, 2018-09)Face recognition is an algorithm that is capable of identifying or verifying a query face from multiple faces in the enrollment database. It poses a challenging problem in the field of image analysis and computer vision, ... -
Particle-filter-based pose Estimation from Controlled Motion with Application to Visual Servoing
Hafez, A. H. Abdul; Cervera, Enric (SAGE PUBLICATIONS INC, 2014-10-31)In this paper, we present a Bayesian algorithm based on particle filters to estimate the camera pose for vision-based control. The state model is represented as a relative camera pose between the current and initial camera ... -
Partitioned environments for visual localization
Hafez, A. H. Abdul (Institute of Electrical and Electronics Engineers Inc., 2018-07-05)In this paper, we present a novel sequential visual localization algorithm in partitioned route. The algorithm utilizes Monte-Carlo for accurate visual localization. Partitioning the route into several regions produces ... -
Reactionless visual servoing of a multi-arm space robot combined with other manipulation tasks
Hafez, A. H. Abdul; Mithun, P.; Anurag, V. V.; Shah, Suril V.; Krishna, K. Madhava (ELSEVIER SCIENCE BV, 2017-05)This paper presents a novel and generic reactionless visual servo controller for a satellite-based multi-arm space robot.
