Blind Modalities for Human Activity Recognition
2023Human Activity Recognition (HAR) has attracted considerable interest due to its ability to facilitate automation in various application areas, including but not limited to smart homes, active assisted living, and security. At present, optical modalities such as RGB, depth, and thermal imaging are prevalent in the field due to the effectiveness of deep ...

Indoor Sign Recognition for the Blind
Proceedings of the Annual Conference of the South African Institute of Computer Scientists and Information Technologists, 2016Blind people face difficulties when navigating unfamiliar environments. The information displayed on indoor signs and notice boards is of no use to them. In order to assist them with this challenge, we propose a real time system that can recognise a selection of indoor navigational signs placed over clear backgrounds.

Blind recognition of punctured convolutional codes
International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004This paper presents an algorithm for blind recognition of punctured convolutional codes which is an important problem in adaptive modulation and coding. For a given finite sequence of convolutional code, the parity check matrix of the convolutional code is first computed by solving a linear system with adequate error tolerance.

The Voice-Recognition Accuracy of Blind Listeners
Perception, 1983A research programme has been carried out that concerns the accuracy with which listeners can identify a speaker heard once before. The present study examined the voice-recognition abilities of blind listeners, and it was found that they could more accurately select target voices from the test arrays than could sighted people.

Distributed compression and the blind zone recognition
2016 International Wireless Communications and Mobile Computing Conference (IWCMC), 2016Wireless sensor network (WSN) technology provides support infrastructure to solve blind zone coverage. Previous studies mainly focus on deployment and management of sensor nodes for enhancing signal coverage on a specific zone. But few of them are on coordinating several nodes to recognize blind zone.

Blind-Road Location and Recognition in Natural Scene
2009 WRI World Congress on Computer Science and Information Engineering, 2009In this paper, we describe the dual-threshold processing technology based on gray histogram and carry on binary processing to the blind-road gray image according to the real-time requirement of blind man navigation system and the features of blind-road.

Pictorial Recognition and Teaching the Blind To Draw
Insight, 1980The author wished to discover how the blind mentally envisage three-dimensional form and if any connection existed between their conceptions and those of sighted persons. One question was if conventional orthographic presentations conveyed anything to the blind, or would three-dimensional representations be more meaningful?

Blind recognition of retransmitted packets for HARQ system
2003 IEEE Wireless Communications and Networking, 2003. WCNC 2003., 2004A simple approach to blindly detect the status of incoming packets (new or retransmitted), in a type-II selective repeat HARQ scheme is presented. Performance results are given showing that the approach is not only able to recognize new from retransmitted packets but also to properly associate retransmitted ones to already stored ones in the receiver ...

Blind Recognition of Touched Keys on Mobile Devices
Proceedings of the 2014 ACM SIGSAC Conference on Computer and Communications Security, 2014In this paper, we introduce a novel computer vision based attack that automatically discloses inputs on a touch-enabled device while the attacker cannot see any text or popup in a video of the victim tapping on the touch screen. We carefully analyze the shadow formation around the fingertip, apply the optical flow, deformable part-based model (DPM), k ...
