A dataset for the recognition of obstacles on blind sidewalk
Universal Access in the Information Society, 2021Recently, the technology of assisting the navigation of visually impaired persons with computer vision has been greatly developed. A number of scholars have conducted related research, including indoor and outdoor object detection for blind people. However, there are still problems with some existing methods or datasets.

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.
