Blind recognition of punctured convolutional codes

International Symposium onInformation Theory, 2004. ISIT 2004. Proceedings., 2004
This paper presents an algorithm for blind recognition of punctured convolutional codes with application for instance in adaptive systems. Minimal basic encoding matrices of the original convolutional codes and their puncturing patterns are determined according to the accounted parity check matrices of the punctured convolutional codes.

VISUAL RECOGNITION For BLIND PEOPLE

International Journal on Science and Technology
The inability to perceive visual surroundings makes daily navigation and information access challenging for blind individuals. This paper presents a comprehensive system named Visual Recognition for Blind People, which integrates computer vision and artificial intelligence to provide real-time environmental understanding and assistance.

Smartphone based face recognition tool for the blind

2010 Annual International Conference of the IEEE Engineering in Medicine and Biology, 2010
The inability to identify people during group meetings is a disadvantage for blind people in many professional and educational situations. To explore the efficacy of face recognition using smartphones in these settings, we have prototyped and tested a face recognition tool for blind users.

Orientation-invariant object recognition: evidence from repetition blindness

Cognition, 2005
The question of whether object recognition is orientation-invariant or orientation-dependent was investigated using a repetition blindness (RB) paradigm. In RB, the second occurrence of a repeated stimulus is less likely to be reported, compared to the occurrence of a different stimulus, if it occurs within a short time of the first presentation.

Research on Watermark Tampering Blind Recognition Algorithm Based on Recognition Factor

2019 Chinese Control Conference (CCC), 2019
As an important protection method of digital copyright, whether digital watermarking technology can effectively identify tampering attacks and protect watermark information is an important research topic in the field of digital copyright. In this paper, a dual watermarking algorithm based on discrete cosine transform and discrete wavelet transform in ...

Print recognition apparatus for blind readers

Journal of the British Institution of Radio Engineers, 1962
The facilities offered both to designer and reader by the auditory and tactile types of reading machine are compared. Methods used for solving the problem of producing an electrical signal equivalent to each of a set of printed characters are discussed and some actual machines briefly described. The types of machine required by the blind and facilities

Blind recognition of punctured convolutional codes

Science in China Series F, 2005
This 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.

Sentence context, word recognition, and repetition blindness.

Journal of Experimental Psychology: Learning, Memory, and Cognition, 2002
When the sentence She ran her best time yet in the rice last week is displayed using rapid serial visual presentation, viewers sometimes misread rice as race (M. C. Potter, A. Moryadas, I. Abrams, & A. Noel, 1993). Seven experiments combined misreading and repetition blindness (RB) paradigms to determine whether misreading of a word because of biasing ...

Pictorial Recognition and Teaching the Blind To Draw

Insight, 1980
The 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?

Distributed compression and the blind zone recognition

2016 International Wireless Communications and Mobile Computing Conference (IWCMC), 2016
Wireless 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.
