Automatic Object Detection Algorithm-Based Braille Image …
2022年2月18日 · To solve this problem, this study proposes a living assistance system, which integrates object recognition, object extraction, outline generation, and braille conversion algorithms, that is applicable both indoors and outdoors. The smart glasses guide objects in real photos, and the user can detect the shape of the object through a braille pad.
Anchor-Free Braille Character Detection Based on Edge Feature in ...
2022年8月8日 · Braille character detection helps communication between normal and visually impaired people. The existing Braille detection methods are all aimed at scanning Braille document images while ignoring natural scene Braille images and CNN shining in the field of pattern recognition is rarely used for Braille detection.
Characterization of English Braille Patterns Using Automated …
2022年2月25日 · An image-based Braille character recognition for English and Sinhala was performed using SVM with a Histogram of Oriented Gradient (HOG) feature extraction method. Characters were extracted after applying preprocessing steps and segmentation techniques.
Anchor-Free Braille Character Detection Based on Edge Feature in ...
2022年8月8日 · Firstly, a natural scene Braille image data set named NSBD was constructed. Then, an anchor-free Braille character detection based on the edge feature was proposed by analyzing that Braille characters in natural scene images that are relatively small in size, and a Braille character is composed of Braille dots that werelocated at the edge ...
A 2D Refreshable Braille Display Based on a Stiffness Variable …
2022年3月22日 · In this work, we present the design and operating mechanism of Braille PolyPad, a prototype 2D refreshable braille display featuring 4×10 braille cells, enabling the transformation of images to 2D braille information. The Braille Polypad is based on a miniature pump enabled pneumatic actuation of Braille pins.
Automatic Object Detection Algorithm-Based Braille Image
2022年2月18日 · The smart glasses guide objects in real photos, and the user can detect the shape of the object through a braille pad. Moreover, we built a database containing 100 objects on the basis of a survey to select objects frequently used by visually impaired people in real life to construct the system.
Digital Braille Watch 3 Abstract The Braille language has provided the visually impaired with a way to read and write for many years, yet no device exists that allows the visually impaired to read the time in Braille. In order to tell time, the
Image-Based Recognition of Braille Using Neural Networks on …
2020年9月4日 · In this paper, we present the development of a mobile Optical Braille Recognition (OBR) system using state-of-the-art deep learning techniques. There are many approaches dealing with Optical Braille Recognition. An overview of seven different optical Braille recognition algorithms are given by Isayed and Tahboub (2015) [7].
Digital Braille Watch 4 Braille Basics The Braille language is the universally accepted form of written communication for the visually impaired. It utilizes a system of dots arrayed in a three row by two column grid. Raised dots are then located in any of the
Towards Tangible Vision for the Visually Impaired through 2D …
2019年12月3日 · 4.5. Braille Image Translation Based on 2D Multiarray Braille Display. This section presents a braille figure conversion system, which was developed by InE Lab and Professor Cho at Gachon University, who conducted this joint research and has presented novel methodologies for automatic text and graphics translation to braille.
