Grouping contents on Korean road signs

Content Provider Springer Nature Link

Abstract In this paper, we propose a method for grouping the content of Korean road signs into the five categories of Korean, English, direction symbol, road symbol and distance digit. The first step necessary to automate the inspection of road signs is to determine whether their content is reproduced as clearly as in the original design. Previously, inspections were performed manually by humans. Instead, we deal with images that are acquired manually by digital cameras, using various features including color, relative length and size, reflecting the design rule for Korean road sign. We began by analyzing blobs that are obtained through connected component analysis after binarization. These are first grouped into two categories: direction symbol and size. Then, the road symbol is selected using color. Finally, the remaining blobs are grouped using the relative length between blobs. Experimental results using real images show the feasibility of the proposed algorithm.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
