| Abstract | Urdu word spotting is among the most challenging tasks in image processing and word spotting of hand written Urdu text is even more so. When it comes to handwritten Urdu documents, variation among the same words of various writers is significant. The orientation and style of the handwriting makes it really challenging for a word spotting system to correctly recognize the instances of the keyword. In this research, we tend to overcome this hurdle. We propose a system that takes a database of hand written Urdu text and generates random, yet, similar images to improve the classifier's ability to recognize variations caused by difference in handwriting. For image generation, we used geometric transformations and variants of Generative Adversarial Network (GAN). For the word spotting process, Histogram of Oriented Gradients (HOG) features are extracted from ligature images and then used to train a Long Short-Term Memory (LSTM) network for the classification task. This is the first study that focuses on improving word spotting by generating arbitrary samples using GANs and its variants. The system achieved a promising recognition rate of 98.96% due to the sample generation using Cycle-GANs. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
