dc.description.abstractScene Text Recognition (STR) is synonymous with text recognition in the wild scene, and it is a difficult task since it necessitates getting rid of text strokes and their fuzzy borders, such as embossing, shading, and flare, from an image and then sharpen the latent text. STR has become widely researched because of application areas that cover most everyday activities for both humans and their technological advancement (such as self-driven vehicles and Artificial intelligence gadgets). Existing approaches must fully address the complex problems that arise in the wild regarding text recognition and detection, such as blurred images, which is an aspect of the task for this study. Again, research has recommended using Dimensionality Reduction (DR) and Genetic Algorithm (GA) to instantiate text recognition. Hence, it has given rise to using GA for DR as recommended. Here, we develop two major DR models: the DR model using ICA for pre-processing of the dataset and the DR model using an Independent Component Analysis (ICA) – Enhanced Genetic Algorithm using the Bird Approach (BA-GA), making the ICA-BA-GA model for text deblurring in the wild, coupled with SVM, K-NN, and Ensemble for evaluating the models. The study uses Large-Scale Street View 2019 ICDAR Text (LSVT19), which has 20,000 test photos, 30,000 annotated training images, and 400,000 unlabeled or partially labeled training images. Evaluation parameters such as accuracy, precision, and f1-scores were used for benchmarking. For accuracy compared to the state of the art, ICA-BA-GA gives an impressive 99%. For the improved model (ICA-BA-GA) using the classifiers - with the ensemble, we get the best result (99.30%): K-NN 98.65% and SVM 94.01%. Further research could investigate a hybrid using Neural Networks. A different dataset, preferably one curated by scholars with various categories of blurriness, can be used.
