Texts have become an integral part of urban as well as rustic landscapes. Starting from directions, street names, milestones, public notices and traffic signboards to hoardings and advertisements—we can find text everywhere. Text detection in natural scenery, more popularly known as “Scene Text Detection”, has been an extensive field of study in the domain of Image Processing. Yet, owing to the varying alignment, quality, clarity, distance and other parameters of non-uniformity that are present in such types of text, researchers have not been able to completely saturate this aspect of Image Analysis. As more work is being done, we get a better understanding in this regard. But, it is still far from complete resolved. In this paper, the author has proposed a technique for scene text detection using time-frequency analysis.
