In the following section we'll go into the basics of text detection, exploring its definition and functionality.
What is a Text Detector?
A text detector is a program or tool that can identify and extract text from images or videos.
Its purpose is to find areas in an image or video frame where text is located and then capture that text. Various kinds of text detectors exist, utilising techniques such as machine learning, computer vision and deep learning.
Text analysis tools have a variety of uses, such as Optical Character Recognition (OCR) retrieving images based on text and finding videos based on text. OCR is the conversion of text images into formats, like Word or PDF. Searching for images or videos based on the text they contain is also commonly done.
But first…
How Does a Text Detector Work?
Text detectors function by examining the attributes of an image or video frame to pinpoint areas that probably have text.
They employ methods, like detecting edges, analyzing colours and studying textures for this task. After locating the text regions the text detector proceeds to extract the text from those areas utilising OCR or similar methods.
One popular method for detecting text involves the use of a sliding window technique.
This technique entails moving a window across the image or video frame and examining the contents of each window to determine if it includes text. Another method is to utilise a network (CNN) to pinpoint text areas within an image or video frame. CNNs are a form of deep learning algorithm of learning patterns in images and videos.
In general text detection proves to be an asset, for automating a variety of tasks related to identifying text in forms. Employing a text detector enables companies and institutions to enhance efficiency, save time and optimise resource utilisation.
