It is the popularly known and used technology to enter information from the printed documents. In other words, it digitalizes words so that you can easily use and view them in the machines. Read through to understand more about this technology.

In recent days, we can now use advanced OCR technology that produces a high accuracy recognition of different fonts with the help of the digital images. For other systems, they can easily reproduce the original page or the closest approximate to its original page which includes non-textual components such as columns. This capability helps us in making documents reading in class easier and faster.

Pre-processing technique

The OCR mostly uses the pre-processor style to guarantee successful recognition. The de-skew style helps the digital camera to tilt it in such a way that it results in successful recognition. The despeckle style successfully removes the negative and positive spots to smoothen the edges. For successful recognition, it also has a line and word detection, script recognition, character segmentation, and layout analysis. All these virtues help the Optical Character Recognition to settle for perfect images.

Character Recognition

This technique involves character recognition algorithms which help the item to produce an original page. The basic algorithm is pattern recognition or image correlation. It genuinely depends on the input glyph which is perfectly isolated from the other part of the image. It is the perfect style for typewritten text which is common in classroom documents. With this style, you can easily get an original page. The second style is using different software for character recognition.
