5 Best OCR Technology Tools & Android Apps to Extract Text from Images

Back in old times, people tend to do their work manually be it making the document or extracting text from an image.

Performing tasks with hands were not only time-consuming but also required mental and physical effort.

With changing time people are adapting to new things that save their time and energy, such as technical online tools.

Over time, technology has evolved significantly, and software and gadgets have become more efficient in providing good results to users.

There are numerous other tools available online to assist you in completing your work in a matter of seconds with accuracy.

This straightforward method will not work with images; you cannot simply highlight text and copy it from an image. When you have a snapshot of some text, you may need to extract the text from the photograph. Text can be extracted from photos using optical character recognition (OCR) software.

What Does Image to Text Mean?

It is a method for converting the text on any of your images into a text file. This is accomplished using image to text converters that employ Optical Character Recognition (OCR) technology.
OCR scans and converts an image’s transcript into a text file or document. The text of an image goes through many stages. Identification, digital scanning, and character coding are the steps involved. The data entry method has been greatly improved by the use of OCR.

What is the Process of OCR?

• Recognize pattern:

Using this method, the computer attempts to recognize the entire character and contrasts it to the program’s character matrix. This method is also known as pattern matching and matrix matching.

• Extraction of characteristics:

This is a much more precise method of detecting characters. Lines, line directions, closed loops, and junctions are features that are made by breaking down the characters.

• Text recognition improved using pre-processing:

To successfully recognize text, the program must first pre-process the image using techniques including:

• De-skew:

Tilting the image at an angle so that the text lines are either horizontal or vertical.

• De-speckle:

This is the procedure for removing blemishes and softening out the characters’ edges.

• Character segregation:

Characters who may have merged into one another are separated.

• Layout analysis:

All text positions, columns, and paragraphs are labeled.

• Line deletion:

Erasing overlapping lines or boxes with line deletion.

The Importance of OCR:

OCR technology helps you achieve increased output and productivity by saving time and energy that otherwise would have been spent on keeping records and data acquisition. Employees can quickly save data to their computer from any text document or an image, it saves their time and energy. You don’t have to spend money on data retrieval personnel because you have this awesome technology.
