What is ocr software?

1. Optical Character Recognition, or OCR, is a technology that enables you to convert Afferent types of documents, such as scanned paper documents, PDF files or images captured by a digital camera into editable and searchable data. In order to extract and repurpose data from scanned documents you need OCR software that would single

out letters on the image, put them first into words and then into sentences, thus enabling you to access and edit the content of the оn211 ml document.

2. The exact mechanisms that allow* humans to recognize objects are yet to be understood, but the three basic principles are already well known by scientists - integrity, purposefulness and adaptability (IPA). These principles constitute the core of ABYY FineReader OCR allowing it to replicate natural or human-like recognition.

3. Let's take a look on how* OCR software recognizes the text. First, the program analyzes the structure of the document image. It divides the page into elements such as blocks of texts, tables, images, etc. The lines are divided into words and then into characters. Once the characters have been singled out , the program compares them with a set of pattern images. It advances numerous hypotheses about what this character is. Basing on these hypotheses the program analyzes different variants of breaking of lines into words and words into characters. After processing huge number of such probabilistic hypotheses the program finally takes the decision, presenting you the recognized text.

4. Images captured by a digital camera differ from scanned documents. They often have defects such as distortion at the edges and dimmed light, making it difficult for most OCR applications to correctly recognize the text. Some OCR software supports adaptive recognition technology specifically designed for processing camera images. Such software offers a range of features to improve the quality of such images, providing you with the ability* to fully use the capabilities of your digital devices.

Ancestor of modern computers turns 60

1. The Small-Scale Experimental Machine, known as SSEM, or the "Baby", was designed and built at the University of Manchester, and made its first successful run of a program at И am, 21 June 194$. It was the first machine that had all the components now classically regarded as characteristic of the basic computer. "Baby" was the first "stored program computer", meaning it ran programs by loading them into a temporary memory store, or random-access memory (RAM), just as computers do today.

2. "That approach, and the fact the Baby was fully electronic, made it much easier to reprogram than previous computers," says Geoff Tootill, who helped design, build and test Baby. "Reprogramming earlier computers typically required physical changes to be made to a computer. We didn't set out to change the future of computing, only to demonstrate that the new storage system worked," Tootill adds.

3. Baby's RAM was based on cathode ray tubes (CRT) similar to those used in radar screens. A single tube could store 256 bytes of digital information. However, Baby only had a total of 12S bytes of functional memory. The first program Baby ran successfully could find the highest factor of any given number. Initially only tested on small numbers, the machine was soon tackling more difficult calculations. Running the program on the number 21S took about 2.1 million steps and 52 minutes. Reading the results required the decoding of digital output shown on another CRT tube.

4. From this "Baby" a full-sized machine was designed and built, the

Manchester Mark 1, which by April 1949 was generally available for computation in scientific research in the University. With the integration of a high speed magnetic (hum by the Autumn (the ancestor of today's disc) this was the first machine with a fast electronic and magnetic two-level store. It in turn was the basis of the first commercially available computer, the Ferranti Mark 1, the first machine off the production line being delivered in February 1951.
