Optical Character Recognition (OCR)

 (OCR) Device:


          In this case a scanner is equipped with character recognition software which converts the images of characters to equivalent ASCII codes. The scanner first creates the image of the document, and the software(OCR software) translates the array of grid points in to ASCII text, which the computer can interpret as letters, numbers or special characters. OCR software is designed to recognize texts, which are written in some standard type of fonts called as OCR fonts. Two such standard fonts are OCR-A (American standard) and OCR-B(European standard) fonts, which are given here.

          Any document written in these fonts can only be recognized and processed by OCR technique. The CD-ROMs containing these fonts are either to be purchased or down loaded to a computer for creating documents, readable by an OCR scanner.

Automations and robotics

Automations and robotics refer to the use of technology to automate and perform tasks that were previously done by humans. Automation involves the use of software, machines, and other systems to perform tasks without human intervention. Robotics, on the other hand, involves the design and development of machines that can perform tasks autonomously or with limited human intervention. Automations and robotics are widely used in industries such as manufacturing, healthcare, transportation, and agriculture. In manufacturing, robots are used to perform repetitive and dangerous tasks, such as welding and painting. In healthcare, robots are used to perform surgeries and assist patients with mobility issues. In transportation, automated systems are used to control traffic flow and ensure the safety of drivers and passengers. In agriculture, robots are used to plant and harvest crops, reducing the need for manual labor. Advancements in technology have led to the development of more sophisticate...
