#OCR TOOL LINUX SOFTWARE#
Therefore, OCR software tends to be imperfect, but it's often good enough to be worth using. This is an extremely challenging task for a computer program, though the software must overcome many obstacles, including streaks and blotches in the input file the varying sizes and appearance of characters in different fonts and the presence of nontextual information, such as embedded graphics. Essentially, the OCR package "reads" the characters out of the input file. Open the applications menu, search for gImageReader, and launch the app. These programs accept a graphics file as input and generate a text file that corresponds to the characters in the input file. Follow the instructions below to extract text from images or PDFs on Linux. To accomplish this goal, optical character recognition (OCR) programs exist. Sometimes, though, the purpose of scanning a document is to convert it to text in order to edit it in a word processor, load data into a spreadsheet, or otherwise manipulate it in a nongraphical way. Scanners are fundamentally graphics devices-their product is a bitmap graphics stream, which is easily displayed in an X window or saved in a graphics file.
