Understanding Optical Character Recognition (OCR)

How to Extract Text from an Image Using OCR. Optical Character Recognition (OCR) refers to a technology that allows for the electronic extraction of text from an image. This text can be handwritten, typed, or printed, and can come from a scanned document or an image of the document itself. OCR technology is capable of extracting text from image files for further utilization, making it a valuable tool in various fields and applications.

How Copyleaks Utilizes OCR Technology for Plagiarism Detection

Copyleaks has introduced a feature that is capable of detecting similar text across various file types by employing OCR technology to extract text from images. This proves to be incredibly useful in situations where textual content is embedded within an image, like a visually appealing quote, and needs to be cross-referenced for origin verification.

Educators can also benefit from this technology by extracting text from scanned pages in textbooks or even photographs of students’ handwritten assignments. The versatility of Copyleaks’ OCR technology extends to compatibility with multiple languages and common image file formats such as jpg, jpeg, bmp, gif, and png.

When text is extracted from an image using the OCR feature, Copyleaks continues to perform plagiarism detection by comparing the obtained content against various online sources and databases. This dynamic approach helps users organize, edit PDF, and convert PDF files with more efficiency, reducing the need for manual data entry and facilitating smoother data mining processes.

Overall, Copyleaks’ integration of OCR technology significantly expands its capabilities as a plagiarism detection program, making it an invaluable tool for detecting copied content in images and providing users with a more versatile solution.

Utilizing the Extract Text from Image Feature

To extract text from images such as scanned documents, PDFs, or other file types like JPG, PNG, and TIFF, use the “Text from Image” feature in the scanning software. First, drag and drop the file or select multiple images from your computer. Then, choose the language for each file or set a default language, such as English, French, German, Chinese, Japanese, or Korean.

The software will then process the images and use an OCR engine to recognize printed and handwritten text, and transform them into digital versions like editable PDFs or Word documents. This feature is useful for offices, healthcare providers handling patient records, and various businesses dealing with labels, receipts, and contracts.

The text recognition process involves image pre-processing, which helps in improving image quality and extracting content from scanned files, transforming formats like PDF, JPEG, BMP, and more into structured data like editable PDFs or text files.

With the extracted text, it’s possible to easily search, manage, and organize the content for various purposes within your organization. Start using the extract text from image feature today and experience its convenience and efficiency.
