Shreya Mehta requested your answer Many scanners include ocr software. what does ocr software do? Optical Character Recognition, OCR. It is one method used to turn analog text, a page of typeset copy or page of old typewriter copy into a digital and editable form, a modern text file or .txt file. OCR is sometimes used inappropriately a decision and choice made by people. OCR software has challenges it makes a lot of conversion errors. It is my opinion that copy converted with OCR requires human proof reading and correction. Software, algorithms and databases are not smart. A human knowledgable in rules of english, punctuation, grammar, mechanics, effective paragraphs, spelling, usage, or what is professional proofreading is vastly superior to software running algorithms and databases at correcting text conversion. Computers and applications need a human overlord with an intact soul. Many business people cut corners and do not take this step. Poor quality text files are the result, all at eventual readers expense. It is hard to believe and difficult to convince many of human capability and the reality that a trained typesetter familiar with computer keyboarding is very fast at keyboarding and accurate at converting analog copy, including handwritten copy such as handwritten manuscripts. 90 words a minute was average beginning typesetter, 120 wpm is better, a select few faster than 120 wpm, but all commonly with 99% to 100% accuracy. Traditionally in a composition workflow, professional typesetting and professional proofreading cycles performed by humans were a quality step that occurred when generating any reading content. Not so much today, written content can lack professional proofreading for typoâs, spelling, usage, and mechanics correction. OCR is only partly to blame for this, so use it when appropriate. Yes humans are the main cause, well the greedy cheap ones that skip proofreading cycles. Check out CAPTCHA since you had questions about OCR then reading and learning about CAPTCHA will bring additional understanding.
Google can't “decode” a computer's voice or any special hardware, yet it finds the image just fine, using the sound. I guess it's pretty weird, right? Anyway, there is no point in hiding that, it's not helpful. So, I'll start over. I'm not a search engine. It's not my job. What I can tell you is that if someone is going to search an image in Google, and that search contains a picture (or other kind of file), the image is just going to appear. There are few conditions to make it appear, and that's basically what I'm going to explain. You have an image that you want people to see. You have the audio of that image. Furthermore, you have the image URL. And you have (with Google's consent) a link that says “download as PDF.” First, if you do not have a file with a picture, it.
