What is the best OCR software on the market?
The Answer is convoluted because there are several of problems that people address. There is a family of OCR systems utilized with batch processing of documents for which semantic analysis is necessary. These OCR get all the in the document are quite a few I have direct experience with ABBY and NSOCR. The latest is pretty flexible and has several built in functions. Other OCR classes are concerned with bar code recognition this is a field of its own maybe someone can respond on this. For mail room scanning in the last few years there has been the advent of intelligent OCR where machine learning algorithms are used for helping recognizing the document layout and the semantic. Companies in this area are Ephesoft and evision. Evision claims they have the best OCR in the market they are also active in the field of PDF Tables to excel conversion . Nuance has also a quite expensive OCR SDK that is know under the brand name of omini page. It is interesting that they have hand writing recognition ( useful in the medical records) and check mark recognition. I havee across specialized solutions for passport reading which is an area of specialization of its own within OCR. Finally OCR online claims to have the cheapest OCR in the market for batch processing. It could be an alternative to Tesseract OCR for those who have moderate budget.
Is there any software (preferably for Mac) that can do OCR on text in images and add this to the image’s metadata/EXIF?
You will just need a OCR program for mac such as Adobe Acrobat PDF Converter OCR ABBYY FineReader OCR Pro they are all designed to ocr scanned files and s into the program by drag and drop PDF files you can add dozens of files at one time.
Why does pytesseract not recognize a text while online OCR services recognize the same image?
Pytesseract uses(wraps) Tesseract OCR. Tesseract does some resolution is not high enough. If neither then the problem is with the layout analysis. Tesseract was originally developed for books.
What's the best machine learning model for text recognition on user interface screenshots?
Currently the best performer is the Tesseract OCR which is also used by Google for to detect and extract from s and then feed them to a LSTM net to generate predictions.
Which is the best opensource library for text detect detection from images?
I think you are looking for Optical character recognition s . Listing the best ones out there. Also I suggest you to go with OCR APIs keeping your app pretty light weight. Tesseract s(software) seems to be a pretty good choice one of the best OCR engines. Fork from github here s . It has a python wrapper pyocr s Best Free OCR API & Online OCR Service s . Using API would be a pretty good choice as all the heavy lifting would be done by an external service. OCR Software from ABBYY. s This one is pretty good. They have an OCR engine and not library. Vision API - Image Content Analysis s by Google Cloud Platform I loved this one. Here aparison of of available OCR libraries Comparison of optical character recognition software s
What is the best OCR software?
The best OCR software is the one thats not just an OCR engine but also has a powerful analytics and machine learning engine toplement it. I have been working with OCR problems for about 5 years now. After dabbling with the usual suspects for a while I figured out that none of the current OCR technologies on their own can provide a robust business solution. In my experience what works best is thebination of machine learning technologies and multiple OCR engines. Different OCR engines have different strengths - some work really great on scanned documents others are good at images captured from mobile. horizontal-rule But once you deploy data science and machine learning technologies on top of the extracted data you land up with something that is way more potent than vanilla OCR. We have used it for capturing personal details off driving licenses & passports Identity Fraud Detection Solution & Platform Extracting details from invoices expenses Mobile Based Receipt Scanning & Data Extraction System and several other use cases. But I do admit even with machine learning we are not able to hit that 1% extraction mark... but it has brought us a lot closer than OCR. For critical use cases where 1% extraction is must we end up supporting it through manual intervention but that % is tiny and constantly shrinking.
What are the best Python scripts you've ever written?
I am aputer engineer with 15 years of experience. I have created multiple python scripts (similar to many scripts described already ) for daily usage tasks. However my best python script would be facebook automation. The setup includes a selenium driver on firefox. The script is triggered once every 6 hours on a dedicatedputer. The scripts opens web browser and logs in with my account. Some of thing it can do are listed Parse my full friend list and create an xml with all relevant details. (This is important as later steps take action only on feeds from people in this created xml.) Scroll the feedpage and take actions on individual feeds. By default it will like any profile pic cover pic change. If other people congratulate my friend it can parse thement like the feed andment congratulation message. I am anonymous because most likely it against facebook policies to use this kind of scripts for daily interaction. EDIT 1 This edit section is for people who are interested in knowing how the whole script works. I will try to keep it minimal so that it doesn be too technical. The script has 3 main work areas Navigation Navigate to a webpage scroll the page etc. Action Take some action on specific element based on info collected. ordered-list Navigation Selenium driver gives the direct capability to launch a browser navigate to a scroll down etc. Hence this part is pretty much straight forward. Info collection This is one of the most hard parts. On firefox you can right click any element and inspect it . Inspect Element gives details of what the html code for an element looks like Here is a snapshot of what firefox shows when i inspect a friend name in my friends list. The class of div element is very important. I now know that whenever i will parse an element of this class it will have the details of my friend (name etc ) I first statically find these elements manually and then hardcode them in my script. I can now parse necessary elements and collect the information present in those via selenium. Selenium gives the api to extract each information of an element. For e.g. I can extract the href in above picture and i can save the of my friend. This example also covers first point of my script of how i created xml of all my friends. I need to parse my friends list only once and save it for future use until i add a friend. In a similar way we can parsements count events etc . Action Once we have collected the information we can apply our own programming logic to that information. For e.g if someone hasmented Nice picture we can post a similarment. Selenium provides the api to click on element in a area etc. So for like we simply click on Like element with that specific class. That all folks.
Can any one suggest me the best open source OCR Services?
