handwriting

问题 Hi I have been searching though research papers on what features would be good for me to use in my handwritten OCR classifying neural network. I am a beginner so I have been just taking the image of the handwritten character, made a bounding box around it, and then resize it into a 15x20 binary image. So this means i have an input layer of 300 features. From the papers i have found on google (most of which are quite old) the methods really vary. My accuracy is not bad with just a binary grid

问题 I've been trying to learn about Neural Networks for a while now, and I can understand some basic tutorials online. Now i want to develop online handwritten recognition using Neural Network. So i haven't any idea where to start? And i need a very good instruction. In finally i'm java programmer. What do you suggest I do? 回答1: Start simple with character recognition on the Unipen database. You will need to extract pertinent features out of raw trajectory data in order to form what's commonly

问题 I want to create an application that recognizes handwriting on the screen. I don't need it to recognize insanely difficult words; just simple stuff like "A" "BC" "Z" (maybe some shapes, but could be without this). How do people usually go about this? Are there any famous handwriting recognitions that i can try? 回答1: If you want to recognize single letters and shapes alike I would suggest using GestureOverlayView .

问题 i need some guide lines and help to develop this ANN. i don't have any past experience with neural networks and this is little bit hard for me. i want to recognize handwriting using this.. any help would be nice.. :-| 回答1: This is an open source c# OCR: http://neurondotnet.freehostia.com/samples/ocr.html 来源： https://stackoverflow.com/questions/6403287/hand-written-character-recognition-using-neural-network

问题 I have to implement in an Android application a function that allow me to sign a PDF, when i say "sign" I mean the digital signature (First and second name) affixed to the end of the document from the user. I have access to a Samsung Note 4 (with stylus) then it would not be a problem, "write" on the display. The question is: there is the possibility to sign a document using some library like itext or I must write a custom function ? 回答1: I guess you want to apply an electronic signature on a

问题 Is there any specific algorithm for handwriting recognition? The algorithm should recognize the hand written letter. Any one could help would be greatly appreciated in advance. Thank you 回答1: You can use a genetic algorithm: http://www.foibg.com/ibs_isc/ibs-02/IBS-02-p03.pdf You can use Greedy Point Match: http://www.cs.berkeley.edu/~fateman/msw/GreedyPointMatchWriteup.pdf I would suggest reading this paper: On-Line and Off-Line Handwriting Recognition: A Comprehensive Survey 回答2: OCR might

问题 Can anyone please provide some instructions or steps on how to integrate zinnia (handrecognition system) with regular php? A sample of how it works could be found here. Thank you. 回答1: It says Thread-safe C/C++/Perl/Ruby/Python libraries , so I guess you can't use it with PHP. Place a feature request for PHP wrappers with the project space at sourceforge. 来源： https://stackoverflow.com/questions/1947706/zinnia-handwriting-recognition-and-php-integration

问题 I have a requirement in my iPhone app which is something similar to Handwriting Recognition . I want to give user a space on my view where he can write any character by touch and dragging his finger on the screen and based on what matches with his input the textbox should show the English alphabet. Above is an example of what I want: How should I implement this feature? I am a beginner in this. 回答1: There is no handwriting Frameworks or Libraries currently available. If you are brainy enough

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Is there an open-source implementation in any programming language to detect running handwriting in English and convert them to text ? 回答1: there is Ocropus 来源： https://stackoverflow.com/questions/4130650/opensource-for-detecting-running-handwriting

问题 I have a series of questions about writing code for iOS and including handwritten recognition of japanese. I am a beginner, so be gentle and assume I am stupid ... I'd like to present a japanese word in hiragana (japanese phonetic alphabet), then have the user handwrite the appropriate kanji (chinese character). Then, this is internally compared to the correct character. Then, user gets feedback (if they were correct or not). My questions here revolve around the handwritten input. I know
