abbyyr's Introduction

Access Abbyy Cloud OCR from R

Easily OCR images, barcodes, forms, documents with machine readable zones, e.g. passports, right from R. Get the results in a wide variety of formats, from text files to detailed XMLs with information about bounding boxes, etc.

The package provides access to the Abbyy Cloud OCR SDK API. Details about results of calls to the API can be found here.

Installation

To get the latest version on CRAN:

install.packages("abbyyR")

To get the current development version from GitHub:

# install.packages("devtools")
devtools::install_github("soodoku/abbyyR", build_vignettes = TRUE)

Using abbyyR

To get acquainted with some of the important functions, read the vignettes:

# Overview of the package
vignette("introduction", package = "abbyyR")
# some functions are used along with output
vignette("example", package = "abbyyR")
# how to scrape text from a folder of images
vignette("wiscads", package = "abbyyR")

The final output quality varies by complexity of the layout to resolution to font face etc. To measure the final quality of ocr, you can measure the edit distance to `gold standard' coded sample using recognize. To do quick edit distance based search and replace to fix messy data, you can use turbo search and replace.

abbyyr's Issues

File name in downloaded files using getResults()

The name of the downloaded files are the IDs of the file in listTasks(). Names are not meaningful and does not contain the file extension. Is there any way to keep the name of files in the 'description' as stored in the sample C# app below:
http://ocrsdk.com/documentation/code-samples/dotNet.zip

Then the name can be taken from description and extension could be appended against each file.

ocrFile() error

Hi.

When trying to use the ocrFile() function, I enter the below syntax:

ocrFile(file_path="~/#R_Projects/officeR/ImageOnly.pdf", output_dir="~/#R_Projects/officeR/abbyyR/", exportFormat = "pdfa", save_to_file = TRUE)

However, I get the following error: Error in curl_download(finishedlist$resultUrl[res$id == finishedlist$id], : Argument 'url' must be string.

I found a response to a similar issue at stackoverflow, but running that syntax didn't help either.

Not sure what is going wrong. Any help is greatly appreciated.

trouble using ocrFile()

I'm attempting to use the ocrFile() function to read pdf image of a table. If I use Abbyyr's "finreaderonline.com" with my pdfs I get a nice .csv table back.

When I use ocrFile() I get the following error message:
Error in Ops.factor(res$id, listFinishedTasks()$id) : level sets of factors are different

If I run getAppInfo()
getAppInfo() Name of Application: 1 No. of Pages Remaining: 1 No. of Fields Remaining: 1 Application Credits Expire on: 1 Type: 1

Any ideas about what I could check?

Error: HTTP failure: 403

I've got the error below.

Brief description of the problem

library(abbyyR)
setapp(c("tidyverse", "password"))

getAppInfo()

Error: HTTP failure: 403

Region option is not enabled for processImage() function

In processImage():

querylist <- list(language = language, letterSet = letterSet, 
    regExp = regExp, textType = textType, oneTextLine = oneTextLine, 
    oneWordPerTextLine = oneWordPerTextLine, markingType = markingType, 
    placeholdersCount = placeholdersCount, writingStyle = writingStyle, 
    description = description, pdfPassword = pdfPassword)

This omits the "region" parameters as per https://ocrsdk.com/documentation/api-reference/process-text-field-method/

Hence OCR on a region cannot be done.

ocrFile and processImage return 'Error: HTTP failure: 450'

Hello,

I'm getting the 450 error when working with both processImage and ocrFile functions. As far as I can tell, it does not depends on my app limitations nor my code repository connections, since I'm able to run all other functions that do not provide an immediate file download (such as submitImage, processDocument, etc..).

Also, I think these errors depends on some recent update in abbyyR package or in Abbyy cloud service, since I was able to run those functions up until April/May and I found the same issue posted on Abbyy forum in June (but no proper answer was given to that in the forum).

Any idea of what may be going on?

Thanks
Luca

New HTTP error 450....

Hello,

Thanks for making available your package to test Abbyy OCR.
I am processing a bunch of OCR images. I was able to submit around 100 images following the example you includes in this vignnete:

https://cloud.r-project.org/web/packages/abbyyR/vignettes/wiscads.html

But suddenly stops and responds with Error: HTTP failure: 450.

From that moment on, I cannot process any other image and even I get the same error with deleteTask() but not with listTasks(). I changed the way to connect to Internet with a mobile connection and it seemed to work again, but after submitting the 100 images, again the same problem with the same error.

I saw what you responded in this issue https://github.com/soodoku/abbyyR/issues/1 and I updated CRAN version with the one you have here in GitHub, but the problem persists.

If you know any workaround or alternative....

[1] TRUE

Just curous that is there any connection of your apps related to Microsoft since abbyyR is a web-base application I though? Any solution?
