About\nimagerExtra is an R package for image processing based on the R package [imager](https://github.com/dahtah/imager).\n\n\nimagerExtra provides advanced functions for image processing.\n\n\nSee the vignette [Getting Started with imagerExtra](https://cran.r-project.org/package=imagerExtra/vignettes/gettingstarted.html) to know what functions imagerExtra provides. \n\n\nSee the [introduction of imager](http://dahtah.github.io/imager/) if you don't know imager.\n\n\nSee the [vignette of imager](https://CRAN.R-project.org/package=imager/vignettes/gettingstarted.html) if you aren't familiar with imager.\n\n\n## Installation\nYou can install imagerExtra from CRAN or GitHub.\n\n\nRun the following R code to install imagerExtra.\n```r\n# install from CRAN\ninstall.packages(\"imagerExtra\")\n# install from GitHub\ndevtools::install_github(\"ShotaOchi/imagerExtra\")\n```\n\n## Optical Character Recognition (OCR)\nYou need the R package [tesseract](https://github.com/ropensci/tesseract#tesseract) to do OCR with imagerExtra.\n\n\nSee the [installation guide of tesseract](https://github.com/ropensci/tesseract#installation) if you haven't installed tesseract.\n\n\nHere is a small demo that shows imagerExtra can expand the scope of the application of tesseract.\n```r\nlibrary(imagerExtra)\n# OCR doesn't work well for degraded images\nplot(papers)\nOCR(papers)\n# OCR works well for images with high contrast and little noise\nhello \u003c- DenoiseDCT(papers, 0.01) %\u003e% ThresholdAdaptive(., 0.1, range = c(0,1))\nplot(hello)\nOCR(hello)\n```\n\n\n## Contribution\nYou can create issues for any bug report or suggestion on the [issues page](https://github.com/ShotaOchi/imagerExtra/issues).\n\n\nYou're welcome to fork this repository and send me a pull request for bug fixes or additional features.\n\n\n## Development Blog\nURL of development blog of imagerExtra is
