OCR and Language Data Support Files

Support for OCR Language data files

The OCR Language Data support files contain pretrained language data files from the OCR Engine page, tesseract-ocr, to use with the ocr function. You can download the additional language files using either the visionSupportPackages function or on the MATLAB® home tab, in the Environment section, click Add-Ons > Get Add-Ons.

GPU processing is supported on CUDA®-enabled NVIDIA® GPUs with compute capability between 2.0 and 6.1. Use the gpuDevice (Parallel Computing Toolbox) function to determine the compute capability of your GPU.
