Sample Camera Images and 100% Accurate OCR Processing Results with TopOCR!

Here is a collection of sample images from a variety of digital cameras that range in resolution from 1.3 MP to 8.0 MP. We have provided the Tesseract LSTM OCR output processing results in PDF format. We also have provided the original sample images in a .zip file sampleimages.zip (35.5 MB). If you wish, you may download and unpack the .zip file on your local hard drive and open the individual image files in the TopOCR Demo application and verify the results for yourself. With the specified settings, TopOCR's Tesseract LSTM OCR engine is able to read all 8 images with no OCR word errors! Please remember to change the OCR Settings to the camera binarization level below and whatever additional settings or image processing functions are required from the table below.
