# Blue Read

The Blue Read tool is a tool for Optical Character Recognition (OCR). It can perform tasks such as:

- Reading text and characters

- Deciphering badly deformed, skewed, or poorly etched codes

The tool is pre-trained on a database of images that show text in many fonts and backgrounds. The characters of the pre-trained tool:

- Numerals (0-9)

- Uppercase letters (A-Z, except "O")

- Hyphen (-)

- Plus sign (+)

- Ampersand (&)

- Colon (:)

- Forward slash (/)

Since the tool is pre-trained, you can process it without training Training is the process that your tool, which is a neural network, is learning about the features (pixels) based on the labels you made. For example, a tool will learn the defect/normal pixels in each image based on the defect/normal labels you drew. The goal of the tool Training is learning enough to give the correct inspection results of whether an unseen image is defective or not. The key to training is to ensure that you include all possible variations within your training set, and that your images are accurately labeled. Training times vary by the application, tool setup and the GPU in the PC being used to train the network. it first and the tool can almost instantly read characters. The tool already knows how to read characters, you only need to define where in the image to look for characters.
