python-tensorflowHow can I use Python and TensorFlow to create an Optical Character Recognition (OCR) example?

This example will use Python 3 and TensorFlow 2 to create an Optical Character Recognition (OCR) example.

First, we need to install the necessary libraries. We will use pip to install TensorFlow and pytesseract.

pip install tensorflow
pip install pytesseract

Next, we will import the necessary libraries.

import tensorflow as tf
import pytesseract

Now we need to define the image that we want to recognize.

image_path = "path/to/image.jpg"

We will use TensorFlow to pre-process the image and prepare it for OCR.

image = tf.io.read_file(image_path)
image = tf.image.decode_jpeg(image, channels=1)
image = tf.image.resize(image, [28, 28])
image = tf.cast(image, tf.float32)
image = image/255.0

Finally, we will use pytesseract to perform the OCR.

text = pytesseract.image_to_string(image)
print(text)

The output of the code will be the text recognized from the image.

Code explanation

**

1. Install necessary libraries: pip install tensorflow and pip install pytesseract
2. Import necessary libraries: import tensorflow as tf and import pytesseract
3. Define the image to recognize: image_path = "path/to/image.jpg"
4. Pre-process the image: image = tf.io.read_file(image_path); image = tf.image.decode_jpeg(image, channels=1); image = tf.image.resize(image, [28, 28]); image = tf.cast(image, tf.float32); image = image/255.0
5. Perform OCR: text = pytesseract.image_to_string(image); print(text)
