Loading and Preparing Images

First, we load the image using OpenCV:

python
import cv2
img = cv2.imread('your_image.jpg')

Next, we enhance the image for better OCR results, a crucial step known as OpenCV image pre-processing for EasyOCR. Think of it like glasses for the computer!

• Noise Reduction: Removes unwanted spots and blurs.
• Contrast Enhancement: Makes text stand out more clearly.
• Skew Correction: Straightens tilted images, improving accuracy. Skew correction techniques are vital for ensuring OCR engines properly read text. Imagine trying to read a book that's at a 45-degree angle – not fun, right?

Text Detection and OCR Execution

We identify regions containing text:

python
Example: Simple thresholding (more advanced methods exist)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
thresh = cv2.threshold(gray, 0, 255, cv2.THRESH_BINARY + cv2.THRESH_OTSU)[1]

Then, we initialize EasyOCR with the required languages and let it work its magic:

python
import easyocr
reader = easyocr.Reader(['en', 'fr']) # Specify languages
results = reader.readtext(thresh)

Remember to handle different image formats (PNG, JPEG, etc.) and resolutions gracefully – a flexible agent is a useful agent.
