A collection of image processing algorithms that aim to extract the license plate from a car’s photograph taken at parking lots/tolls etc.

The whole process is consisted by 3 parts:

1. Locate the plate inside the photograph
2. Extract each character as a separate part of the photograph
3. Transform the characters to text using OCR

1. Locating the plate inside the photograph

• Convert the image to grayscale
• Apply a sobel mask for later edge detection
• Convert the image to binary by Thresholding
• Calculate edges
• Use the edge to locate the plate

2. Extracting each character as a separate part of the photograph

• Convert the plate image to binary by Thresholding
• Calculate edges
• Use the edges and extract the characters

3. Transform the characters to text using OCR
