Retrieve Image as a BLOB from MySQL Table using Python

 # Import the required modules
import mysql.connector
import base64
from PIL import Image
import io

# For security reasons, never expose your password
#password = open('password','r').readline()

# Create a connection
mydb = mysql.connector.connect(
host="host",
user="suriyaparithy",
password="suriyaparithy",
database="database" # Name of the database
)

# Create a cursor object
cursor = mydb.cursor()

# Prepare the query
query = 'SELECT PICTURE FROM PROFILE WHERE ID=100'

# Execute the query to get the file
cursor.execute(query)
data = cursor.fetchall()

# The returned data will be a list of list
image = data[0][0]

# Decode the string
binary_data = base64.b64decode(image)

# Convert the bytes into a PIL image
image = Image.open(io.BytesIO(binary_data))

# Display the image
image.show()

Image File stored as a BLOB in MySQL Table using Python

 # Import the required modules
import mysql.connector
import base64
from PIL import Image
import io

# Create a connection
mydb = mysql.connector.connect(
host="localhost",
user="suriyaparithy",
password="suriyaparithy",
database="database" # Name of the database
)

# Create a cursor object
cursor = mydb.cursor()

# Open a file in binary mode
file = open('chemical.PNG','rb').read()

# We must encode the file to get base64 string
file = base64.b64encode(file)

# Sample data to be inserted
args = ('100', 'Sample Name', file)

# Prepare a query
query = 'INSERT INTO PROFILE VALUES(%s, %s, %s)'

# Execute the query and commit the database.
cursor.execute(query,args)
mydb.commit()

Extract text from a single image using Python

#Extract text from a single image using Python
from PIL import Image
from pytesseract import pytesseract

Extract only images from PDF using Python

 # How to Extract Images from PDF in Python
import fitz # PyMuPDF
