load image in python opencv code example

Example 1: java load image

BufferedImage img = null;

try 
{
    img = ImageIO.read(new File("C:/ImageTest/pic2.jpg")); // eventually C:\\ImageTest\\pic2.jpg
} 
catch (IOException e) 
{
    e.printStackTrace();
}

Example 2: cv2 load image

import numpy as np
    import cv2
    import matplotlib.pyplot as plt
    %matplotlib inline # if you are running this code in jupyter notebook

    img = cv2.imread('/path_to_image/opencv-logo.png',0) # reads image 'opencv-logo.png' as grayscale
    plt.imshow(img, cmap='gray')

Example 3: load img cv2

img = cv2.imread('img.jpg')
