Image-Acquisition-from-Web-Camera

AIM:

To write a python program using OpenCV to capture the image from the web camera and do the following image manipulations. i) Write the frame as JPG ii) Display the video iii) Display the video by resizing the window iv) Rotate and display the video

SOFTWARE USED:

Anaconda - Python 3.7

ALGORITHM:

Step 1:

Use cv2.VideoCapture(0) to access web camera

Step 2:

Use cv2.imread to read the video or image

Step 3:

Use cv2.imwrite to save the image

Step 4:

Use cv2.imshow to show the video

Step 5:

End the program and close the output video window by pressing 'q'.

## i) Write the frame as JPG file
import cv2
videoCaptureObject = cv2.VideoCapture(0)
while (True):
    ret,frame = videoCaptureObject.read()
    cv2.imwrite("jai.jpeg",frame)
    result = False
videoCaptureObject.release()
cv2.destroyAllWindows()



## ii) Display the video
import cv2
videoCaptureObject = cv2.VideoCapture(0)
while(True):
    ret,frame = videoCaptureObject.read()
    cv2.imshow('myimage',frame)
    if cv2.waitKey(1) == ord('q'):
        break
videoCaptureObject.release()
cv2.destroyAllWindows()



## iii) Display the video by resizing the window
import cv2
import numpy as np
cap = cv2.VideoCapture(0)
while True:
    ret, frame = cap.read() 
    width = int(cap.get(3))
    height = int(cap.get(4))
    image = np.zeros(frame.shape, np.uint8) 
    smaller_frame = cv2.resize(frame, (0,0), fx = 0.5, fy=0.5) 
    image[:height//2, :width//2] = smaller_frame
    image[height//2:, :width//2] = smaller_frame
    image[:height//2, width//2:] = smaller_frame 
    image [height//2:, width//2:] = smaller_frame
    cv2.imshow('myimage', image)
    if cv2.waitKey(1) == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()




## iv) Rotate and display the video
import cv2
import numpy as np
cap = cv2.VideoCapture(0)
while True:
    ret, frame = cap.read() 
    width = int(cap.get(3))
    height = int(cap.get(4))
    image = np.zeros(frame.shape, np.uint8) 
    smaller_frame = cv2.resize(frame, (0,0), fx = 0.5, fy=0.5) 
    image[:height//2, :width//2] = cv2.rotate(smaller_frame,cv2.ROTATE_180)
    image[height//2:, :width//2] = cv2.rotate(smaller_frame,cv2.ROTATE_180)
    image[:height//2, width//2:] = smaller_frame 
    image [height//2:, width//2:] = smaller_frame
    cv2.imshow('myimage', image)
    if cv2.waitKey(1) == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()
