for c in contours:
    rect = cv2.boundingRect(c)
    if rect[2] < 100 or rect[3] < 100: continue
    print cv2.contourArea(c)
    x,y,w,h = rect
    cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
    cv2.putText(im,'Moth Detected',(x+w+10,y+h),0,0.3,(0,255,0))
cv2.imshow("Show",im)

how to draw bounding box on image python

Comment

import matplotlib.pyplot as plt
from matplotlib.patches import Rectangle

# load image
img = plt.imread('image.jpg')

# create figure and axis
fig, ax = plt.subplots()

# display image
ax.imshow(img)

# create bounding box coordinates
xmin, ymin, width, height = 50, 100, 150, 200

# create rectangle patch
rect = Rectangle((xmin, ymin), width, height, linewidth=1, edgecolor='r', facecolor='none')

# add patch to axis
ax.add_patch(rect)

# display image with bounding box
plt.show()
