I am facing an error ie to send plot to a particular IP address using python, numpy and matplotlob. I am attaching snippet which I have tried till now.
Python
import numpy as np
import cv2
from matplotlib import pyplot as plt
img = cv2.imread('ml.png', 1)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
img2 = cv2.imshow('img', img)
cv2.waitKey(0)
corners = cv2.goodFeaturesToTrack(gray, 30, 0.01, 10)
corners = np.int0(corners)
for i in corners:
x, y = i.ravel()
cv2.circle(img, (x, y), 10, 50, 0)
plt.imshow(img), plt.show()
MIN_MATCHES = 15
cap = cv2.imread('mario.png', 0)
model = cv2.imread('mario 3d.jpg', 0)
# create brute force matcher object
bf = cv2.BFMatcher(cv2.NORM_HAMMING, crossCheck=True)
# Compute model keypoints and its descriptors
kp_model = cv2.goodFeaturesToTrack(model, 20, 0.01, 15)
des_model = cv2.goodFeaturesToTrack(model, 20, 0.01, 15)
# Compute scene keypoints and its descriptors
kp_frame = cv2.goodFeaturesToTrack(cap, 20, 0.01, 15)
des_frame = cv2.goodFeaturesToTrack(cap, 20, 0.01, 15)
# Match frame descriptors with model descriptors
matches = bf.match(des_model, des_frame)
# Sort them in the order of their distance
matches = sorted(matches, key=lambda x: x.distance)
if len(matches) > MIN_MATCHES:
# draw first 15 matches.
cap = cv2.drawMatches(model, kp_model, cap, kp_frame,
matches[:MIN_MATCHES], 0, flags=2)
# show result
cv2.imshow('frame', cap)
cv2.waitKey(0)
else:
print
