I am running this code in google colab (I also tried at my local). I use only one image and it uses all of the ram. Do I do something wrong? Is it normal to use 16 gb ram? I added %matplotlib inline and it still crashes?
import cv2
import matplotlib.pyplot as plt
import numpy as np
f = cv2.imread('/content/gdrive/MyDrive/grass.png')
f = cv2.cvtColor(f, cv2.COLOR_BGR2GRAY).astype(float)
plt.imshow(f)
plt.colorbar()
def gauss1(sigma, width):
hwidth = round((width-1)/2)
x = np.arange(-hwidth, hwidth+1,1)
g = np.exp(-x**2/(2*sigma**2))
return g/np.sum(g)
g1=gauss1(2,11)
g1=np.reshape(g1,(1,-1))
plt.imshow(g1)
f1 = cv2.filter2D(f,-1,g1)
fig = plt.figure(figsize=(10, 20))
fig.add_subplot(1,2,1)
plt.imshow(f)
fig.add_subplot(1,2,2)
plt.imshow(f1)
It does not even produce last code snippet's output.
Use:
plt.show()
to show the matplotlib output.%matplotlib inline
if you are using any ipython notebook kernel such as jupyter notebooks, google colab or kaggle notebooks.
