cv2_plt_imshow

Using matplotlib_imshow for images read by cv2

Introduction

One of the major issue faced while using cv2, especially when you are using jupyter-notebooks, is to perform cv2.imshow the kernel breaks. Apart from this, most of the users are comfortable using matplotlib for display, specially its display in notebook using %matplotlib inline magic.

This package provides two of the main function, converting the image to a format more suitable in matplotlib, and plotting the image using matplotlib in the notebooks.

# use cv2_plt_imshow function to plot any image that was read by cv2, but is plotted using pyplot
cv2_plt_imshow(im1)

# Convert the image to be suitable for pyplot format and later use it for plotting using pyplot functions
im2 = cv2.imread('./images/landscape.jpg')
fig, axs = plt.subplots(2 , figsize=(20,20))
fig.suptitle('Vertically stacked subplots')
axs[0].imshow(plt_format(im1))
axs[1].imshow(plt_format(im2))
