Label images on jupyter lab

Thing you want to do

I want to label the images I want to use for AI, but it is troublesome to create a GUI. .. .. I thought I wondered if it could be done on JupyterLab, and I did a lot of research, so I made a note at that time. An image like inputting labeling with input while updating the image displayed with matplot.

Execution environment

code

Label the images in the sample_img folder.

Preparation

import cv2
import matplotlib.pyplot as plt
import os
import glob
import IPython
#Get the path of the image
img_list = glob.glob(os.path.join(r"sample_img","*.jpg "))
img_list
>>> ['sample_img/img3.jpg', 'sample_img/img2.jpg', 'sample_img/img1.jpg']

Code to display the image

name_list = []
for img_path in img_list:
    #Loading images
    img = cv2.imread(img_path)
    #Frame to display image
    fig = plt.figure(figsize=(5,5))
    ax = fig.add_subplot(1,1,1)
    ax.imshow(cv2.cvtColor(img,cv2.COLOR_BGR2RGB))
    plt.title(img_path)
    plt.pause(.01)
    
    #Text box for labeling
    comment = input()
   
    if comment == "break":
        break
    else:
        #Clear the displayed image
        IPython.display.clear_output()
        #Add the string entered in Input to the list
        name_list.append(comment)

The operation screen looks like this. passlabeling.gif

Verification

# name_Check list
name_list
>>> ['dog', 'cat', 'cat']

Finally

I wish I could make the Input part look like a radio button.
