我想在 colab 中使用 cv2_imshow

Question

 import cv2 as cv import numpy as np from google.colab.patches import cv2_imshow from tensorflow.keras.models import load_model img_color = cv.imread('test3.jpg', cv.IMREAD_COLOR) img_gray = cv.cvtColor(img_color, cv.COLOR_BGR2GRAY) ret,img_binary = cv.threshold(img_gray, 0, 255, cv.THRESH_BINARY_INV | cv.THRESH_OTSU) kernel = cv.getStructuringElement( cv.MORPH_RECT, ( 5, 5 ) ) img_binary = cv.morphologyEx(img_binary, cv. MORPH_CLOSE, kernel) cv2_imshow('digit', img_binary) cv.waitKey(0)

This is the process of training a model in handwritten and testing the trained model. I want to load an image using imshow() in colab.

Is there any way to use it without setting the file path?

Answer 1

You can use matplotlib's function for it

fig = plt.gcf()
fig.set_size_inches(18, 10)
plt.axis("off")
plt.rcParams['figure.figsize'] = [20, 10]
plt.imshow(img_binary)
plt.show()
