pyplot正在改变图像的颜色

Question

我尝试使用下面的代码绘制一些子图。当我使用OpenCv时图像很好，但是当我使用pyplot时，颜色会改变。 请参阅图片和代码。

用cv2绘图

用pyplot绘制

import cv2
from matplotlib import pyplot as plt

img = cv2.imread('image.jpg')

fig = plt.figure()

ax1 = fig.add_subplot(221)
ax2 = fig.add_subplot(223)
ax3 = fig.add_subplot(224)

ax1.imshow(img)
ax1.set_title('Original Image')



ax2.imshow(imgRedimensionata_proiect)
ax2.set_title('Alg image')

ax3.imshow(imgRedimensionata_traditional)
ax3.set_title('Traditional resize')

fig.show()
cv2.imshow('image',img)
cv2.waitKey(0)

看起来像是在接受BGR并将其显示为RGB（或反之亦然）。添加这样的东西来解决它。

public class AuthenticationSuccessHandler implements AuthenticationSuccessHandler {
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException {
        // Very simple (most probably broken) check if the user is ADMIN or USER
        if (authentication.getAuthorities().stream().filter(a -> a.getAuthority().equals("USER")).findAny() != null){
            redirectStrategy.sendRedirect(request, response, "/profile.html");
        } else {
            redirectStrategy.sendRedirect(request, response, "/admin.html");
        }

        clearAuthenticationAttributes(request);
    }
}
