Matplotlib Plotting Incorrect Colors for OpenCV Images

In Python's OpenCV, images are loaded in the BGR (Blue-Green-Red) color space, while Matplotlib adheres to the RGB (Red-Green-Blue) format. This disparity can lead to distorted colors when displaying images loaded with OpenCV in Matplotlib.

The issue stems from the order of color channels in the images. OpenCV images are stored in BGR format, whereas Matplotlib expects RGB. As a result, the color channels get swapped, leading to incorrect colors being displayed.

Solution:

The most straightforward solution is to convert the BGR image loaded with OpenCV to RGB explicitly before passing it to Matplotlib. This can be achieved using the following code:

<code class="python">RGB_img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)</code>

By performing this conversion, the color channels get corrected, ensuring that the image is displayed accurately in Matplotlib. The resulting image will now match the original source image's colors.
