This code applies Gaussian Blur to an image using the OpenCV library. Here's a breakdown of the code:

• cv2: It refers to the OpenCV library, a popular open-source computer vision and image processing library.
• GaussianBlur: This is a function in OpenCV used to apply Gaussian Blur to an image, which helps in reducing noise and smoothening the image.
• gray: This is the input image, which is assumed to be in grayscale format.
• (7, 7): These are the dimensions of the Gaussian kernel, which defines the size of the filter used for blurring. A larger kernel size will result in a more significant blur effect.
• 0: This is the standard deviation (sigma) of the Gaussian distribution used to create the kernel. A value of 0 means that the standard deviation will be calculated automatically based on the kernel size.

So, the code takes a grayscale image gray, applies Gaussian Blur using a 7x7 kernel, and returns the blurred image.
