cv2.equalizeHist is a function in OpenCV (Open Source Computer Vision Library) that performs histogram equalization on an image. Histogram equalization is a technique used to improve the contrast of an image by spreading out the intensity values over the entire range.
The function takes a grayscale image as input and returns the equalized image. It works by computing the histogram of the input image and then applying a transformation function to redistribute the pixel values. This results in a brighter and more contrasted image.
The syntax for using the cv2.equalizeHist function in Python is as follows:
```python
equalized_image = cv2.equalizeHist(image)
```
where `image` is the input grayscale image and `equalized_image` is the resulting equalized image.
