Description

Brightest Spot Detection in an Image using Python and OpenCV

 First apply a Gaussian blur to the image to remove high frequency noise. This way, even pixels that have very large values (again, due to noise) will be averaged out by their neighbors. To finding the brightest spot in an image is to use the cv2.minMaxLoc  function without any pre-processing. This function requires a single argument, which is our grayscale image. Then, this function takes our grayscale image and finds the value and (x, y) location of the pixel with the smallest and largest intensity values, respectively.
