-In this laboratory experience, you will work with various concepts and basic skills of image editing. We have provided a simple graphical user interface that allows the user to load an image and invert it vertically and horizontally. Your task is to create and implement a function to convert the colored image into an image with gray tones, and another function that converts the colored image into a black and white image.

  `gray = (red * 11 + green * 16 + blue * 5)/32 ;` where `red`, `green` and `blue` are the values for the tones of the red, green and blue colors in the pixel of the original colored image, and `gray` will be the assigned color to the red, green, and blue colors in the pixel of the edited image.

 2. Complete the `GreyScale` function in the `filter.cpp` file to implement the grayscale algorithm. The function should produce a result similar to that in Figure 3, where the image on the left is the original image and the one on the right is the edited image.
