Problem Definition

1. Create a grayscale image of your face by converting your color image using one of the conversions we discussed in class last week.
2. Flip your face image horizontally, i.e. left to right, right to left.
3. Come up with a third way of manipulating your face that produces an interesting output.

Method and Implementation

I use OpenCV 4.1 on a Mac OS X with Xcode as my IDE to finish this task.

• I used a weighted combination of RGB channel (0.114*R+0.587*G+0.2989*b) to simulate grayImage
• I flip the image by flip the vector.
• I blur the image by average 8 nearby pixels, which is repeated for 5 times

Results

• original:
• gray:
• flip:
• blur:
