Could anyone please tell me why our HW4 sample result says the image size is 64 x 48 even though ​the image sizes of img_22.ppm and img_20.ppm are both 192 x 144?
Please see the sample result below. Thank you,

 

# Name: John Black
# Target image name: img_22.ppm
# Reference image name: img_20.ppm
# Number of target macro blocks: 4 x 3 (image size is 64 x 48)
