# TODOO
|
|
||||||
|
|
||||||
[x] fix get_avg_color
|
|
||||||
[ ] make rasterizer function return a grayscale image rather than rgb
|
|
||||||
[x] implement score function: (image, mask: grayscale) -> score number
|
|
||||||
[ ] resize font to be size of character bounding box
|
|
||||||
[ ] implement a final function check: (image) -> which font it probably is
|
|
||||||
[ ] test(run it in a loop for the result)
|
|
||||||
|
|
||||||
|
|
||||||
## In case results are bad
|
|
||||||
|
|
||||||
[ ] modify score system to use squared error rather than normal error
|
|
||||||
[ ] noramlize the mask before use
|
|
||||||
[ ] if still bad, maybe contact professor for improvement idea?
