6 Sometimes, an entirely new way to approach problems is found. |
|
|
|
7 The media is often fond of covering these topics, be it quantum computing, blockchains, machine learning... |
|
|
|
8 With these big toys come people experimenting with it. |

14 I was expecting to present cute attempts at drawing images with computer-made text, but this is nothing of the sort. |

|
|
|
18 This research paper (no less!) shows that it is possible to write software for placing characters, |
|
|
|
19 later typed during 6 hours by a human operator (for this example). |
|
|
|
20 It is unsettling to see details much smaller than the characters themself be drawn on paper, |
|
|
|
21 along with shades of grey of various intensities. |

28 This is possibly the state of the art of 2010 technology. |
|
|
|
29 It was announced in the yearly conference SIGGRAPH hence presented to an audience full of computer graphics engineers. |
|
|
|
30 The work of three researchers from Hong Kong, Xuemiao Xu, Linling Zhang and Tien-Tsin Wong, shows results of surprising accuracy. |
|
|
|
31 The story does not tell whether there ever was a job offer "looking for ASCII artists for a scientific experiment" posted on the job board of the Chinese University of Hong Kong. |
|
|
|
32 While the paper contains the complete math used, it also illustrates and explains methods to acheive this level of accuracy. |
|
|
|
33 And no, it is not exactly machine learning, but hand-crafted strategies, combined statistics and other data massaging. |
|
|
|
34 After all, it was published five years before things like Tensor Flow were introduced... |

41 Is seven years enough time to improve upon that previous acheivement? |
|
|
|
42 Quoting the previous paper as well as others in its own work, |
|
|
|
43 Osamu Akiyama of the Osaka Faculty of Medicine kept the ball rolling. |
|
|
|
44 This throws the big guns of machine learning to reach higher skies. |
|
|
|
45 Its input data were Japaneses BBS such as 5chan (2chan) or Shitaraba, |
|
|
|
46 which extends the ASCII set to all of unicode, notably the CJK set. |
|
|
|
47 If the result of the paper are not enough to convince you, |
|
|
|
48 the "Bad Apple" often used as a video demo in the Asian market have been converted in its entirety. |
|
|
|
49 Something out of reach if doing every frame by hand. |
|
|
|
50 The TensorFlow and Python code used is released publicly, |
|
|
|
51 and an online demo is offered for the curious. |

62 Is it so futile? Not so sure. |
|
|
|
63 After all, representing anything with a computer is a matter of making a reality fit onto something terribly awkward and unnatural: a display. |
|
|
|
64 The pixels, the square elements praised for providing a grid to throw data at, are promising, but themself have their quirks to be worked around. |
|
|
|
65 For instance, sub-pixel geometry uses the same techniques as those presented by these papers for improving the realism of images beyond what a single pixel can offer. |
|
|
|
66 It is, for ASCII art like for anything else, a matter of representing something, real or fictious, through a medium of some kind. |
|
|
|
67 ASCII art has the ability to fit an image somewhere where there could only be text. |
