schestowitzI have a post about it comingJun 04 23:14
schestowitzI've begun showing the tablet (would be same for a phone) some cars which were not included in the training set and it's picking them up correctly most of the time, despite training on just 15 positives and 1000 negatives (commonly called "background"). The pace of processing is 1.5-3 FPS. To get more positives I will need to do manual work or just write a good script (which would not be so trivial as it requires a scanner/Jun 04 23:31
schestowitzparser to pick up and collate pertinent tokens).Jun 04 23:31
