| Nov 3, 2016 at 18:48 | comment | added | Martin Rosenau | JPEG is an image format which is very hard to read when not using a special library. "Divide the size of the program by 100" is not a good idea when allowing programs having less than 50% correctness: A program simply writing random numbers will already have something about 10% correctness and its possible to do this within less than 1000 bytes (-> positive score); a program really evaluating images surely will need more than 10000 bytes (-> negative score). | |

| Jan 13, 2015 at 10:34 | comment | added | r3mainer | @trichoplax Yes, they would be standard right-handed dice. I can't see the point in announcing a subset of images for testing, since this would only benefit latecomers | |
| Jan 12, 2015 at 23:37 | comment | added | trichoplax is on Codidact now | If the handedness/chirality of the dice is also guaranteed to be consistent then identifying 2 visible faces will uniquely determine the 3rd visible face, as a double check or to fill in unreliable data. I think it's worth stating explicitly whether the dice will be of consistent handedness. People can of course work this out for themselves by examining the image set, but it would be good to know for certain whether that is meant to be a reliable feature of the images. | |
| Jan 12, 2015 at 23:35 | comment | added | trichoplax is on Codidact now | Can we assume these are all standard dice, so any two opposite faces add up to 7? This would allow double checks such as 3 and 4 can never be on adjacent faces, and 6 and 1 can never be on adjacent faces. | |
| Jan 12, 2015 at 23:33 | comment | added | trichoplax is on Codidact now | You could post 1000 cases and then announce the subset of 100 that will be used for scoring. | |
| Jan 9, 2015 at 22:10 | comment | added | TheNumberOne | @squeamishossifrage I meant so that people can generate more test cases if 100 isn't enough. | |

| Jan 9, 2015 at 20:15 | comment | added | r3mainer | @TheBestOne The Python script doesn't do anything exciting. It just places two dice in the camera's field of view with randomly selected faces pointing up, then gives then a random z-axis rotation from 0 to 2π (repeating the process if the two bounding boxes intersect). I added a little devilry at the post-processing stage (pincushion distortion, glare FX and depth of field blurring) to better simulate the output of a real camera and foil solutions that expect images with perfect geometry, but none of this takes place in the Python script. | |
| Jan 9, 2015 at 20:02 | comment | added | r3mainer | @MartinBüttner Good points. I'll re-tag this as a code challenge. I'm trying to come up with a scoring system that prefers innovative hacks over long-winded but 100% correct solutions; if you can suggest any improvements then please do. I've just generated a set of sample images. In most of them, the two dice are non-overlapping, so it should be possible to score reasonably well without going overboard on the segmentation. | |
| Jan 9, 2015 at 13:36 | comment | added | TheNumberOne | (b) Maybe you could post your script in addition. | |
| Jan 9, 2015 at 11:20 | comment | added | Martin Ender | a) Either one or two dice seems fine to me. b) You should be able to upload the zip file into a Gist on GitHub. c) As far as I can, this is a code challenge and not a code golf. The golf score seems negligible in comparison to the accuracy score, and will probably serve mostly as a tie breaker. (And I think that's good.) | |
