thombreSoft · #1

There is a new iOS app, currently in the beta testing phase and I am looking for one more tester, willing to try it out and provide some constructive feedback.

Preconditions:
- preferably iPad mini
- iOS 7 installed
- other Go apps installed (like EasyGo, SmartGo Kifu, ...) which can open SGF files
- account on testflightapp.com (registration is free of charge)

Let me know via PM if you are interested.

Wow!

This looks JUST like what that other iOS app promised but didn’t yet deliver … good luck with, I guess I—and many others—will want to have it ~~when it’s out~~

<edit>

I was so excited when I read this that I oversaw that it is already available NOW :oops:

</edit>

Regards, Tom

I think you mean feel 'free' to buy it and try it out, no? ;-)

Does anybody know if it works?

Hi there. Thomas gave me a promocode so I could review Baduk Cap for What's on iPhone and for L19. I'm still working on a review (just toyed a little with the app) and indeed, it works, and really well. Yesterday I replayed a Go Seigen game (GSG-Hashimoto Utaro from the early 20s) and needed only to correct 3 stones out of the 250 or so in the board. Correcting is really easy (can be done within the app itself after recognition.) I used an iPad Air (which has a better camera than older models of iPads) so results may vary slightly depending on camera quality, but I think not too much (after all, what matters is darkness-clearness of stones.) Also works fine with screenshots from pages and similar things.

I helped Thomas with beta testing on my iPad mini and it worked well -- and I've used it on my iPhone while visiting the Chicago Go Club yesterday, worked without any finagling. It was an Ing board with Ing stones, there wasn't any color adjustment necessary.

As per special request from 9x9 fan Ruben :-)

, Baduk Cap now supports also smaller board sizes:

Baduk Cap 1.1: Support for 9x9 and 13x13

Much appreciated, and works perfectly in 9x9 (and 19x19, I don't have 13x13 board, but if 9x9 and 19x19 work great 13x13 should, too

)

News from the development lab:

Version 1.3 with adjustments for iOS 8 submitted for review - expect around 7 days until available in AppStore

First alpha of Version 2.0 with new Scoring functionality (In-App Purchase) rolled out to testers

Progenitor · **#11**

I just found this app the other day and it is awesome! I was driving myself nuts manually adding full board problems to EasyGo and I remembered a certain app that was supposed to do this but didn't work that well. Searched in the app store and found Baduk Cap.

It worked flawlessly with decent light and a physical board. It also works with a game displayed on a monitor or TV. It even works with print with a little adjustment on the white side. It does struggle a little with the black and white diagrams, but with a light touch it worked well. I was using an iPhone 4 so it was old tech with a crappy camera. I'm certain it will work even better with the exposure tools added to the i6.

One request I have is to somehow figure out a way to capture go problems that only show one corner of the board. I'm not sure how you would program it, but it might work by having a partial board feature that only runs the recognition on one quadrant of the board. I suspect joseki recognition programs do a similar thing where it is ignoring most of the board. For problems you basically only need the top left, but I could also see this as a useful featured if you want to save a local position rather than the whole game.

As it stands the app is well worth the price! With the added scoring and if you can figure out local position capture that would be awesome.

One last thing I just thought of is to possibly be able to anchor the corners to each other so you can move the entire grid as one, or to lock the aspect kind of like the crop feature in a phone. I know you are in your early stages of development so I just want to close out by saying that this app is awesome and has saved me about 8 hours just in one night of using it!

Thanks for the positive feedback - I am glad Baduk Cap has been useful for you. :-)

I will think about your feature suggestions as soon as I find the time to do so.

Finally …

Baduk Cap 2.0 with Scoring (In-App Purchase) - Now available on the App Store

The new scoring functionality enables you to determine the winner and score of a game by taking a picture of the final position and marking dead stones and groups.
Counting the score in earlier stages of the game is also possible, but only manually (without support by a score estimator algorithm).

Defaults for komi and rule set can be configured in the settings for Baduk Cap.

You can try out Scoring before purchase (without display of score and game result).

Version 2.1 is now available and includes an improved recognition algorithm.

As can been seen from the screenshots below, it can now handle brightness differences across the board. For the two sample images (from here), there is only one wrong stone, caused by a stain on the second board.

Also: I am looking for people willing to help with the translation of Baduk Cap to Asian languages (Chinese/Korean/Japanese). Please send me a PM if you are interested.

Yeah - you guessed it right

! ... I am adding more image processing capabilities to Baduk Cap:

The next version 3.0 will include automatic recognition of the grid, making the process of capturing your Go positions almost completely automatic.

thombreSoft · **#17**

I uploaded a video on YouTube showing Baduk Cap on iPhone 4S. It includes these features of upcoming versions:

3.0 (currently in App Store review): Automatic recognition and placement of the grid
3.1: New comparison mode: Overlay
3.2: Board corner recognition for problems

thombreSoft · **#18**

It’s been a while since I announced the addition of more image recognition capabilities. It turned out that implementing that grid recognition was more work than expected - a lot more …
But: No efforts have been spared to make your life even easier when it comes to capturing those go positions! :-)

Out now: Version 3.0

Automatic recognition and placement of the grid - recognizes positions at all stages of the game: fuseki, middle and end game.
Should you have taken a decent photograph where the grid is not found or placed incorrectly, send it to me via email and I will correct the problem or look for improvements in the algorithm. Use the ‚Save image‘ option to get the original image, instead of taking a screenshot (which would include the grid and therefore not be usable for analysis).
Regarding runtime: processing the image requires a lot of computations. Having a current generation device with a fast CPU really helps here. On an iPad Air 2, the two sample pictures take less than 2 seconds to compute. On previous generation devices, runtimes will increase.

Overlay comparison
Overlay photo and calculated board for an easier, in-place comparison - especially useful on the smaller iPhone screens (preferred comparison mode can be specified in the app settings)

Chinese translation
Thanks to Xiang Zhao (author of EasyGo) a Chinese localization is now available.

Great news, thank you!

So this should actually be 3.1 already? Or have you just integrated the feature planned for 3.1 into 3.0? Downloading it currently, haven’t checked it out yet.

Very nice to see folks co-operating

Awesome!

Yes, Tom, this is due to development and testing of grid recognition taking longer than expected - so I started with overlay compare in parallel.
