Any news on Baduk Cap Pro?

I decided to postpone the separate Pro-App and offer the new feature for live capture of a game as an in-app purchase, so that it is also available for existing customers.

During the last year, I have been busy mainly with improving the reliability of the automatic move recognition. As soon as this is ready, I will release a first version with Baduk Cap 5.0.

To ensure a smooth experience during live capture, Baduk Cap 5.0 will only be downloadable on 64 bit devices (devices that are able to run iOS 11 - iPhone 5s / iPad Air or later).

Sounds cool. Do you have any ideas on a time-table?

That depends on how well the next round of testing goes and how quickly I can find someone for the Korean translation.

Baduk Cap 5.0 is now available for download!

The update includes:
- Improvement of the scoring algorithm
- 'Game recording' (In-app purchase): Capture your game while it is being played!

Apologies to everyone who I kept waiting for so long. When I made the announcement for a game recording feature, I had a working prototype and expected this to be ready for shipment much sooner. However, getting the move recognition to acceptable reliabilty turned out to be a lot trickier than I thought.

Anyway, no efforts have been spared so that you can record your games without any manual interaction and thereby fully concentrate on the game, instead of having to fiddle around with pen and paper or manually input moves on your tablet or phone - which takes away some of your time and concentration and becomes impractical in a tournament situation, once you get under time pressure in the later stages of the game.

There are two modes:
- Automatic move recognition: Analyses the video stream for moves that have been played - the SGF is constructed in real-time.
- Automatic photos: Shoots photos at certain time intervals, for example every 20 seconds during the maintime duration of 1:15 hours and every 10 seconds afterwards. Moves can be edited manually, according to the photos, after the game has ended.

Both modes can also be combined: in the above example, a photo would be taken if the automatic move recognition has not detected a move for 20 seconds during maintime or at least every 10 seconds afterwards.

Battery consumption:
While automatic move recognition has a high battery consumption and requires an external battery pack to record multiple games, e.g. during a tournament day, automatic photos will only switch on the camera when needed for taking the photo, thereby reducing battery consumption to a minimum. I recorded a game with maintime 1 h for each player and the above described settings for automatic photos and still had 76 % battery power left afterwards.

All recorded games are saved on the device with moves and photos and can be manually edited at any later point in time, before exporting the SGF.

Regarding mounting of a phone above the board, I can recommend this holder. It attaches nicely to the table edge and its stability is just fine.

I hope you enjoy the new feature! If you have any feedback, feel free to contact me via email.


One final remark: As of version 5.0, Baduk Cap is 64 bit only and can be downloaded only on devices that are able to run iOS 11 (iPhone 5s / iPad Air or later).

Just bought the app, and I love it. I tried to live capture a video lesson from YouTube. The video of the board starts at 3:15.

https://www.youtube.com/watch?v=o2Z6_H_ ... J&index=32

But, it didn't work. It never recognized any stones. I've attached a photo of my attempt below.

Has anyone had any luck trying to do this?

Ideally, I would like to download the video from YouTube then load it in to Baduk Cap for processing. Would something like that be possible? A similar feature already exists for still photos.

This is an interesting use case … thanks for posting your setup! :-)

Regarding the YouTube video, it does not work for two reasons:
  • The video quality is rather poor (240p) and not sufficient for the current recognition algorithms
  • When variations are shown, multiple stones are removed from the board. Baduk Cap only supports removal of the last played stone.

At the moment, I am working on image recognition improvements - that might help with the first issue.
Enabling variations, however, would introduce a lot of complexity, both in the program and on the UI, and I currently do not see enough demand to justify that.

Version 5.5 is available:

Baduk Cap now incorporates machine learning to achieve a significantly higher accuracy of the stone recognition.

With the currently used model, the reliability increases by a factor of 10.


Because of the leveraged CoreML programming interface, the update requires iOS 11.

It is time for an update about recent enhancements (versions 5.5.1 - 5.6):

  • Settings have been removed from the central settings app and can now be adjusted directly within Baduk Cap
  • You can tap and hold a photo that you have taken (or imported from the photo library), move it around and discard it by tossing it away from the screen. This brings you back to the first screen with the instructions, settings and credits. (To undo, shake the device)
  • It is now easier to accurately position the grid corners, which is especially useful on the small iPhone screen - after adjusting a grid corner with help of the magnifier, release your finger quickly to keep the current position
  • Capture of problems from books:
    - the available screen estate will now be used to full extent for display of the recognized board corner
    - improvement of the recognition algorithm
  • Live Capture:
    - when you scroll through the moves of a recorded game, you now get haptic feedback
    - improvements to the move recognition and editing of a recorded game

As the number of downloads did not correspond to the efforts involved, I have decided - with a heavy heart - to discontinue the Korean localization.

Furthermore, the In-App Purchases for the ‚Scoring‘ and ‚Game recording‘ features are now available as non-renewing subscriptions with a one year duration.
