10 May 2013 mask2poly Finds a polygon enclosing the user defined mask. Inverse of poly2mask :). Author: Nikolay S.

Hi Daniel.
Thanks for the comment. Unfortunately, it seems to be precise. Too bad I did not knew about the bwboundaries function, before writing my own. bwboundaries seems to works nicely. Out of curiosity can you send me an example of an image where my function fails (I've used it extensively in object tracking without problems)?
Thanks!
04 May 2013 Mosaic generator Photo mosaic generator. Choose a tile image, and a directory with images, and see the magic. Author: Nikolay S.

Hi Nitin
You should either install the app, and pressing the app button will run the mosaic, or run the "NS_mosaic_main.m" function, when the functions folder is in Matlab path. You'll be shown relevant dialog menus- follow the instructions...

Good morning Claz.
You should either install the app, and pressing the app button will run the mosaic, or run the "NS_mosaic_main.m" function.
If running "NS_mosaic_main.m" still shows errors, please send me the error text
Best regards.

12 Mar 2013 Silence removal in speech signals A simple method for silence removal in speech streams Author: Theodoros Giannakopoulos

Excellent submission, works fine on the example, and additional files. Almost what I was looking for. Luckily I’ve checked the File Exchange before I’ve written a version of my own. In my case I’m interested in removing silence gaps form several hours recording from some sort of an audio surveillance device. This way I wish to save listeners time and storage space. A few comments, if I may:
• Why limiting the supported file formats to .wav? “audioread” supports MP3 and many other common audio formats.
• For my case I am not always interested to listen to the segments with voice/audio data, though I’d like to have the option.
• I am interested is storing relevant segments, ignoring silence gaps and irrelevant segments. This naturally demands some dialogs and GUI.
• I’ve noted sometimes speech is not properly detected, I’m still investigating this...
I plan to work on your code, to shape it into the application I want (which is a bit different from the current functionality). As mentioned above your code is an excellent starting point. If you want to, I can share the results later on, perhaps even submitting it.
Keep up the good work!
Thanks!

This is a great idea for a function, but it unfortunately fails in some cases. Matlab has a more robust method built in: bwboundaries.
