Re: Sight for the Blind for <100$

And here is the solution. replace the contents of /home/pi/a-update.sh with the following: #!/bin/sh cd /home/pi/After-Sight-Model-1 git fetch --all git reset --hard origin/master chmod +x *.sh echo "Now run: a-update_core.sh, a-update_voice.sh or a-update_teradeep.sh from the /home/pi/After-Sight-...

Re: Sight for the Blind for <100$

I have integrated the contrast code, and it is much nicer. I have noticed though that when contrast is set to 0 that I get nothing. I had added the zero setting to the cycling in the menu so that it was 0,1,2,3 at the next opportunity, dropping the 0 seems like a plan. Thanks, glad that it worked o...

Re: Sight for the Blind for <100$

Thanks Mike. I have also created a patch for the github code at https://github.com/seeingwithsound/raspivoice/tree/patch-1 and issued a pull request, proposing also to cycle the contrast parameter (whose values now have slightly different semantics) among values 0.0 (no contrast enhancement), 1.0, 2...

Re: Sight for the Blind for <100$

I did not use your code because raspivoice already has a command line flag for changing the contrast. I used this. Please see that it meets the needs. No, it doesn't, or else I would not have bothered. Algorithms are my specialty. I'm currently flashing your image but probably have no time today to...

Re: Sight for the Blind for <100$

After porting the above code snippet you will only be left with an "if (opt.contrast != 0.0) { }" branch where the default value for opt.contrast will now be 2.0. Hi Mike, Below you find the ported code that can simply replace the "if ((opt.contrast != 1.0) || (opt.brightness != 0)) { }" branch in ...

Re: Sight for the Blind for <100$

I will implement a contrast value that provides the experience people are expecting, and will need some feedback for this. A good start is to add twice the difference between each pixel and the average of pixels over a camera frame, while guarding against values below 0 or above 255. I have updated...

That is good news! I'm quite enthused by the wireless capbilities. I'm imagining camera glasses that are wireless, and bluetooth headsets. I couldn't be more pleased, it's definitely a step in a good direction. It appears that the Raspberry Pi 3 is already shipping! http://www.pcworld.com/article/3...

Hi Mike, Concerning increased width or height you may also wish to pay attention to minimizing the dangling of the device when worn on the chest. You could experiment with velcro and various sizes of cardboard tagged to the device to see what works best in this respect. My guess would be that wider ...

Although it is not a replacement for actually playing with The vOICe for Android on an Android device, you can find its supported features, including its "talking face detector", listed and described at http://www.seeingwithsound.com/android.htm
