is any of this on github? I might be able to contribute.

Detect US Speed limit signs. Does anyone know of any projects, completed or underway to get speed limit signs from a das

did you figure it out? I also am compiling from github to android-studio

did you figure it out?

In AndroidStudio I pulled everything from github aok.

Q: How do I run the puzzle app? I hit DEBUG and got this error:

Error:java: /production/15-puzzle: does not exist

I don't even know what /production means?

What do I do? Thanks for any leads! -cellurl

This is a lame opencv question, but I don't know where to turn.

I am trying to run opencv on my Android Mirror. When I run, it says,

"It seems that you device does not support camera (or it is locked) Application will be closed."

Q: How do I figure out who has locked the camera or how to unlock it. I have root access and am poking around in "adb shell".

But I don't know what is the simplest way to unlock the camera. I have tried to kill apps which typically use the camera, but it hasn't been successful.

I have Android Studio working on it, so perhaps you could suggest a simple app which tells which device has the camera locked open.

Thanks so much for any leads!

soo, if I want to capture more distant cars with the same classifier, I would grab pixels just in the middle and since that is less than the pyramid-smallest, I would have to add (interleave, filter, upsample) to get more pixels between them? Does that make sense? Thanks Steven!

Hi,

When does the Haar function not work?

EG, if I do a digital zoom, will it work? EG, if I have a big face, will it work?

Sorry to ask this, but I am lazy (there I said it).....

does ionroad use opencv?

I prefer Eclipse-Update-Manager to tar files.installation howto using tar files Q: Why must I use a tar file to add this to my existing Java Eclipse?

I say that because last time I tried, it hosed my Eclipse.

Anyway, thanks for any leads....

is there a MASK function I can use? Thanks for responding.

I want to ignore some part of the image rightup front.

For example, I am processing a road-car-video and I just want to process inside the lines. For starters, I assume the lines are fixed in a V shape away from me. The V shape can just be a png file.

How can I do that painlessly?

Thanks for any leads.

I don't understand why the install tutorial shows "SPACE". Oh well. Thanks. That fixed it. For others, this video was also useful. http://www.youtube.com/watch?v=6jSPoBgQPMI Thanks Vladislav! Dunno if tip is available?

I don't know what to do next. Q: Do I have to compile it? How?

I tried this:

$ pkg-config opencv --cflags Package opencv was not found in the pkg-config search path. Perhaps you should add the directory containing `opencv.pc' to the PKG_CONFIG_PATH environment variable No package 'opencv' found

Any leads appreciated! -cellurl

Trying to install on Ubuntu/Eclipse/C++

I am following these instructions: link text

I get this: $ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local

CMake Error: The source directory "/home/jim/workspace/displayimage/opencv-2.4.7/release/CMAKE_INSTALL_PREFIX=/usr/local" does not exist.

Thanks for helping. jim

I only need to know approximate distance such as 10m, 100m, 1000m

I have contacted iOnRoad, Mobieye, Allvision. None of them will add a beacon. This is your opportunity to build something useful.

I need an app telling me the distance to the car ahead. It could be buggy, just working under ideal conditions. Not great, just useful.

The "distance" should be broadcast via a simple Bluetooth Beacon. That way, you sell the product and I use the beacon.

Its for this project summer 2014. link text

Hi,

I am building a car app. It must use the Android camera and tell how far the car ahead is.

I don't even know if opencv is appropriate for this. Some have suggested Android NDK...

Thanks for discussion! jim
