Haha! My comment was a bit tongue in cheek....but the meaning was there. Two other problems..the Face Off machine.....and the masks on Mission Impossible. ;o) Have a good weekend all!

So you want to allow someone with a picture of you to open your phone? There are more secure ways, like Steven mentioned.

Sry. You never know on here sometimes. I assume your variables are top secret? ;o) Good luck!

I would add actual parameters for dp thru maxRadius. Those are descriptions and have a numeric value. For instance dp should be a 1 or a 2. minDist is the minimum distance between the circles center point in pixels and will vary based on input pic. The HoughCircles docs have all the info. docs

Fine job! No MacPorts or Homebrew needed. Excellent!

Anytime! Sorry it didnt help much. Good luck! I just built the Mac/Linux framework with CMake. Never tried to build the contrib_master.

The key in Xcode is to configure your Search Paths correctly. QT looks similar to Xcode so maybe this will help. In the build/lib folder none of these libraries are added with CMake build, so I just copy/paste those lib's from CMake build into project. Here are some pics of the Header and Library Search Paths config and where I add libraries with copy/paste. Hope this helps. I suppose I could have grouped all the lib's in a folder to make it neater...but I add a little chaos on purpose to break my OCD habit of over organizing. ;o)

What IDE are you using? It is way easier than most make it. Build with Cmake, configure usr and local folders in Xcode, copy paste files from the build/lib folder into Xcode. Done, no MacPorts or Homebrew needed.

So you want computer vision to see in the dark? Maybe incorporate a mag head to read the magnetic ink? Good luck.

Are you using Xcode? Your deployment target is the version of the operation system and should always be set to the highest setting.

If you are looking for an ID from colors, then use whatever gives you the most accurate results. It will be darker without sun, and brighter in the sun. Im not sure how you will adjust for that, plus shadows and so on. Good luck. I would use the license plate for ID, but that is just me.

RYB isnt available as an option, since it is not additive. All I am saying is if you are trying to get a paint formula to mix paint to use in real life, then you have to convert to RYB. You cannot mix paint using RGB, CMYK, HSV or any other computer (additive) colors. Paint uses subtractive color theory. Computers use additive color theory. If you are keeping it digital and the color will never be made in real life, then disregard all I have said.

There is no method. Spend 5 minutes researching RGB to RYB conversion. You need to figure out the processing for yourself.

Total nonsense.

When it comes to opencv, C is like a dial telephone. Obsolete and no longer supported.

If you are trying to achieve a formula to make the color, then you must cross over from RGB to RYB, and that is the tough one. The problem with color is there are additive (paint mixing) and subtractive (computer screen) color formulas. They are very, very different. I came across a formula that was supposed to be it...you could find it with a little Google searching. Computers are too precise..and automotive colors fade with UV exposure.

I just told you how to start trouble shooting. All the coding and interfacing are up to you. No one is going you have your exact configuration...so it is kind of up to you. Good luck.

Isnt it the wrong number of channels? It is looking for 3 and there are 4? Inquiring minds want to know. :o)

Ok., I just looked up raspberry pi, cool interface. I would take a meter and see if the voltage is at the output you connected too when the motor is activated.

It is the relay that turns the motor on, you activate it with your low voltage/wireless input, then it connects the motor voltage and handles the extra amperage for start up and running. Im assuming your computer already emits a signal (wifi, bluetooth) so the trick is to find a controller that can already pick up a wireless signal. DC, AC makes no difference...it is an AMP thing. ;o) It might be easier to buy a small I/O device that has wireless capabilities, then just wire the motor to an Output, and your motor voltage supply to an Input. The small I/O device would also allow you to run the motor backwards so you can pan a camera, which is what I assume you want to do.

You are missing a few components. Find a motor controller that is wi fi or bluetooth capable, then send a signal to that. These guys have all kinds of interface controllers. Numatic Engineering

How did I miss this? It has all my favorite tags. ;o) Im gonna copy/paste link to other question for answer in comments. here You're good now, yes?

Anytime homie! Good luck with your project! :o)

In Xcode. General tab for Target. Scroll to bottom...click + under Linked frameworks and Libraries. Do not add to binaries, this will cause an issue. Xcode automatically adds frameworks to binaries sometimes, delete is from binaries if Xcode adds it. Older versions seemed to work better if you click and drag project into Xcode, then make sure you click the 'copy files' checkbox. Why are you using such an old framework?

The AVCaptureStillImageOutput is what I was thinking about. Now if I can just update Apples code example to make it work correctly. Use this still image for processing.

Ok, I may have to retract my above advice. Im working on this exact thing for OS X. I fired up Xcode for the first time in months to work on it and didnt spend a lot of time, but have yet to find the missing link.

Instead of fighting iOS, use it, and just process with opencv when needed. For example, use iOS for the video (AVCaptureSession), then just grab a frame for processing and use opencv for that frame/pic (GCD). I have a couple of apps that use opencv for image processing. Did I use opencv to pull up a camera interface and so on? No, I use the ImagePickerController and take the pic from it and process it via opencv. The more C++ you insist on using for opencv, the less Swift you can use for iOS since the two are incompatible. For me it is more rewarding to figure stuff out. Instead of bombing this place with a question for every step of your development, spend a month or so sitting in front of your computer for 16 hours a day. You will figure it out.....and will be better off for it.
