I know about face.com and its cool API. But it only identifies the people in the photo. I really dont need that. I want to able to detect the position (as in x,y,width and height) of face(s) in a given 2d photo. If anyone know of an ongoing project, of available projects, please help me out with some links, tips and or advice. Deeply appreciate that. Thanks
Use OpenCV Face detector. It gives x,y,width,height

![enter image description here][1]please I need some help, this should apparently be something very simple and basic to do, but maybe I'm missing something.
I'm quite newbie to Unity3d, I had no much problem with creating a somewhat flashy 2.D scene (I mean 2D with different layers in Z level), scripts, etc. But I'm having trouble to create a "UI Slider" object: when I create it, it just shows nothing on screen. How can I make it visible? I just need to create a very simple, plain slider whose value can be controlled at runtime by means of a script.
thanks.
Well.. since you give nothing to go on, I suggest that you take a look at a tutorial for the UI:
https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/using-the-ui-tools
If you have troubles after this tutorial, come back with an example of your problem to make people more willing to sacrifice their time in helping you.
Hope this is somewhat useful
Take a look at the Unity3D docs here.
http://docs.unity3d.com/Manual/script-Slider.html
It should have what you are looking for.
I am trying to rotate a UIButton so it looks more like a diamond instead of a square. I have searched a lot on the site and could not find anything that could help me. I am having a lot of trouble with this and need some help. I think it will increase the appeal of my app when it is running. This is a problem I have had for a while and have been struggling with so anything can help me. I don't know if this is a built in feature in Xcode or if I need to do this programmatically.
Any suggestions would be greatly appreciated.
Thanks in advance.
You could simply apply an affine transform to the button. Something like this:
import Darwin
...
myButton.transform = CGAffineTransformMakeRotation(M_PI/2)
However, that will rotate the entire button, including the title. If that's not what you want then it gets more complicated.
I know it's something with texture.needsUpdate() while rendering but I don't have a clue how to actually implement it. Maybe someone knows a link where I can see a working example or post some piece of code? Cheers.
An excellent question; I created some sample code to do exactly this -- using a spritesheet to do some 2D animation on a plane and on a cube, which requires regular updates. Here is a link to a documented example, that in particular contains a function to do exactly what you need.

Hope it helps!
I need some help finding a graphic library for Windows Mobile 6 with a control to answer some quick Yes/No questions.
Something like what's shown here
Also, I need to do something like this.
I don't need to present it the information in the exact same way but that would definitively be a plus.
Thank you very much in advance. Any help will be appreciated.
The way I did it at the end was how josef said, I wrote my own control for the Yes/No answers and I designed a static class to draw over a predefined image with the format already stablished (I just draw the lines indicating what the driving did at a particular time)
Does anyone know of a Ruby library that can list all of the colors in a photo, as well as listing them in order of frequency? Or is it possible that RMagick already can do something like this?
If no one knows of one, how exactly could I get started on making such a tool? I have a great idea for a program I'd love to try, however I just don't know much about image processing as I've never done it.
I'd be very grateful for any tips or info to point me in the right direction! Thanks!
