ActionScript 3.0 :: Detect A Color Via Webcam

Aug 16, 2009

I need help with a small flash project i'm doing. Basically the task is to detect a color via webcam, then respond to what colors it can see (using the webcam). Example Color red is held in front of camera - flash sees this, then respond by playing a sound. green and red is held in front of cam, flash can tell there is two colors, plays a sound. etc would writing the webcam video object to a BMD every frame, then getPixel that to work out the colors? I'm guessing i'd need to use colorTransform to merge all the blues, reds, greens, etc together (so it only checks for those 3) then responds if it finds them with getpixel?

is there any examples of that, or something similar i could work from? would anyone be able to give a quick write up of what this might looklike/how to do it? (havent done much programming in as3) All i need it to do is: Check video for range of colours (ie, blue, light blue, dark blue, etc, all are equal to blue, unsure how i'd do this. Was thinking Yellow, Red, Green, Blue as the 4 colours) If any of those are in the video, then respond by playing a sound. (However if yellow and blue are in the video at the same time, play a DIFFERENT tune)

ActionScript 2.0 :: Detect Color Using Webcam?

Aug 9, 2009

Currently making a music project that will, in theory, play sounds based on detected colors a webcam can see.

I'm certain this is possible in either AS 2 or 3 - but unsure exactly how.

I've searched the wonderful nets for a tutorial or an example of this being done with flash but have come up with nothing.

Is there any tutorials for detecting colors and then responding to them? (All as viewed by webcam, so in real-time).

ActionScript 3.0 :: Get Webcam To Detect Colors?

Oct 7, 2009

I'm working on a school project that will work so that a webcam can scan a grid of colors and determine what color it is and there by playing a sound tha is connected to that color. You can then create music by drawing different colors on a grid.I know that this is doable in AS3, I just don't know how exactly since im kind of new to this.So i managed to import the webcam image to flash, and that's all. How do I Proceed?

ActionScript 3.0 :: Implementing A System That Can Detect Night And Day Through Webcam?

Nov 20, 2011

I'm having a bit of trouble implementing a system that can detect night and day through webcam.

I've decided the best approach would be to detect the average colour of the webcam image, and through this it can be converted to grayscale and if its closer to black the background will be dark or if its white it'll be brighter.

What I'm having trouble doing is working out how to achieve this, I've been using the kirupa webcam tutorial but I've got no idea how to actually go about working out the average colour.[URL]..

Webcam - Detect Flash-accessible Camera Without Prompting User For Access To Camera If One Exists?

Oct 11, 2010

From a Flash object, I would like to be able to detect the presence of a webcam that the user might grant access to, without actually asking the user whether they want to grant access. This is to streamline a large application that has extra features if a webcam exists — if there is a webcam, the application will present several dialogs that lead up to the normal cam-security prompt, but if the user doesn't have the hardware, I want to skip over them altogether. Requesting access to the cam before those dialogs won't make sense to the user.

It appears not to be possible to call Camera.getCamera() without the security prompt happening. Is there a workaround? (For instance, could I, perhaps, call getCamera in a hidden Flash object and inspect its return value, or does it block until the user acknowledges the security prompt?)

ActionScript 2.0 :: Auto Detect Most Used Color From Dynamic JPG

Feb 9, 2009

Is it a easy way to detect most used color from one jpg? I worked out a way to do this, however it seems like Flash cant handle large "for-loop" and it lead to calling abandon script during test movie...

I tired this:
1) Dynamic load in a image
2) Use Bitmapdata to register all pixel data into a array (call it A)
3) Convert A into Array B which contain no duplication of value
4) Run through Array A and adding count to see which color appear more than once or so, record it all to an Array C
5) Find out the Maximum number from Array C to determine which is the common used color from the image.

All the above did actually work in the code. My problem is, damn flash seems to handle well with image like 10*10 pixels (100 steps I suppose), swap it with 50*50 will call murder! Anyone come across issue with large "for-loop" and what is the best way to get around this?

ActionScript 2.0 :: Textformat.color - When Call Back The .color Parameter It Shows A Value That Isn't Hex Nor RGB

I'm making a flash app that allows you to create text, edit it. At some point, I need to get the text's color.

[Code]...

Then, you can stick the text on the movie and make a new one. During the creation of the movie clip holding the created text, all the format parameters of the text are passed to the movieclip. When I call back the .color parameter, it shows a value that isn't hex nor RGB... I've been googling for the last hour trying to find how to convert this back to RGB or hex values with no success. In this case, the value is : 65535

ActionScript 2.0 :: Script An Animated Button Of A Square (no Fill) Where On Rollover The Stroke Color Changes From One Color To Another

Hoping someone can point me in the right direction with this. Instead of creating a button and nesting movie clips for each state, I'm trying to script an animated button of a square (no fill) where on rollover the stroke color changes from one color to another (tweening the tint). I want to do this to the button symbol so it's the same for all instances. Is this possible or do I have to go the button > nested MC route? Sorry if this is lame...it's been awhile since I've used Flash and I've forgotten quite a bit.
