Read in web cam

What we are trying to do is read in an image from a webcam and scan the image pixals for certian rbg values. we have need to do this about once every sec and delete the image if these value are not found

Satellite L645D-S4029 (PSK0QU-00W009)
The Toshiba downloads for that model are here, Brittney.
This is the correct driver/application for your webcam.

I just puchased a Mac Mini. I have to have a working web cam. The reviews I've been reading don't sound promising. How do I make it happen?

I just purchased a Mac Mini. I HAVE to have a working web cam. I've been reading web cam reviews and I haven't found one that has a Mac driver. It sounds like the performance on Macs are bad. 2 of the reviews are positive. If I understood it right, one guy made some settings changes on his comp. to make it work. I'm new to Macs and can hardly believe that Mackintosh hasn't produced a single portable web cam in all the years they've been in use.

Actually I'm pretty sure that Apple did produce a webcam, tho' it was some years ago. Most USB webcams should work fine. If you HAVE to have one, and know that it will work, then get an Apple Cinema Display or Thunderbolt Display - price tags are pretty hefty tho'!

How do i use my web cam, where do i go to, to get started

Can't figure out where to go to be able to use my web cam. Its not in my devices and printers area.

Firstly, uninstall the current version of Cyberlink Youcam and re-install it.
To Uninstall: Click Start >> type Programs and Features in search and select it from the list >> In there, select Cyberlink Youcam and uninstall it.
Once done, try using webcam with Skype or any other messenger you may have, or else re-install Youcam.
If the above does not work, do a System Restore to a previous working date when the webcam worked.
System Restore: Click Start >> type System Restore in search and select it any perform on-screen instructions to restore the notebook to a previous working date.
If none of the above work, open Device Manager, check if you have 'HP Webcam' listed under Imaging Devices category.
You would find the Product Number on the sticker in the battery compartment, will be similar to XT594PA#ABA.

Capture Web Cam image in APEX and Upload into the Database

Overview
By using a flash object, you should be able to interface with a usb web cam connected to the client machine. Their are a couple of open source ones that I know about, but the one I chose to go with is by Taboca Labs and is called CamCanvas. This is released under the MIT license, and it is at version 0.2, so not very mature - but in saying that it seems to do the trick. The next part is to upload a snapshot into the database - in this particular implementation, it is achieved by taking a snapshot, and putting that data into the canvas object. This is a new HTML5 element, so I am not certain what the IE support would be like. Once you have the image into the canvas, you can then use the provided function convertToDataURL() to convert the image into a Base64 encoded string, which you can then use to convert into to a BLOB. There is however one problem with the Base64 string - APEX has a limitation of 32k for and item value, so can't be submitted by normal means, and a workaround (AJAX) has to be implemented.
Part 1. Capturing the Image from the Flash Object into the Canvas element
Set up the Page
Required Files
Download the tarball of the webcam library from: https://github.com/taboca/CamCanvas-API-/tarball/master
Upload the necessary components to your application. (The flash swf file can be got from one of the samples in the Samples folder. In the root of the tarball, there is actually a swf file, but this seems to be a different file than of what is in the samples - so I just stick with the one from the samples)
Page Body
Create a HTML region, and add the following:
    <div class="container">
     <object id="iembedflash" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="320" height="240">
          <param name="movie" value="#APP_IMAGES#camcanvas.swf" />
          <param name="quality" value="high" />
          <param name="allowScriptAccess" value="always" />
          <embed allowScriptAccess="always" id="embedflash" src="#APP_IMAGES#camcanvas.swf" quality="high" width="320" height="240"
type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" mayscript="true" />
    </object>
    </div>
<p><a href="javascript:captureToCanvas()">Capture</a></p>
<canvas style="border:1px solid yellow" id="canvas" width="320" height="240"></canvas>That will create the webcam container, and an empty canvas element for the captured image to go into.
Also, have a hidden unprotected page item to store the Base64 code into - I called mine P2_IMAGE_BASE64
HTML Header and Body Attribute
Add the Page HTML Body Attribute as:
onload="init(320,240)"
JavaScript
Add the following in the Function and Global Variable Declarations for the page (mostly taken out of the samples provided)
//Camera relations functions
var gCtx = null;
var gCanvas = null;
var imageData = null;
var ii=0;
var jj=0;
var c=0;
function init(ww,hh){
     gCanvas = document.getElementById("canvas");
     var w = ww;
     var h = hh;
     gCanvas.style.width = w + "px";
     gCanvas.style.height = h + "px";
     gCanvas.width = w;
     gCanvas.height = h;
     gCtx = gCanvas.getContext("2d");
     gCtx.clearRect(0, 0, w, h);
     imageData = gCtx.getImageData( 0,0,320,240);
function passLine(stringPixels) {
     //a = (intVal >> 24) & 0xff;
     var coll = stringPixels.split("-");
     for(var i=0;i<320;i++) {
          var intVal = parseInt(coll);
          r = (intVal >> 16) & 0xff;
          g = (intVal >> 8) & 0xff;
          b = (intVal ) & 0xff;
          imageData.data[c+0]=r;
          imageData.data[c+1]=g;
          imageData.data[c+2]=b;
          imageData.data[c+3]=255;
          c+=4;
     if(c>=320*240*4) {
          c=0;
          gCtx.putImageData(imageData, 0,0);
function captureToCanvas() {
     flash = document.getElementById("embedflash");
     flash.ccCapture();
     var canvEle = document.getElementById('canvas');
     $s('P2_IMAGE_BASE64', canvEle.toDataURL());//Assumes hidden item name is P2_IMAGE_BASE64
     clob_Submit();//this is a part of part (AJAX submit value to a collection) two
}In the footer region of the page (which is just a loading image to show whilst the data is being submitted to the collection [hidden by default]) :<img src="#IMAGE_PREFIX#processing3.gif" id="AjaxLoading"
style="display:none;position:absolute;left:45%;top:45%;padding:10px;border:2px solid black;background:#FFF;" />If you give it a quick test, you should be able to see the webcam feed and capture it into the canvas element by clicking the capture link, in between the two elements - it might through a JS error since the clob_Submit() function does not exist yet.
*Part 2. Upload the image into the Database*
As mentioned in the overview, the main limitation is that APEX can't submit values larger than 32k, which I hope the APEX development team will be fixing this limitation in a future release, the workaround isn't really good from a maintainability perspective.
In the sample applications, there is one that demonstrates saving values to the database that are over 32k, which uses an AJAX technique: see http://www.oracle.com/technetwork/developer-tools/apex/application-express/packaged-apps-090453.html#LARGE.
*Required Files*
From the sample application, there is a script you need to upload, and reference in your page. So you can either install the sample application I linked to, or grab the script from the demonstration I have provided - its called apex_save_large.js.
*Create a New Page*
Create a page to Post the large value to (I created mine as 1000), and create the following process, with the condition that Request = SAVE. (All this is in the sample application for saving large values).declare
     l_code clob := empty_clob;
begin
     dbms_lob.createtemporary( l_code, false, dbms_lob.SESSION );
     for i in 1..wwv_flow.g_f01.count loop
          dbms_lob.writeappend(l_code,length(wwv_flow.g_f01(i)),wwv_flow.g_f01(i));
     end loop;
     apex_collection.create_or_truncate_collection(p_collection_name => wc_pkg_globals.g_base64_collection);
     apex_collection.add_member(p_collection_name => wc_pkg_globals.g_base64_collection,p_clob001 => l_code);
     htmldb_application.g_unrecoverable_error := TRUE;
end;I also created a package for storing the collection name, which is referred to in the process, for the collection name:create or replace
package
wc_pkg_globals
as
g_base64_collection constant varchar2(40) := 'BASE64_IMAGE';
end wc_pkg_globals;That is all that needs to be done for page 1000. You don't use this for anything else, *so go back to edit the camera page*.
*Modify the Function and Global Variable Declarations* (to be able to submit large values.)
The below again assumes the item that you want to submit has an item name of 'P2_IMAGE_BASE64', the condition of the process on the POST page is request = SAVE, and the post page is page 1000. This has been taken srtaight from the sample application for saving large values.//32K Limit workaround functions
function clob_Submit(){
          $x_Show('AjaxLoading')
          $a_PostClob('P2_IMAGE_BASE64','SAVE','1000',clob_SubmitReturn);
function clob_SubmitReturn(){
          if(p.readyState == 4){
                         $x_Hide('AjaxLoading');
                         $x('P2_IMAGE_BASE64').value = '';
          }else{return false;}
function doSubmit(r){
$x('P2_IMAGE_BASE64').value = ''
     flowSelectAll();
     document.wwv_flow.p_request.value = r;
     document.wwv_flow.submit();
}Also, reference the script that the above code makes use of, in the page header<script type="text/javascript" src="#WORKSPACE_IMAGES#apex_save_large.js"></script>Assuming the script is located in workspace images, and not associated to a specific app. Other wise reference #APP_IMAGES#
*Set up the table to store the images*CREATE TABLE "WC_SNAPSHOT"
"WC_SNAPSHOT_ID" NUMBER NOT NULL ENABLE,
"BINARY" BLOB,
CONSTRAINT "WC_SNAPSHOT_PK" PRIMARY KEY ("WC_SNAPSHOT_ID")
create sequence seq_wc_snapshot start with 1 increment by 1;
CREATE OR REPLACE TRIGGER "BI_WC_SNAPSHOT" BEFORE
INSERT ON WC_SNAPSHOT FOR EACH ROW BEGIN
SELECT seq_wc_snapshot.nextval INTO :NEW.wc_snapshot_id FROM dual;
END;
Then finally, create a page process to save the image:declare
v_image_input CLOB;
v_image_output BLOB;
v_buffer NUMBER := 64;
v_start_index NUMBER := 1;
v_raw_temp raw(64);
begin
--discard the bit of the string we dont need
select substr(clob001, instr(clob001, ',')+1, length(clob001)) into v_image_input
from apex_collections
where collection_name = wc_pkg_globals.g_base64_collection;
dbms_lob.createtemporary(v_image_output, true);
for i in 1..ceil(dbms_lob.getlength(v_image_input)/v_buffer) loop
v_raw_temp := utl_encode.base64_decode(utl_raw.cast_to_raw(dbms_lob.substr(v_image_input, v_buffer, v_start_index)));
dbms_lob.writeappend(v_image_output, utl_raw.length(v_raw_temp),v_raw_temp);
v_start_index := v_start_index + v_buffer;
end loop;
insert into WC_SNAPSHOT (binary) values (v_image_output); commit;
end;Create a save button - add some sort of validation to make sure the hidden item has a value (i.e. image has been captured). Make the above conditional for request = button name so it only runs when you click Save (you probably want to disable this button until the data has been completely submitted to the collection - I haven't done this in the demonstration).
Voila, you should have now be able to capture the image from a webcam. Take a look at the samples from the CamCanvas API for extra effects if you wanted to do something special.
And of course, all the above assumed you want a resolution of 320 x 240 for the image.
Disclaimer: At time of writing, this worked with a logitech something or rather webcam, and is completely untested on IE.
Check out a demo: http://apex.oracle.com/pls/apex/f?p=trents_demos:webcam_i (my image is a bit blocky, but i think its just my webcam. I've seen others that are much more crisp using this) Also, just be sure to wait for the progress bar to dissappear before clicking Save.
Feedback welcomed.

Hmm, maybe for some reason you aren't getting the base64 version of the saved image? Is the collection getting the full base64 string? Seems like its not getting any if its no data found.
The javascript console is your friend.
Also, in the example i used an extra page, from what one of the examples on apex packages apps had. But since then, I found this post by Carl: http://carlback.blogspot.com/2008/04/new-stuff-4-over-head-with-clob.html - I would use this technique for submitting the clob, over what I have done - as its less hacky. Just sayin.

Capture an image using the web camera from a web application

Hi All,
Could anyone please share the steps what have to be followed for capture an image using the web camera from a web application.
I have a similar requirement like this,
1) Detect the Webcam on the users machine from the web application.(To be more clear when the user clicks on 'Add Photo' tool from the web application)
2) When the user confirms to save, save the Image in users machine at some temporary location with some unique file name.
3) Upload the Image to the server from the temporary location.
Please share the details like, what can be used and how it can be used etc...
Thanks,
Suman

1) Detect the Webcam on the users machine from the web application.(To be more clear when the user clicks on 'Add Photo' tool from the web application)There's not really any good way to do this with JMF. You'd have to somehow create a JMF web-start application that will install the native JMF binaries, and then kick off the capture device scanning code from the application, and then scan through the list of devices found to get the MediaLocator of the web cam.
2) When the user confirms to save, save the Image in users machine at some temporary location with some unique file name.You'd probably be displaying a "preview" window and then you'd just want to capture the image. There are a handful of ways you could capture the image, but it really depends on your situation.
3) Upload the Image to the server from the temporary location.You can find out how to do this on google.
All things told, this application is probably more suited to be a FMJ (Freedom for Media in Java) application than a JMF application. JMF relies on native code to capture from the web cams, whereas FMJ does not.
Alternately, you might want to look into Adobe Flex for this particular application.

How do I use an external web cam with my Mac Pro on Skype?

I am trying to use my MAC Pro with an external web cam (Logitec C615) on Skype. I want to use the external so that I can pan and video a room full of people. Kind of hard to do with the built in cam.
How do I tell the Mac Pro to use the external for Skype and not the built in?

Go to Skype preferences, click on audio/video, and choose your camera from the drop down menu...

How to enable multiple access to a web cam?

Hi... I am using JMF to develop an online monitoring web page with Java Applet.
However, as i tried it just now, when one browser is rendering that page, others can not even lauch the web cam.
I am using Logitech QuickCam. Is it because of the web cam is possessed by one application, and others have to wait? Or the client should also install JMF in order to view the page successfully?
Can anyone please tell me?
Thanks in advace.

Let me get this straight. You have a web application that uses spring framework and hibernate to access the database. You want the user to be able to select the database that he wants to access using spring and hibernate.
Hopefully you are using the Spring Framework Hibernate DAO. I know you can have more that one spring application context. You can then trying to load a seperate spring application context for each database. Each application context would have it's own configuration files with the connection parameters for each datasource. You could still use JNDi entries in the web.xml for each datasource.
Then you would need a service locater so that when a user selected a datasource he would get the application context for that datasource which he would use for the rest of his session.
I think it is doable. It means a long load time. And you'll need to keep the application contexts as small as possible to conserve resources.
