<pre class="sourcecodebox">CIColorTracking
The CIColorTracking sample application is an Objective-C applicaton that
implements a GPU-based technique to
find the location of a uniquely colored object in a scene and then uses the
position information
to apply video effects.
AppController.h and AppController.m
These files contain a declaration and impelmentation of the AppController
class. This class is a
subclass of NSObject that allows you to control the user interface. The user
interface allows the
user to to select a source movie, change tracking options, view the tracking
video, see a preview
of the mask used for the video, and overlay the mask image onto the tracking
video.
VideoCIView.h and VideoCIView.m
These contain the declaration and implementation for the VideoCIView class
which is a subclass of the
NSOpenGLView class. VideoCIView sets up and manages the OpenGL context that
shows the video.
VideoHandler.h and VideoHandler.m
These files contain a declaration and impelmentation of the Viewhandler class,
which is a subclass
of NSObject. VideoHandler sets up a Core Video display link and manages the
display and context for
the tracking video (which is a QuickTime movie).
TrackingImageUnit is a self-contained project that creates an Image Unit. An
image unit is a
Core Image filter that is packaged as an NSBundle object. Filters packaged as
an image unit are
easy to distribute and use with other applications. This image unit is used by
the CIColorTracking
project, but you can just as easily use the filters in TrackingImageUnit in any
Mac OS X application
by copying the image unit to /Library/Graphics/Image Units. For more
information on creating and
using Image Units and Core Image filters, got to http://developer.apple.com/
and search for
"Image Unit Tutorial" and "Core Image Programming Guide".
TrackingFilters.h and TrackingFilters.m
These files are in the TrackingImageUnit folder and contain the declaration and
implementation for
the TrackingFiltersPlugInLoader class, which takes care of registring the
filters contained in these
files. These files also contain the declaraion and implementation for these
CIFilter subclasses:
CompositeFilter, Centeroid, CoordinateMaskWithColor, MaskFromColor, and
GPUGemsAreaMean.
SYSTEM REQUIREMENTS:
Mac OS X v10.4 or later
Macintosh with Intel or G5 processor.
BUILD REQUIREMENTS:
Xcode version 2.3
Interface Builder version 2.5
RUNNING THE APPLICATION:
When you launch the application, you wil be asked to select a movie to use for
tracking. After the movie opens, click the Tracking Color color well and
choose the color that you want to track in the movie. You can use the loupe
provided by the color picker to precisely select the color. Next set the
Tolerance slider so that the entire object you want to track shows in the Mask
Preview area.
Play the movie by clicking the Play control in the lower right corner. Turn on
Show Composite in Viewer
to see the duck on top of the tracked color object. You see a live preview of
the mask in the preview or
you can overlay it in the main view by setting the opacity of the Overlay Mask.
