39 * @brief This class provides methods to generate individual feature data from an individual image data and collect to feature set file.
43 * The %ImageFeatureManager class provides methods to generate individual feature data from an individual image data. This class also provides methods to manage image feature set which is a collection of individual feature data.
45 * The following example demonstrates how to use the %ImageFeatureManager class.
51 * #include <FGraphics.h>
55 * using namespace Tizen::Base;
56 * using namespace Tizen::Media;
57 * using namespace Tizen::Graphics;

78 * //Creates new feature sets
79 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image1.jpg");
80 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image2.jpg");
81 * imageFeatureManager.AddFeature("/opt/usr/media/Images/image3.jpg");

109 * This is the default constructor for this class. @n
110 * The object is not fully constructed after this constructor is called. @n
111 * For full construction, the Construct() method must be called right after calling this constructor.

119 * The resources are deallocated by this method.
120 * This destructor overrides Tizen::Base::Object::~Object().

127 * Initializes this instance of %ImageFeatureManager and create image feature set. @n

138 * For more information, see <a href="../org.tizen.gettingstarted/html/tizen_overview/application_filtering.htm">Application Filtering</a>.
