-
- \section intro Introduction
- The class Mosaic provides a simple interface to the panoramic mosaicing algorithm. The class allows passing in individual image frames to be stitched together, computes the alignment transformation between them, and then stitches and blends them together into a single panoramic output which can then be accessed as a single image. \
-
- \section usage Usage
- The class methods need to be called as outlined in the sample application which is created from the mosaic_main.cpp file in the directory src/mosaic/. A brief snapshot of the flow is given below:
-
- \code
- Mosaic mosaic;
- // Define blending types to use, and the frame dimensions
- int blendingType = Blend::BLEND_TYPE_CYLPAN;
- int stripType = Blend::STRIP_TYPE_THIN;
- int width = 640;
- int height = 480;
-
- while (<image frames are available>)
- {
- // Check for initialization and if not, initialize
- if (!mosaic.isInitialized())
- {
- // Initialize mosaic processing
- mosaic.initialize(blendingType, stripType, width, height, -1, false, 5.0f);
- }
-
- // Add to list of frames
- mosaic.addFrameRGB(imageRGB);
-
- // Free image
- ImageUtils::freeImage(imageRGB);
- }
-
- // Create the mosaic
- ret = mosaic.createMosaic();
-
- // Get back the result
- resultYVU = mosaic.getMosaic(mosaicWidth, mosaicHeight);
-
- printf("Got mosaic of size %d,%d\n", mosaicWidth, mosaicHeight);
-
- \endcode

-
- \section intro Introduction
-
- db_FrameToReferenceRegistration provides a simple interface to a set of sophisticated algorithms for stabilizing
- video sequences. As its name suggests, the class is used to compute parameters that will allow us to warp incoming video
- frames and register them with respect to a so-called <i>reference</i> frame. The reference frame is simply the first
- frame of a sequence; the registration process is that of estimating the parameters of a warp that can be applied to
- subsequent frames to make those frames align with the reference. A video made up of these warped frames will be more
- stable than the input video.
-
- For more technical information on the internal structure of the algorithms used within the db_FrameToRegistration class,
- please follow this <a href="../Sarnoff image registration.docx">link</a>.

- \section usage Usage
- In addition to the class constructor, there are two main functions of db_FrameToReferenceRegistration that are of
- interest to the programmer. db_FrameToReferenceRegistration::Init(...) is used to initialize the parameters of the
- registration algorithm. db_FrameToReferenceRegistration::AddFrame(...) is the method by which each new video frame
- is introduced to the registration algorithm, and produces the estimated registration warp parameters.
-
- The following example illustrates how the major methods of the class db_FrameToReferenceRegistration can be used together
- to calculate the registration parameters for an image sequence. In the example, the calls to the methods of
- db_FrameToReferenceRegistration match those found in the API, but supporting code should be considered pseudo-code.
- For a more complete example, please consult the source code for dbregtest.

- \code
- // feature-based image registration class:
- db_FrameToReferenceRegistration reg;
-
- // Image data
- const unsigned char * const * image_storage;
-
- // The 3x3 frame to reference registration parameters
- double frame_to_ref_homography[9];
-
- // a counter to count the number of frames processed.
- unsigned long frame_counter;
- // ...
-
- // main loop - keep going while there are images to process.
- while (ImagesAreAvailable)
- {
- // Call functions to place latest data into image_storage
- // ...
-
- // if the registration object is not yet initialized, then do so
- // The arguments to this function are explained in the accompanying
- // html API documentation
- if (!reg.Initialized())
- {
- reg.Init(w,h,motion_model_type,25,linear_polish,quarter_resolution,
- DB_POINT_STANDARDDEV,reference_update_period,
- do_motion_smoothing,motion_smoothing_gain,
- DB_DEFAULT_NR_SAMPLES,DB_DEFAULT_CHUNK_SIZE,
- nr_corners,max_disparity);
- }
-
- // Present the new image data to the registration algorithm,
- // with the result being stored in the frame_to_ref_homography
- // variable.
- reg.AddFrame(image_storage,frame_to_ref_homography);
-
- // frame_to_ref_homography now contains the stabilizing transform
- // use this to warp the latest image for display, etc.
-
- // if this is the first frame, we need to tell the registration
- // class to store the image as its reference. Otherwise, AddFrame
- // takes care of that.
- if (frame_counter == 0)
- {
- reg.UpdateReference(image_storage);
- }
-
- // increment the frame counter
- frame_counter++;

- It is SAFE to pass the same pointer as both the 'in' and 'out'

-# ===================================================================
-#h 1 Introduction
-
- This defines a motion model that can describe translation,
- affine, and projective projective 3d and 3d view transforms.
-
- The main structure VP_MOTION contains a 16 parameter array (That
- can be considered as elements of a 4x4 matrix) and a type field
- which can be one of VP_MOTION_NONE,VP_MOTION_TRANSLATION,
- VP_MOTION_AFFINE, VP_MOTION_PROJECTIVE,VP_MOTION_PROJ_3D or
- VP_MOTION_VIEW_3D. (These are defined using enums with gaps of 10
- so that subsets of these motions that are still consistant can be
- added in between. Motion models that are inconsistant with this set
- should be added at the end so the routines can hadle them
- independently.
-
- The transformation VP_MOTION_NONE,VP_MOTION_TRANSLATION,
- VP_MOTION_AFFINE, VP_MOTION_PROJECTIVE, VP_MOTION_PROJ_3D and
- VP_MOTION_SEMI_PROJ_3D would map a point P={x,y,z,w} to a new point
- P'={x',y',z',w'} using a motion model M such that P'= M.par * P.
- Where M.par is thought of as elements of a 4x4 matrix ordered row
- by row. The interpretation of all models except VP_MOTION_SEMI_PROJ_3D
- is taken to be mapping of a 3d point P"={x",y",z"} which is obtained
- from the normalization {x'/w',y'/w',z'/w'}. In the VP_MOTION_SEMI_PROJ_3D
- the mapping to a point P"={x",y",z"} is obtained from the normalization
- {x'/w',y'/w',z'}. All these motion models have the property that they
- can be inverted using 4x4 matrices. Except for the VP_MOTION_SEMI_PROJ_3D all
- other types can also be cascaded using 4x4 matrices.
-
- Specific macros and functions have been provided to handle 2d instances
- of these functions. As the parameter interpretations can change when adding
- new motion models it is HIGHLY RECOMMENDED that you use the macros MXX,MXY..
- ect. to interpret each motion component.
