+/*! \mainpage Mosaic
+
+    \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);
