Maps texture in I according to rowDst and colDst. I has (nrows*ncols) coordinates. Each coordinate has an associated intensity value. A transformation on I can be defined by giving the destination (r',c') of the intensity associated with coordinate (r,c) in I -- ie I(r,c). Applying the transformation, we ask what intensity is associated with a coordinate (r0',c0') by interpolating between the intensities at the closest coordinates (r',c'). In the function below specify the destination of (r,c) by (rowDst(r,c), colDst(r,c)). If the inverse mapping is also available -- ie if we can go from the coordinates in the destination to the coordinates in the source, then a much more efficient procedure can be used to textureMap that involves interp2 instead of griddata. See imtransform2 for example usage in this case. The bounding box of the image is set by the BBOX argument, a string that can be 'loose' (default) or 'crop'. When BBOX is 'loose', IR includes the whole transformed image, which generally is larger than I. When BBOX is 'crop' IR is cropped to include only the central portion of the transformed image and is the same size as I. USAGE IR = textureMap( I, rowDst, colDst, [bbox], [holeVal] ) INPUTS I - 2D input image rowDst - rowDst(i,j) is row loc where I(i,j) gets mapped to colDst - colDst(i,j) is col loc where I(i,j) gets mapped to bbox - ['loose'] see above for meaning of bbox 'loose' or 'crop' holeVal - [0] Value of the empty warps OUTPUTS IR - result of texture mapping boundaryX - returns the smallest/biggest x coordinate of the output boundaryY - returns the smallest/biggest y coordinate of the output EXAMPLE See also IMTRANSFORM2 Piotr's Image&Video Toolbox Version 2.50 Copyright 2010 Piotr Dollar.
