topic PyramidLayerUp function problem in Intel® Integrated Performance Primitives https://community.intel.com/t5/Intel-Integrated-Performance/PyramidLayerUp-function-problem/m-p/898034#M12373 Hi,<BR /><BR />I am trying to use the Universal pyramid functions to decompose and reconstruct a Gaussian as well as Laplacian pyramids (for image contrast/sharpness enhancement purposes). Before I actually implement the Laplacian pyramid, I wanted to decompose and reconstruct a Gaussian pyramid and test if the image reconstructs correctly.<BR /><BR />If the ROI provided to the pyramid structure is a non-square rectangle then the pyramid decomposition gives me the correct images for all levels I use, however, the reconstruction loop only reconstructs part of the image. For a square ROI the reconstruction works fine. Is this a limitation of the PyramidLayerUp function - does it only work for square ROIs?<BR /><BR />Any thoughts/suggestions will be very appreciated. Thank you,<BR /><BR />Mittal<BR /><BR /> Mon, 29 Oct 2007 20:59:42 GMT bhatt1 2007-10-29T20:59:42Z PyramidLayerUp function problem https://community.intel.com/t5/Intel-Integrated-Performance/PyramidLayerUp-function-problem/m-p/898034#M12373 Hi,<BR /><BR />I am trying to use the Universal pyramid functions to decompose and reconstruct a Gaussian as well as Laplacian pyramids (for image contrast/sharpness enhancement purposes).
