%This function warps an image onto another within corner points using the
% homography matrix H
% Input Parameters : frame - image on which another image is to be warped
% imgToEmbed - image to be warped on frame
% H - Homography matrix
% cornerPts - corner points on frame in which warped
% image will be embed
% Output Parameters: warpedImg - final image after warping
Usage: warpedImg=imwarp( markerImage, imageToEmbed,H, vector1);

where vector1 is of meanpoints given in following format:
vector1= [ meanPoints(1,1) meanPoints(1,2);meanPoints(2,1) meanPoints(2,2); meanPoints(3,1) meanPoints(3,2); meanPoints(4,1) meanPoints(4,2)];

This function succesfully warps one image onto another. The only problem is that it takes 1.xx seconds in warping single image. I need some improvement in it to make it fast. Can anyone help me??
