works great. color map could be controlled, zoom could be added etc

08 Apr 2013 OpenSURF (including Image Warp) SURF (Speeded Up Robust Features) image feature point detection / matching, as in SIFT Author: Dirk-Jan Kroon

I found a solution. I just used MATLABs tranformation functions from Image Processing Toolbox

my_M = cp2tform(Pos1(:,1:2) ,Pos2(:,1:2),'affine');
my_warped = imtransform(I1,my_M);

08 Apr 2013 OpenSURF (including Image Warp) SURF (Speeded Up Robust Features) image feature point detection / matching, as in SIFT Author: Dirk-Jan Kroon

Hi,

I tried to run example 3 with a re-sized source image (scaled 0.5 time).
After fixing some of the plotting issues, openSURF seems to find correct features, but the warped image is "cropped" at the top-left corner (but upright).
I then un-commented the following lines in affine_warp.m:
mean= size(Iin)/2;
xd=x-mean(1);
yd=y-mean(2);

now the warped image is cropped around the center of the image (and upright).

any hints?
