Hi all,

I am struggeling with HolologousPointsExtraction for a multi-temporal set 
of RapidEye images (5m Resolution)

When I run the following code on the raw integere value image (u16bit) I 
get a large number of homolgous points (>10000).

otbcli_HomologousPointsExtraction -in1 "imageA_int.tif" -band1 4 -in2 
"imageB_int.tif" -band2 4 -backmatching 1 -precision 10 -mfilter 1 -threshold 
0.6 -mode full -2wgs84 1 -elev.geoid dtm_utm32_wgs84.tif -out tie_points.txt 
-outvector tie_points.shp


However, when I convert the images to floating point values (Float 32bit)  
when calulating  TOA I don't get any match points for exactly the same 
images

otbcli_HomologousPointsExtraction -in1 "imageA_float.tif" -band1 4 -in2 
"imageB_float.tif" -band2 4 -backmatching 1 -precision 10 -mfilter 1 -threshold 
0.6 -mode full -2wgs84 1 -elev.geoid dtm_utm32_wgs84.tif -out tie_points.txt 
-outvector tie_points.shp



Any suggestions?
