Hi! How many bands are actualy being considered in the Mean Shift segmentation process? According to the message by Jonathan Guinet I reproduce, only 1 band is used, but I'm not sure if this is the case for all the process or just for part of it. Thanks Agus
"""""""" Jonathan Guinet [email protected] Unsubscribe 10/21/13 to otb-users Hy Eleni you underline an interesting point in a previous message : " I notice that if I change the sequence of the bands ( ie from RGBLIDAR to LIDARRGB ) the output clustered image is different Is this reasonable? " this behavior is due to a processing optimization used by default when wrraping EDISON (the MED_SPEEDUP algorithm) : The bucket mode.explained in following reference : Mean Shift Segmentation Evaluation of Optimization Techniques Jens N. Kaftan and Andr`e A. Bell and Til Aach To reduce exploration space a 3D hypercube is used the bucket. this bucket is composed of spatial ranges : X,Y (the two first dimensions) and dynamic range (the third dimension) i.e. the first band of data. thus Only the first band of data is taken into consideration to reduce exploration Thus the sequence of band gives differents results.
