 [Vxl-users] Making Correspondences: Cross-correlation computation with RGB format ! From: Xiaowei Li - 2004-10-14 15:40:08 ```Hi,Everyone=A3=A1 =09For making putative correspondences in RANSAC, the= cross-correlation computation is necessary. =09I found only in "core/vil1/vil1_memory_image_window.cxx" there= is a cross correlation computation member function. But= unfortunately, the function "double= vil1_memory_image_window::normalised_cross_correlation(const= vil1_memory_image_of& image2,int centre2_x, int= centre2_y)" seems to only support gray images becauseof= "vcl_byte", and in my experiment, the images are all of RGB= channels. =09How can I solve this,Can anyone help me ? =09Thanks.;) Best Regards, =09=09=09=09 Shawrie Lee(Xiaowei Li) ```
