void strk_region_info::init (   ) 
 

void strk_region_info_params::InitParams (  float  sigma,
bool  gradient_info,
bool  color_info,
float  min_gradient,
float  parzen_sigma,
bool  verbose,
bool  debug
)  [protected, inherited]

bool strk_region_info::map_i_to_0 (  vgl_h_matrix_2d< double > &  H  )  [protected]
 

map the intensities from image i to the coordinate frame of image 0.

assumes a homography between the images is defined by a face with 4 vertices

Definition at line 234 of file strk_region_info.cxx.

bool strk_region_info_params::SanityCheck (   )  [inherited]
