NAME

lqr_carver_bias_set_energy_function_builtin - set a builtin energy function for a LqrCarver object  

SYNOPSIS

#include <lqr.h>
LqrRetVal lqr_carver_set_energy_function_builtin(LqrCarver* carver, LqrEnergyFuncBuiltinType ef_ind);
 

DESCRIPTION

The function lqr_carver_set_energy_function_builtin allows to pick a builtin energy function for the LqrCarver object pointed to by carver.

The possible values for ef_ind are:

LQR_EF_GRAD_XABS

absolute value of the brightness gradient in the direction of the rescaling (this is the default)

LQR_EF_GRAD_SUMABS

sum of absolute values of the brightness gradients in both directions

LQR_EF_GRAD_NORM

norm of the brightness gradient

LQR_EF_LUMA_GRAD_XABS

absolute value of the luma gradient in the direction of the rescaling

LQR_EF_LUMA_GRAD_SUMABS

sum of absolute values of the luma gradients in both directions

LQR_EF_LUMA_GRAD_NORM

norm of the luma gradient

LQR_EF_NULL

null

All of the above gradient functions have a radius of 1 pixel.  

RETURN VALUE

The return value follows the Liquid Rescale library signalling system.
