Function Documentation

void env_motion_channel_input_and_consume_pyr ( struct env_motion_channel chan,
const char *  tagName,
const struct env_params envp,
const struct env_math imath,
const struct env_dims  inputdims,
struct env_pyr lowpass5,
env_chan_status_func *  status_func,
void *  status_userdata,
struct env_image result 
)

env_motion_channel only requires luminosity input

for efficiency, the motion channel takes ownership of the lowpass5 pyramid (rather than needing to make a copy of it), so that after this function the lowpass5 argument will point to an empty pyramid
