_D_e_s_c_r_i_p_t_i_o_n:

     This function provides various ways to threshold a 'imwdc' class
     object.

_U_s_a_g_e:

     threshold.imwdc(imwdc, verbose=FALSE, ...)

_A_r_g_u_m_e_n_t_s:

   imwdc: The two-dimensional compressed wavelet decomposition object
          that you wish to threshold.

 verbose: if TRUE then the function prints out informative messages as
          it progresses.

     ...: other arguments passed to the 'threshold.imwd' function to
          control the thresholding characteristics such as policy, type
          of thresholding etc.

_D_e_t_a_i_l_s:

     This function performs exactly the same function as
     'threshold.imwd' except is accepts objects of class 'imwdc' rather
     than imwd. Indeed, this function physically calls the
     'threshold.imwd' function after using the 'uncompress' function to
     convert the input 'imwdc' object into a 'imwd' object.

_V_a_l_u_e:

     An object of class 'imwdc' if the compression option is supplied
     and set to TRUE, otherwise a 'imwd' object is returned. In either
     case the returned object contains the thresholded coefficients.
     Note that if the 'return.threshold' option is set to TRUE then the
     threshold values will be returned rather than the thresholded
     object.
