ESRGAN: Enhanced Super-Resolution Generative Adversarial Networks. We extend ESRGAN for scale x2 and scale x1. Note: This is one option for scale 1, scale 2 in RRDBNet. We first employ the pixel-unshuffle (an inverse operation of pixelshuffle to reduce the spatial size and enlarge the channel size before feeding inputs into the main ESRGAN architecture. Args: num_in_ch (int): Channel number of inputs. num_out_ch (int): Channel number of outputs. num_feat (int): Channel number of intermediate features. Default: 64 num_block (int): Block number in the trunk network. Defaults: 23 num_grow_ch (int): Channels for each growth. Default: 32. r r ér csÔtt|ƒ ¡||_|dkr|d}n|dkr|d}t ||ddd¡|_tt|||d|_ t ||ddd¡|_ t ||ddd¡|_ t ||ddd¡|_ t ||ddd¡|_ t ||ddd¡|_tjddd |_dS) Nr r rér )rrrTr)rr2rÚscalerrÚ conv_firstrr-ÚbodyÚ conv_bodyÚconv_up1Úconv_up2Úconv_hrÚ conv_lastrr)rZ num_in_chZ num_out_chr5rZ num_blockrrr r!rZs  ÿzRRDBNet.__init__c Cs¨|jdkr t|dd}n|jdkrt|dd}n|}| |¡}| | |¡¡}||}| | tj|ddd¡¡}| |  tj|ddd¡¡}|  | |  |¡¡¡}|S)Nr )r5rr Únearest)Z scale_factorÚmode) r5rr6r8r7rr9ÚFZ interpolater:r<r;)rr$ZfeatZ body_featr1r r r!r&ss   ÿÿzRRDBNet.forward)r r r3r r'r r rr!r2Fsúr2) r"rZtorch.nnrr?Z arch_utilrrrÚModulerr-r2r r r r!Ús  $
