MuRNet: A deep recursive network for super resolution of bicubically interpolated images

作者:

Highlights:

• A new recursive block for the problem of single image super resolution that generates a very rich set of features resulting from different spatial ranges and different resolution levels is proposed in order to provide a state-of-the-art performance.

• Through a careful choice of the number of filters, the total number of parameters of the recursive block, and hence, that of the network is kept low.

• The recursion process provides the network with a sufficient effective depth and yet the number of operations is kept low in view of the small number of parameters used by the recursive block.
