Image super resolution is a research hot spot in the field of low level vision. The existing methods based on convolutional neural network do not optimize the image super resolution as a regression problem. These methods are weak in learning ability and require too much time in training step, also leaving room for improvement in the quality of image reconstruction. To solve above mentioned problems, this article proposes a method based on deep deconvolution neural network, which first upsamples low resolution image by deconvolution layer, and then uses deep mapping to eliminate the noise and artifacts caused by deconvolution layer. The residual learning reduces the network complexity and avoids the network degradation caused by the depth network. In Set 5, Set 14 and other datasets, the presented method performs better than FSRCNN in PSNR, SSIM, IFC and visual.
