In order to further explore the possibility of applying super-resolution methods on computing and storage resource-constrained devices, this study focuses on the application of deep convolutional neural network technology in single-image super-resolution, especially how to improve the performance of the network without significantly increasing the network size. In this paper, a novel lightweight single image super resolution (SISR) method via progressive multi-path feature fusion and attention mechanism (MPFFA) is proposed. MPFFA includes a multi-path FPF module, which can progressively guide and calibrate the learning of the following features through multiple paths. MPFFA also includes a multi-path feature attention mechanism (FAM), which can improve the utilization rate of feature information and the ability of feature expression by splicing multi-path features with weights. The experimental result shows that MPFFA significantly outperforms other representative methods, thus achieves a better balance between model complexity and performance. The proposed model can be better applied to computing and resource-constrained devices.
