Abstract

Over the years, many methods have emerged to solve the super-resolution problem of light field images, and among them, those methods based on deep learning are noted quite attractive recently. Although the features extracted from epipolar domain for the super-resolution of light field images are actively investigated due to their potential capability of well capturing the relationship between spatial and angular domains, we note that spatial features are still the most important foundation in feature extraction. In this paper, we design a network, named as LFSelectSR, employing multiple convolutional kernels to fully extract spatial features and introduce a dynamic selection mechanism that can extract the most valuable spatial features. By training and testing the network using well-known datasets, we demonstrate its excellent performance of achieving the level of state-of-the-arts under certain conditions.
