In order to alleviate the inherent trade-off relation between spatial and angular resolutions of light field (LF) images, many experiments have been carried out to enhance the angular resolution of LFs by creating novel views. In this paper, we investigate a method to enhance the angular resolution of LF image by first grouping the pixels within and across the multiple views into LF superpixels using existing LF segmentation method, then generating novel views by shifting and overlaying the layers containing the LF superpixels having similar per-view disparity values. Experimental results with synthetic and real-scene datasets show that our method achieves good quality of reconstruction.
