Jialei Chen, Daisuke Deguchi, Chenkai Zhang, Xu Zheng, Hiroshi Murase

Abstract: Highlights•Frozen prototypes outperform the learning-based classifier in semantic segmentation.•We propose a new loss function to further shape the feature space for frozen prototypes.•Discriminatively initialized prototypes contain much potential for future tasks.
