Deblurring of a microscopy cell image. (a) is the actual cell image. (b) is the blurred image. (c)–(f) show the deblurred images using TV, HDTV2, TGV, and HS1 schemes, respectively. The results show that TV brings in patchy artifacts, while higher degree TV schemes preserve more details. HDTV2, TGV, and HS1 methods provide almost similar results both visually and in SNR, with a 0.5 dB SNR improvement over standard TV.
