Fig. 1. Setup of LFSI.
Fig. 2. Simulation results. (a) ‘HNU’ binary image. (b) Original edge image of (a). (c)–(e) The results of edge detection based on Scheme I, Scheme II, and LFSI, respectively.
Fig. 3. Simulation results after adding noise. (a)–(c) Results of edge detection based on Scheme I, Scheme II, and LFSI. (d) Morphological processing results of (c). First row: adding SNR = 10 dB detection noise and no light source noise; second row: adding SNR = 10 dB light source noise and no detection noise; third row: adding SNR = 10 dB detection noise and light source noise.
Fig. 4. Simulation results after adding noise. (a1), (a2) Original image and edge image of ‘windmill’ grayscale image. (b)–(d) Results of edge detection based on Scheme I, Scheme II, and LFSI, respectively. (e) Morphological processing results of (d). First row: adding SNR = 10 dB detection noise and no light source noise; second row: adding SNR = 10 dB light source noise and no detection noise; third row: adding SNR = 10 dB detection noise and light source noise.
