Zynq-Based Reconfigurable System for Real-Time Edge Detection of Noisy Video Sequences

Figure 8

Comparison of edge detection results for the noisy video sequences.

(a) Noisy video #1 (salt-and-pepper noise density: 20%)

(b) Noisy video #2 (salt-and-pepper noise density: 20%)

(c) Output of Sobel filter: original video #1

(d) Output of Sobel filter: original video #2

(e) Output of Sobel filter (noisy video #1)

(f) Output of Sobel filter (noisy video #2)

(g) Output of Median + Sobel filter (noisy video #1)

(h) Output of Median + Sobel filter (noisy video #2)
