Figure 15From: Balloon energy based on parametric active contour and directional Walsh–Hadamard transform and its application in tracking of texture object in texture backgroundEvaluating effect of noise on the proposed method for tracking texture object in texture background for different SNR. SNR = 14.47 dB (1strow), 7.48 dB (2ndrow), 4.47 dB (3rdrow), 2.70 dB (4throw), 1.46 dB (5throw), and 0.49 dB (6throw) for frames from left to right:1, 20, 30,41.Back to article page
