(E): SG filter 𝑘4=5k4=5, 𝑚4=51m4=51. The dotted black line is the original peak and solid red line is the smoothed peak. Figure 2. Smoothing performance of Adaptive Savitzky–Golay. (A): Original peak corrupted with noise; (B): SG filter 𝑘1=2k1=2, 𝑚1=253m1=253...
With the development of computer vision, Deep Neural Network has shown outstanding performance in image recognition. According to the time correlation embedded in the gas sensor data, the SG algorithm in the previous section is used to smooth and filter the time series data into a two-dimensional...
