Abstract EN
We propose a new computational intelligence method using wavelet optical flow and hybrid linear-nonlinear classifier for object detection.
With the existing optical flow methods, it is difficult to accurately estimate moving objects with diverse speeds.
We propose a wavelet-based optical flow method, which uses wavelet decomposition in optical flow motion estimation.
The algorithm can accurately detect moving objects with variable speeds in a scene.
In addition, we use the hybrid linear-nonlinear classifier (HLNLC) to classify moving objects and static background.
HLNLC transforms a nonoptimal scalar variable into its likelihood ratio and uses a scalar quantity as the decision variable.
This approach is appropriate for the classification of optical flow feature vectors with unequal variance matrices.
The experimental results confirm that our proposed object detection method has an improved accuracy and computation efficiency over other state-of-the-art methods.
