We generated and analyzed feature sets that might be obtained from ship contour images. By varying the amount of fluctuation in the data we were able to describe mechanisms that affect the ability to distinguish targets that are similar (from the same class) or different (from a different ...
This paper adopts a method to determine and adjust two key parameters of Gaus- sian function (center and width). The method adopted in this paper is to determine the center of Gaussian func- tion by using the FCM algorithm, and to optimize its width by using PSO algorithm when the center...
The core idea of our algorithm is to encode and decode on different combinations of time–frequency signals to achieve multimodal alignment. Figure 1 depicts the time signal waveform, the frequency signal waveform, and the key region of ten categories of wvd. Essentially, the hardware difference ...
The key novelty of this method is that, by means of selecting appropriate 2D-intrinsic modes, it is not only used in feature extraction, but also for 2D signal/image denoising and sharpening, which lays a foundation for further feature extraction by using CDNNs. The experimental results show ...
