Fast Template Matching by Subsampled Circulant Matrix
Sung-Hsien Hsieh, Chun-Shien Lu, and Soo-Chang Pei
Template matching is widely used for many applications in image and signal processing and usually is time-critical. Traditional methods usually focus on how to reduce the search lo…
Fast Greedy Approaches for Compressive Sensing of Large-Scale Signals
Sung-Hsien Hsieh, Chun-Shien Lu, Soo-Chang Pei
Cost-efficient compressive sensing is challenging when facing large-scale data, {\em i.e.}, data with large sizes. Conventional compressive sensing methods for large-scale data wil…
Sparse Fast Fourier Transform for Exactly and Generally K-Sparse Signals by Downsampling and Sparse Recovery
Sung-Hsien Hsieh, Chun-Shien Lu, Soo-Chang Pei
Fast Fourier Transform (FFT) is one of the most important tools in digital signal processing. FFT costs O(N \log N) for transforming a signal of length N. Recently, Sparse Fourier…
