Sparisty Performance Of Endoscopic Ultrasound Signal Under Different Sparse Transforms

This paper introduced the compressed sensing (CS) technique into endoscopic ultrasound (EUS). An In-vitro tissue experiment of swine digestive was designed to obtain high-quality EUS signals. Two kinds of EUS signals were obtained through traditional sinusoidal excitation and chirp coded excitation. Four types of sparse bases - discrete cosine transform (DCT), discrete wavelet transform (DWT), Had...
