摘要:S-transform is an effective time-frequency analysis technique which can provide simultaneous time and frequency distribution information similar to the wavelet transform (WT); and discrete orthonormal S-transform (DOST) can reduce the redundancy of S-transform further. So we propose a medical image denoising and compressing method using DOST. We first introduce the ideas of WT based image denoising into DOST domain and propose the thresholding-based image denoising using DOST; and then we use Huffman coding in DOST domain to compress the images. Applications for fluoroscopic image and computed tomography (CT) image illustrate the good performance of the proposed method and show its high potential for diagnostic imaging.
