Flame Image of Pint-Sized Power Plant's Boiler Denoising Using Wavelet-Domain HMT Models

Wavelet-domain hidden Markov Tree (HMT) was recently pro-posed and often applied to image processing. In this paper, HMT is app-lied to denoise the flame image of boiler and has gotten a good result. Having compared with other denoise methods such as wavelet, Wiener filter and median filter. HMT can get better denoise result and the content of flame image edges can be kept better. With the development of HMT research, it will be extended to the fields of signal processing, detection of edge and classification.
