In this paper, we introduce a new framework for statistical signal processing based on wavelet - domain hidden markov models ( hmms ) that concisely models the statistical dependencies and nongaussian statistics encountered in real - world signals, since the wavelet transform can decorrelate image data by reducing the number of states of wavelet coefficients, thus making wavelet - domain hmms manipulable and usefu l for statistical image modeling
本文介紹了一種統計信號處理的框架模型,這種模型是基於小波域的隱馬爾可夫模型,它可以簡潔地對實際生活中遇到的信號的統計相關性和非高斯統計進行建模。因為小波變換可以通過減少小波系數的狀態數量來去除圖像數據的相關性,因此小波域的隱馬爾可夫模型對于統計圖像建模是可以掌控的和有用的。The kalman filter theory is introduced and the dynamic error vector equation of the initial alignment is derived at the first. using velocity error as exterior value of observation, maneuverable characteristic that is influenced with system ' s observability and its degree is studied at length by do amount of simulations and experiences. choosing output error of accelerometers and angle error of attitude as observation respectively and system observation model is derived, which is based on analyzing kalman filter theory
