This paper proposed video stabilization techniques using undesired motion detection and alpha-trimming mean filter. The proposed method consists of detecting undesired motions step and filtering the undesired motions step. The limitation on undesired motions is defined, using the local motion information. The alpha-trimming mean filter's alpha is controlled based on this limitation, so that regenerated...
By analyzing the theory of functional link artificial neural network (FLANN) structure based on filtered-s least mean square (FSLMS) algorithm which is usually used in the nonlinear active noise control (NANC) system, it can be found that the controller coefficients of nonlinear parts are multiple related, this problem causes much unbalance to calculate these coefficients and restraints the performance...
Conventional audio-integrated feedback active noise control (ANC) systems use single rate to process low rate noise signal and high rate audio signal, which degrades the performances of both ANC and audio systems. This paper presents multirate audio-integrated feedback ANC system to admit the different sampling frequency in both ANC and audio system based on interpolation and decimation techniques...
To comprise the advantages of both the spatial domain and transform domain methods, this paper presents a novel hybrid algorithm for multi-focus images fusion, which reduces the error rate of sub-band coefficients selection in the transform domain and reduce the artificial discontinuities created in the spatial domain algorithms. In this method, wavelet transforms are firstly performed on each input...
In this paper, we propose an online secondary-path-modeling ANC system with simultaneous perturbation (SP) method. This system updates the noise control filter by the FXNLMS algorithm, which has fast convergence in the case when the modeling error of the secondary path model is small. If the secondary path changes, the noise control filter is updated by the SP method, which does not require the secondary...
