The imaging system is taken as a stable  linear  time-invariant  and causal filter  and its transfer function is measured through the pseudo-random binary sequence impulse responses identification. A digital mirror device (DMD) light projector is developed as the target generator  and wavelet thresholding is used to denoise the captured image. Pre-filtering spectral estimation algorithm with adaptive parameter selection is also proposed for the identification process  overcoming the challenge brought by the size limit derived from the optical isoplantic region. Simulations and experiments are presented to show the effectiveness of the proposed method.0-64. 2010 IEEE.   Modulation transfer function measurement of sampled imaging systems in field test (EI CONFERENCE) 会议论文 5th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, April 26, 2010 - April 29, 2010, Dalian, China Yang L.; Sun Q.; Wang J.; Zhang J. 收藏  |  浏览/下载：16/0  |  提交时间：2013/03/25 A digital mirror device (DMD) based light projector was developed as the target generator in modulation transfer function (MTF) measurement. In order to overcome the sampling-scene phase effect in MTF measurement of sampled imaging systems  a method using random targets is introduced to yield a phase-averaged MTF. The main potential problem of implementing this method is the fact that the stationary assumption of the random targets may be vitiated in practical measurement  especially in field test due to the ill condition. We provide an efficient model-independent way of analyzing and isolating the spectral contents arising from these additional contributions to MTF measurement. Algorithms with adaptive parameter selection were also developed for spectral estimation of the test image in order to overcome the challenge brought by the size limit of the test matrices for one certain field of view derived from the isoplantic region. The MTF measurement of a CCD video imager is used to demonstrate the measurement technique and illustrate the benefits over other methods. In order to validate the results  comparisons have been made between MTF measurements of imager implemented using this method and bar target direct measurements. 2010 Copyright SPIE - The International Society for Optical Engineering.   Improved Mean Shift Segmentation Scheme For Medical Ultrasound Images 会议论文 4th International Conference on Bioinformatics and Biomedical Engineering (iCBBE), JUN 18-20, 2010 作者:  Bai, Peirui;  Fu, Caihong;  Cao, Maoyong;  Han, Yan 收藏  |  浏览/下载：1/0  |  提交时间：2019/12/31 Medical ultrasound image segmentation  Mean shift  adaptive gray domain  bandwidth selection  threshold-based region mergence   Dynamic autofocusing region selection based on improved PSO 期刊论文 Proceedings - 2010 3rd International Congress on Image and Signal Processing, CISP 2010, 2010, 卷号: 6, 页码: 2760-2764 作者:  Wang, Yanfang;  Jiang, Wei;  Zheng, Yuanyuan 收藏  |  浏览/下载：2/0  |  提交时间：2019/12/26 Adaptive autofocusing  Dynamic focus-region selection  Image processing  PSO
