摘要： Based on wavelet multi-resolution analysis and mean-shift Unsupervised texture segmentation method and the mean shift clustering based on wavelet feature completely unsupervised adaptive multi-scale segmentation and neither the need for training is not necessary to split the categorya priori knowledge of the number, etc. the method according to the strategy in scale between the transmission of information, adaptive to different regions of the image to determine the appropriate split of the scale, texture inner region using the coarse scale features at the junction between the different texture to use smaller scale features to ensure regional consistency to more accurately locate the image edge contrast experimental results show that the method has good performance in the synthetic textures and real texture image, multi-scale segmentation process is similar to human visual system, perception, and advantages compared to the traditional supervised segmentation method. ©2012 Praise Worthy Prize S.r.l. - All rights reserved.

关键词： Fourier series;SPWM;harmonic wave;analyze

摘要： A mathematical model for the output waveform of SPWM VSI (voltage source inverter) is created specific to the harmonic problem of SPWM voltage source inverter. Through theoretical analysis and calculation, we can get the distribution regularity of the output harmonic wave in the process of frequency conversion and voltage transformation. Utilizing the matlab to verify the simulation, we can get such results like "frequency conversion will lead to the shift of the harmonic wave's distribution center", "voltage transformation will cause the valuable change of the harmonic wave and the valuable change direction of harmonic wave is opposite to that of the fundamental wave". All of these will have significant guide meaning to the application of SPWM.
