Application of Wavelet Vector Multi-resolution Technique to Piv Measurements
A wavelet-based vector multi-resolution technique was applied to analyze the three-dimensional measurement results of a high-resolution stereoscopic PIV system in this paper. The instantaneous threedimensional flow structures in the near field of lobed jet mixing flow were successfully decomposed into largeand small-scale structures based on the wavelet vector multi-resolution analysis. It is f...
متن کاملevaluation of sadr eminence in safavid period
چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...
15 صفحه اول2D Image Compression Using Wavelet Compression Technique by Analysis
Compressing an image is significantly different than compressing raw binary data. Of course, general purpose compression programs can be used to compress images, but the result is less than optimal. The compression is achieved by many algorithms like Haar, EZW, JPEG2000 and SPIHT [4] and we can get some good results but more efficient algorithm is required which is necessary to improve the PSNR...
متن کاملInterframe wavelet coding - motion picture representation for universal scalability
Scalability at the bitstream level is an important feature for encoded video that is to be transmitted and stored with a variety of target rates or to be replayed on devices with different capabilities and resolutions. This is attractive for digital cinema applications, where the same encoded source representation could seamlessly be used for purposes of archival and various distribution channe...
متن کاملEvaluation of Wavelet Filters for Image Compression
The aim of this paper to characterize a larger set of wavelet functions for implementation in a still image compression system using SPIHT algorithm. This paper discusses important features of wavelet functions and filters used in sub band coding to convert image into wavelet coefficients in MATLAB. Image quality is measured objectively using peak signal to noise ratio (PSNR) and its variation ...
