摘要：Wavelet theory is one the greatest achievement of last decade. Wavelet theory has gained popularity in solving difficult problems in mathematics, engineering etc. It can be employed in lots of fields and applications, such as signal processing, image analysis, communication systems, time frequency analysis, image compression, smoothing and image denoising , pattern recognition, finger print verification, DNA analysis, computer graphics etc. The results produced by wavelet based analysis have really astonished the modern research communities in various fields. Wavelet based analysis is still an active research area due to its tremendous applications. This paper provides basic concepts of wavelet transforms and brief idea of recent published works dealing with applications of wavelet theories.
