Image processing is a way to convert an image to a digital aspect and perform certain functions on it, in order to get an enhanced image or extract other useful information from it. It is a type of signal time when the input is an image, such as a video frame or image and output ca...
1.) wavelet frames can be much more directionally selective for image processing than orthogonal or biorthogonal wavelets. 2.) wavelet frames can be shift invariant whereas an orthogonal or biorthogonal wavelet transform is not shift invariant ...
aWavelet analysis has becomed an indispensable way in image processing. In this project, image compression using simple haar wavelet transform are programmed by matlab. The goal of this paper is to get how much the original images are compressed, how those compressed signal look alike and to im...
Now, we need to separate the speech signal into short-time frames. To do that a Discrete Fourier Transform (DFT) on each frame (especially a Short-Time Fourier Transform) is applied and calculate the energy or power spectrum. Hence, we get an approximation of the frequency spectrum of the ...
Different types of wavelets have been used as tools to solve problems in signal analysis, image analysis, medical diagnostics, boundary - value problems, geophysical signal processing, statistical analysis, pattern recognition, and many others. A reason for the popularity of wavelets is their ...

Automatic facial expression recognition is a big challenge in human–computer interaction. Analyzing the changes in the face during a facial expression can be used for this purpose. In this paper, these changes are extracted as a number of motion vectors. These motion vectors are extracted using ...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
What is in store in the July-August 2019 issue of IETE Technical Review?There are interesting papers in this issue covering topics ranging from sensors, communication engineering, IoT, Image processing and RADARs. The papers are written in a lucid language. We hope that the papers presented in...
Machine learning plays a vital role in today’s world due to its ability to analyze vast amounts of data, recognize patterns, and make accurate predictions or decisions. Here are some key reasons why machine learning is important: 1. Automation and Efficiency:By automating tasks that traditionall...
