We describe a simple way to retrieve images from a database. During training a wavelet-based description of the histogram of circular window of each image is first obtained using Daubechies 4- wavelet transformation. Resulting coefficients are used to train a neural network (NN). For image retrieval an image is presented to the system. The system responds with the most similar images. Results are...
We face the problem of retrieving images from a database. During training a wavelet-based description of each image is first obtained using a Daubechies 4-wavelet transformation. Resulting coefficients are used to train a neural network (NN). During retrieval, a given image is presented to the already trained NN. The system responds with the most similar images. Three different ways to obtain the...
This paper contains a synthesis to model an electromagnetic levitation system using a direct evaluation method of electromagnetic and electromotive forces, taking the Maxwell equations that relate electric and magnetic fields. The aim of this work is to contribute to researches focused on developing and optimising mechanisms to provide solutions for applications where mechanical friction must be reduced...
