It will be convenient to have some standard terminology by which we can discuss the effects a filter will have on an image, and to be able to choose the most appropriate filter for a given image[r]

This book is written at an introductory level in order to introduce undergraduate students to an exciting and practical field of DSP. We emphasize that this is not a textbook in the traditional sense but a com- panion book in which more attention is given to problem solving and hands-on experi[r]

These issues described above, along with some applications of wavelet analysis, are presented in the next section on implementation.
MATLAB Implementation
The construction of a filter bank in MATLAB can be achieved using either routines from the Signal Proce[r]

This review paper presents various techniques applied in satellite image enhancement and restoration. Our review findings shows that there exists lot of scope for performing satellite image enhancement and restoration using amalgamating soft computing techniques and conventional image processing.

In this method, cells show a complex behavior by interacting with each other. Image features involving edges, lines, borders and etc can be extracted in machine sight and image processing by using some mathematics operations sight and image processing by using mathematics operations such as edge det[r]

exists between two magnetic coils with the proper turns-ratio. Mutual induction is possible due to the rate at which the magnetic lines cut the wires of the transformer coils and the produced electromotive force that is capable of producing current in closed electric loops. This fu[r]

A variable name or function name can be any string of letters, digits, and underscores, provided it begins witha letter (punctuation marks are not al- lowed). MATLAB distinguishes between uppercase and lowercase letters. You should choose di[r]

Time–Frequency Analysis
BASIC APPROACHES
The spectral analysis techniques developed thus far represent powerful signal processing tools if one is not especially concerned with signal timing. Classical or modern spectral methods provide a complete and appropriate solution for wavefor[r]

The image produced by the range filter is shown in Figure 12.8, and a clear distinction in intensity level can now be seen between the three regions. This is also demonstrated in the histogram plots of Figure 12.9. The histogram of the original figure (upper plot) shows a sing[r]

r can have any value in the range [0 1].
3.2.4 Some Utility M-Functions for Intensity Transformations
In this section we develop two custom M-functions that incorporate various aspects of the intensity transformations introduced in the previous three sec- tions. We show the details
