A New Method for Signal and Image Analysis: The Square Wave Method
This is an incremental method for signal and image processing researchers, as it builds on existing frequency domain techniques.
The paper tackles signal and image analysis by introducing the Square Wave Method (SWM) and Square Wave Transform (SWT) in the frequency domain, applying it to an electromyographic recording and the Lenna image, but no concrete results or numbers are provided.
A brief review is provided of the use of the Square Wave Method (SWM) in the field of signal and image analysis and it is specified how results thus obtained are expressed using the Square Wave Transform (SWT), in the frequency domain. To illustrate the new approach introduced in this field, the results of two cases are analyzed: a) a sequence of samples (that is, measured values) of an electromyographic recording; and b) the classic image of Lenna.
