The signal waveform is constructed as in Example 6.1. A time vector,ti,is generated that will be used to produce the positive half of the wavelet. Thisvector is initially scaled so that the mother wavelet (a = 1) will be ± 10 seclong. With each iteration, the value of a is adjusted (128 different va[r]

temperature transducers utilize this feature. Other examples include the straingage, which measures mechanical deformation using the small change in resis-tance that occurs when the sensing material is stretched.Many critical problems in medical diagnosis await the development ofnew approache[r]

Note that the presented scheme builds the descriptionsin the temporal domain of the video, but it can be combinedwith structures introducing the redundancy in the spatial do-main, for which many more solutions have been proposed inthe literature. The increased flexibility thus achieved may beexploite[r]

The first strategy is to use a very small PSF, often only 3×3 pixels. This is carried out by looping through each sample in the output image, using optimized code to multiply and accumulate the corresponding nine pixels from the input image. A surprising amount of processin[r]
