Compared to mask 1, mask 2 features more stringent requirements in terms of pass-band ripple and stop-band attenuation (needed to meet a target THD 0.2%) but allows for a larger transition band; indeed music signals rarely exceed the 17 kHz imposed by a pass-band of 0.4 and hence the pass-band 0.45 in mask 1 is often excessive.
ImageJ analysis was performed as follows: the image was converted into an 8-bit image, and filtered using the unsharp mask filter (radius 1, mask 0.60).
Thus, the initial goal is to create a binary (0, 1) mask allowing discrimination of the heart's tissue volume from the surrounding background volume and cavities as well as the extracellular cleft space and vessel lumens.
