Broadly similar results were obtained for conditional estimation, which may contain an optimistic bias, and for unconditional estimation, which largely avoids the bias.
Points generated by the above depth estimation step may contain outliers (points that do not belong to the object surface) that have to be removed.
The phase term,, may contain residual Doppler shift effect due to nonideal Doppler shift estimation and compensation.
Ideally, the more slices used, the more accurate the estimation of the object's volume, as they may contain more information.
A general issue in density estimation using constant intervals (categories) is that some intervals may contain very little data while others are well represented in the analyzed data set [ 40].
The disconnected components of the remaining spectrum are identified, some of which may contain a number of peaks due to peak overlapping or inaccuracy in the estimation of the noise level.
The reason is that this additional information may contain extreme values which may not be fully reliable and thus lead to worse estimation.
Butter may contain added colouring.
Metamorphic rocks also may contain separate assemblages.
Sputum discharge may contain flecks of blood.
