thresholding: A process of creating a black-and-white image out of a grayscale image consisting of setting exactly those pixels to white whose value is above a given threshold, setting the other pixels to black.
Society is increasingly relying on computers to extract meaning and information from digital images. Partial differential equations are a popular and well-studied tool for computer vision applications, but the anti-geometric heat flow has been overlooked. The goal of this thesis is to demonstrate ...
The three window functions are defined by(13)WEXP(t)=A(e−αt−e−βt);(14)WGAUSS(t)=1σ2πe−t2/2σ2;(15)WRECT(t)=1,t0≤t≤t10,otherwise;where A, α and β have the same meaning as in Eq. (11), yet with different values. σ represents the standard deviation of...
Performing correlation analysis for all possible pairs of brain regions results in a functional connectivity matrix for each of the individual subjects, with the obtained case and control matrices often “thresholded”, meaning the selection of those connections that reach a certain absolute or relative...
in-continuity nerve roots as avulsed1, meaning that many surgeons still undertake exploratory surgery. This shortfall in conventional imaging might be improved by diffusion tensor imaging (DTI), which is sensitive to changes in the microstructure of peripheral nerves (e.g. myelination, axon ...
Our first\ncontribution is a theoretical analysis of the normalized Iterative Hard\nThresholding (IHT) algorithm when all input data, meaning both the measurement\nmatrix and the observation vector are quantized aggressively. We present a\nvariant of low precision normalized {IHT} that, under mild...
All curves are clearly distinct, meaning a significant effect of the spray pressure on volumetric diameters. Figure 4. Cumulative volume curves as affected by spraying pressure. 3.2. Relationship between Threshold Values and Gray Levels Figure 5 shows the relationship between the average gray level ...

For binary change detection, C is set to 2, meaning the initial threshold 𝜏0τ0 is set to 0.5.After adopting the adaptive threshold, the confidence mask map corresponding to the high-quality and quantity of pseudo-labels obtained through our screening process can be redefined as 𝐦𝐭∈...
This would help us to evaluate the potential of the whole process and to see if there is any meaning in continuing with it. Of course, based on our results in [2,20,21], we believed that most probably we would obtain some pretty good results. Thus, we trained an ANFIS with 252 ...
