At first, illumination equalization is used to the original RGB image to reduce the interference resulting from uneven illumination.
Several works based on sub-channel equalization were carried out to tackle to this issue as in [7, 8] where multi-tap equalization is used.
Usually, linear minimum mean square error (MMSE) equalization is used to compensate the channel effect, since maximum likelihood (ML) detection is computationally impractical.
To solve this problem, the sigmoid function and locally adaptive histogram equalization is used to enhance the contrast of the estimated illumination component [16, 22].
Turbo equalization is used as an alternative to optimal NI-JED, which is not feasible because of computational complexity constraints discussed before, to the extent that approximate inference via the iterative exchange of information is the last resort.
To assess the robustness of the proposed method to various types of filtering and enhancement techniques, frequency mode Laplacian removal, Gaussian lowpass filtering, soft thresholding, hard thresholding, wiener filtering, image sharpening, reduced color, and histogram equalization were used.
In other words, Mr. Dobkin said, when an averaged equalization ratio was used to calculate a single-family house's market value from its assessed value, it would likely produce a calculated market value that was lower than the actual value.
A pressure equalization factor, Ceq, was used as a measure of how much the peak net wind loads on the panels are reduced relative to the peak external loads.
