Dears, Thesedays, I'm studying the image distortion, especially, about the motion blurred images. About these works, I have some questions and I can't find answers myself. My questions are following: 1. When resizing motion blurred images, what types of distortions could be applied...

Dear, I assume that a signal S is expressed as S = a*S1 + b*S2, where a, b are weight constant, and S1, S2 are the different signals. In addition, S1, S2 have similar distribution such as Gaussian or Laplacian distribution, and theirs pdf is p_S1 and p_S2. In the above...

Thank you for your reply. In addition, I have additional question. In the special case, if these two signals are similar (almost same), is there other special relation or equation ?

Dears, I wish to measure the entropy of visual data such as image and video. I did transform these image and videos into frequency domain such as DCT, then measured the entropy with these pdfs for each AC components of image and videos. However, when I measured the entropy over spatial domain...

Dears, If a random variable is generated with the pdf of p(f) = 1/(f^x), how can I derive the upper bound or lower bound of the random variable? Thanks,

Dears, The kurtosis consists of the 4th central moment and the square of variance. It measures the peakedness of the distribution. However, it is hard to understand why 4th central moment is used to measure 'peakedness' of the distribution. What is the 4-th central moment? It looks...

I'm studying on statistics. Then, I saw 'Kurtosis', that represents 'peakness' of the distribution. In the text, the kurtosis is defined as 4-th central moment devided by square of variance. But, I can't understand why the standized 4-th central moment is used. What is the role of the...
