Illumination Harmonization with Gray Mean Scale

2020
Illumination harmonization is an important problem for high-quality image composite. Given the source image and the target background, it aims to transform the foreground appearance that it looks in the same lighting condition as the target background.

Harmonic Mean Linear Discriminant Analysis

IEEE Transactions on Knowledge and Data Engineering, 2019
In machine learning and data mining, dimensionality reduction is one of the main tasks. Linear Discriminant Analysis (LDA) is a widely used supervised dimensionality reduction algorithm and it has attracted a lot of research interests. Classical Linear Discriminant Analysis finds a subspace to minimize within-class distance and maximize between-class ...

Harmonic, Logarithmic, and Arithmetic Means and Corollaries

The American Mathematical Monthly, 2020
For two positive real numbers a and b, their harmonic, logarithmic, and arithmetic means are respectively defined by H(a,b)=21a+1b=2aba+b,L(a,b)=b−a ln b− ln a , and A(a,b)=a+b2 .Theorem.
