Approximation of Planar Rational Curves by Polynomial Curves

Hongmei Zhang, Zhigao Zhang, Zhili Pei
A Rational curve r(t) can pass through interpolation points (m+1) by a polynomial of degree m or under some circumstances, and the same is true when rational curve is restricted or the function values of r(t) are replaced by derivatives . The paper will show in these cases a rational curve r(t) of degree...

Adaptive Equalization Algorithm for Image Based on Histogram

Zhigao Zhang, Hongmei Zhang, Zhili Pei
The classical histogram equalization algorithm is not perfect in its over extending low gray layers, which produces over emphasized images and in its weakness in changing gray level, which leads to the lost of details in image. For enhancing the algorithm, the paper introduces an adaptive equalization...
