Talk:Horn–Schunck method

From Wikipedia, the free encyclopedia

The original Horn & Shunck method was described in 2 dimensions only (x and y). I think its easier for the reader to imagine the whole thing with just two dimensions (plus time). --Oxygene123 16:08, 31 January 2006 (UTC)

I totally agree, I was very confused, when I read this article...and I am still.
I second that. Three dimensional (or four-dimensional!) "images" are somewhat non-intuitive to the general reader. Any other opinions?65.183.135.231 (talk) 03:23, 5 May 2008 (UTC)

I believe there is an error in the equations, the Laplace operator should be \Delta V_x = \frac{\partial}{\partial x}\frac{\partial V_x}{\partial x}+\frac{\partial}{\partial y}\frac{\partial V_x}{\partial y}+\frac{\partial}{\partial z}\frac{\partial V_x}{\partial z} and analogously for y and z. Also the so claimed Gauss-Seidel formulae seem wrong, as there will be division by zero wherever the derivative is zero.

In the iterative equations given, (certainly for the Gauss-Seidel method) shouldn't the newly computed values be used immediately? Pog (talk) 10:00, 21 November 2007 (UTC)
