SUMMARY

The discussion focuses on using the Stretched Exponential Decay function to correct intensity decay in a stack of images, where the first image has maximum intensity and subsequent images show significant decay. The user derived an expression for the alpha value in the exponential function \( e^{(-\alpha x)}^\beta \), with alpha dependent on beta, which ranges from 0 to 1. The main challenge is determining the optimal alpha and beta values for effective intensity correction, with a query about the applicability of least squares for this optimization.

Hi!
Iam using Streched exponentail decay function to correct the intensity decay of a stack of images in which the first iamge in the stack have maximum intensity and decay exp so taht the last iamge in the stack have alomost nothing to see . I derived an expression to find the alpha value in the exponantial function(e^(-alpahx)^beta) which is the correction parameter.The alpha value value depends on the beta value which ranges from 0-1. Now my problem is to find the optimum alpha and beta values from the set of (alpha,beta ) so that the intensity correction is optimum.
whether laest sqaure can be used for this. which isthe best way to find
