Source: Polynomial_Surface_Fit.java Requires: jama.jar Installation: Download Polynomial_Surface_Fit.class into the ImageJ/plugins folder or an immediate subfolder. Description: This ImageJ plugin calculates a polynomial surface fit of an image. It's equivalent to applying a low-spatial-frequency filter to the image.
The plugin requires a monochrome image. If the image is a stack the plugin fits the average stack frame. The user is asked to select the fitting polynomial order, currently limited to 0 through 9th-order.
The plugin creates a new image representing the surface fit.
- Outlier pixels can adversely affect the fit so I recommend removing severe outliers prior to using this plugin.
- Using too high a fitting polynomial order will lead to poor fitting.
