| + | ==== Normalize ==== | ||
| + | This processor is used to generate normalized images out of the input image stack. This is performed according to the specified mean and sigma values. | ||
| - | ===== Parameters ==== | + | |< 100% 30% >| |
| + | ^ Parameters ^ Description ^ | ||
| + | | Mask | Specifies whether a circular mask is used on the images. | | ||
| + | | -> Auto crop | If activated, automatically crops each image to the minimum size. | | ||
| + | | -> Radius (fraction) | Determines the radius of the applied circular mask. Accepted value range: [0…1] | | ||
| + | | Mean | The desired mean pixel value after normalization. | | ||
| + | | Sigma | The desired pixel value standard deviation after normalization. | | ||
| - | === Mask === | + | ==== Normalize against background ==== |
| - | Specifies whether a circular mask is used on the images | + | Here, standard deviation and mean are calculated based on a user set radius, but only pixels that are outside the specified circle are used during the computation. This technique is used to enhance the signal of the images as usually the outer part contains only noise. While in the initial mean and standard deviation computation only the outside pixel values are used, all pixels are adjusted during the application of the new mean and standard deviation. Inverting the image during computation is also possible. |
