Pixel Reduction in HCA
Today I was asked by a student, how is it possible that the hierarchical clustering of a Raman image stops with the error message " dataset cannot be reduced because there are too many pixels exhibiting zero distance in the descriptor space ". At first I was puzzled, because a zero distance in the d...

Re: Starting ImageLab with Parameters
Yes, you can start it from the command line and pass either a data file or an ILabPascal script to it. In the script you can do whatever you want, provided that you have a license for the Extended Edition (which is required to execute scripts).

Adding image annotations programmatically
Recently I was asked how to put annotations to an image in order to identify certain pixels. While there is an elaborate annotation tool the question actually was how to create the annotations by an ImageLab script (ILabPascal). Here's a short sample script which shows how to add a few annotations. ...

Re: Elements of a TDouble2DArray
Hi Zuzana, the TDouble2DArray is an open array declared as " array of array of double ". Thus accessing a variable of type TDouble2DArray has to take this into account by using square brackets for each index. Example, assigning a numeric value to a particular cell of the array: var my2da : TDouble2D...

At times it is useful to create an artificial image for testing purposes. You can perform this task by a small ImageLab script. The following code shows how to create and calibrate such an artificial dataset. In the sample code the calibration is done only for the wavelength (=layers of the hypercub...
