Basic Module 3

IPT, MSI and Blob Toolboxes – an Introduction

Prerequisites: VideometerLab software is installed on the PC. The VideometerLab is connected to the PC and both are turned on. The PC is connected to the internet, user is logged in, and a Microsoft Teams session has been set up.
Tutorials and how to documents are avaiable on the ftp drive. We encourage you to visit these before the training and revisit after the training.
This module typically includes:

1

IPT Menu: Image Processing Toolbox

Frame operations. Simple pixelwise operations performed band by band:
   1. Algebra. Adding, subtracting, dividing etc. image bands
   2. Center image. Make the mean of each band zero by subtracting the mean.
   3. Normalize image. Make the mean 0 and standard deviation 1 for each band by subtracting mean and dividing by standard deviation. 
   4. Fix bad values. NaN and extreme values set to valid pixel values.
Background correction. Correct for uneven background by subtracting a lowpass filtered version of the image. Usually this is done for images with uneven illumination (not from VideometerLab) and for images where fine scale texture is measured after removing coarse scale variation.
Filtering. A selection of image filters for smoothing, edge and line detection and matched filters.
Morphology. A selection of morphological filters operating on local shape characteristics. 
Segmentation. Threshold segmentation for making a decision on what is foreground and what is background. Also segmentation for ridges (Hessian) and along watershed lines.
