Linear Fit Part 2: Practical Usages

In this lesson we explore some practical uses of Linear Fit while being on the look out for some common pitfalls. Matching a short exposure with a longer one (globular cluster) as well as a starless Ha image and a luminance image are shown. 
Linear Fit Part 1: Theory

In this section on Linear Fit images are graphically compared to show relationships between them in order to show how the fitting (matching) works. 
Morphological Transformation Part 2

This video is part 2 of Morphological Transformation. 

 
Morphological Transformation Part 1

This video examines Morphological Transformation in detail. The working part of the tool is the small matrix ("kernel" like structure) that employs the rule (operator) to output new pixel values. This method of interacting with data in images is a fundamental (though generally hidden) form of image processing that is beneficial to understand. 
Noise Generator

The video on this page explains the surprising benefits of PI's NoiseGenerator process. Counterintuitively it can be used to solve problems by adding noise.
LRGB Downloads

Some files for the LRGB Blending session are available to download from here. 
LRGB Blending

This video (teaser) describes the inner workings of LGRB Combination and the techniques used to manage the results. Typically image processors do not pay much attention to this step and simply combine the images...but there is much more to it! Join AdamBlockStudios to see the full video. 
Pixel Math Downloads and Expressions

This page has process icons and scripts to download relevant to Pixel Math.
History Explorer

This video explains the features of the History Explorer. This is part of PixInsight Fundamentals. 
Process Container

This video concerns Process Containers as explained in the PixInsight Fundamentals collection. 
Image and Process Containers

This video shows an example of using both Image and Process containers simultaneously to batch process images. This video is part of the PixInsight Fundamentals collection. 

 
Image Container

This video demonstrates the use of the Image Container in the PixInsight Fundamentals series. 
Selective Rejection (new)

This is the newer version of the Selective Rejection video for the Pixinsight Fundamental series.

“The videos are outstanding. I've been using PI exclusively to process my images for some years now and accordingly have some experience and proficiency with the program. Nonetheless, found the videos to be very helpful and informative. Particularly useful are your easy to follow explanations of how the various tools and processes work. I feel certain that these tutorials will significantly shorten the learning curve for both new and experienced users.”
