Is it possible to perform a number of image transform operations on an image and generate a lookup table that maps each original pixel location to its new location? I want to use this LUT output as an input in a different software to mass-process the same pixel reassignment on each frame of streaming video.

Provided the transformations only move entries:
temp_img = reshape(1:numels(YourImage), size(YourImage));
Now do your transformation on temp_img . The result will be an array of linear indices:
mapped_idx = Do_all_the_moving_transformations(temp_idx);
example_mapped_image = YourImage(mapped_idx);
another_mapped_image = YourOtherImage(mapped_idx);
