[improvement] Streaks in projections during alignment

[swelborn]

During alignment, streaks appear in the dataset. This could be due to 1 of 2 things:

1. Downsampling the data introduces the streaks because of the padding.

• solution: pad after downsampling the data. Would require downsampling the padding.

2. Shifting the data introduces these streaks.

• unsure of solution here. maybe use filter?

streaking could cause alignment to not work effectively - phase correlation could capture these streaks instead of the features.
