Rough Alignment is process that adjusts the position, rotation , magnification, ect... Basically, It determines their position by using the correlation between images. It is the following procedure.
1. Select one of images as a reference (Usually, 0 degree's image), and multiply Windowing Function (mrcImageWindowing) relative to the center.
2. Calculate Correlation Function (mrcImageCorrelation or mrcImageAutoRotationCorrelation) between it and image adjusting position.
3. Move the image. By using mrcImageCorrelation, mrcImageAutoRotationCorrelation (Option -fit/-fit2), you can get both the output of correlation and moved image.
