www.pharmtech.com rational approach to scale-up has been used in the physical sciences for quite some time. This approach, called dimensional analysis, is a proven method of developing functional relationships that describe any given process in a dimensionless form to facilitate modeling and scale-up or scale-down. This short article reviews and demonstrates the dimensional analysis method as a...

This paper studies the robustness of SIFT and SURF against different image transforms (rigid body, similarity, affine and projective) by quantitatively analyzing the variations in the extent of transformations. Previous studies have been comparing the two techniques on absolute transformations rather than the specific amount of deformation caused by the transformation. The paper establishes an ...
