Paper Abstract

Quantitative evaluation of native biologic cell material can be performed regarding the absorption in ultraviolet light at several specific wavelengths. Due to motion of unfixed cells consecutive images of the cells may be shifted, rotated, and even shrinked. For motion vector analysis each pixel of the cell image sequence is described by a multidimensional feature vector containing local neighbourhood relations. Based on this vector set, the motion vectors are determined by correlation techniques and euclidian distance measurements. The global movement parameters are evaluated from the calculated local motion vectors to compensate the movement of cells between consecutive image scenes. The procedure is presented and demonstrated by experiments for separation of nucleic acid specific and nuclear protein specific structures in unfixed and unstained clinical cell material.
