A new method for microscopic image mosaic with computer image registration technique is introduced. The mosaic is completed as follows:(1)production of gradient images to facilitate registration.(2)fast registration based on pyramid data structure.(3)boundary processing to eliminate gradients at areas of mosaic.The advantages of this method are that, mosaic is completed by computer automatically,and human bias factors are avoided. The operation is fast and precise. The seams of the mosaic are smooth, which ...
