GEL ELECTROPHORESIS IMAGE COMBINING FOR IMPROVED DYNAMIC RANGE

摘要

A computer-implemented image processing method and apparatus for combining a plurality of gel electrophoresis images. The method includes the steps of fitting the gel electrophoresis pixel intensity values for a subject pixel to a mathematical function, computing from the mathematical function a pixel intensity value according to a predetermined rule, and inserting the pixel intensity value into the composite image. The apparatus includes an image capturing device, and a computer having a memory and communicating with the image capturing device, the computer capable of receiving and storing into the memory a plurality of gel electrophoresis images from the image capturing device, the computer being further capable of fitting a plurality of intensity values of a pixel to a mathematical function over time and computing an optimal pixel intensity value for use in the composite image.
