Preprocessing of 1D gel electrophoresis image

By Matej Hlavatý


The aim of this project is an automatic analysis of 1D gel electrophoresis results. Basic principles of gel electrophoresis and types of errors and signal noise influencing the result are studied. The proposed algorithm serves for automatic detection of lanes in the image. Summation projection on the horizontal axis is created from black-and-white digital pictures of electrophoresis. Local minima of the profile are located after smoothing the profile. In the location of these minima borders between lanes are established
