The gel electrophoresis is a method of separation of substances possessing electrical charge using the difference of their mobility in the electric field. The rate of migration of a fragment of a protein or DNA depends on the intensity of the constant electric field, on its resultant charge and the friction coefficient [1,2]. The effect of the electrical force is dependent on the fragment shape, its...
The paper presents a new technique of image enhancement. The described algorithm enables the suppression of noise and contrast enhancement. The interesting feature of this new algorithm is that its iterative use leads to the image segmentation. The algorithm is based on a concept of a virtual particle, which performs a special kind of a random walk — the so called self-avoiding random walk. The transition...
