Essay from the year 2023 in the subject Computer Science - Bioinformatics, , course: bionics, language: English, abstract: When evaluating image data from flow analyses, the task emerges to quantify the quality of currents that exist in the afterlife of a interference contour. The image data comes from laboratory experiments on the wind tunnel or are the calculation result from computer simulations. The intervention names a procedure of digital image processing, which is suitable for detection in densities in speed fields of regular flow fields.
