This work presents a methodology, which is in implementation phase, to detect patterns in fluid flow images. This patterns, in Dynamical Systems Theory, are called critical points or singular points. The methodology is based on this theory concepts and in various works. The method has four fundamentals parts: calculus of orientation field or phase portrait, orientation smoothing and estimative of critical points with description and localization of this patterns. We present some partial results obtained until this moment.
